Description
TECHNICAL AREA
[0001] The present invention relates to a composition for the production of a polyurethane foam, which contains a polyalkylene oxide-modified arylsulfonic acid ester as an additive, and to the use of the arylsulfonic acid ester in the production of a polyurethane foam. BACKGROUND
[0002] Polyurethane foams are frequently used in automotive applications such as seat cushions, headrests, dashboards, headliners, and steering wheels. Due to the requirement to minimize the use of volatile organic compounds (VOCs), amine catalysts are employed, which can be incorporated into the polyurethane foam either as high-molecular-weight catalysts or as reactive catalysts (reactive towards isocyanates). While these reactive or low-emission amine catalysts contribute only minimally to emissions in the standard automotive test VDA 278, their use negatively impacts the wet-heat aging resistance of PU foams. Therefore, it is a crucial technical challenge to develop additives that can be used, for example, in conjunction with low-emission amine catalysts as components in PU systems or PU foams, thereby increasing the resistance of PU foams to hydrolysis aging (wet-heat aging).
[0003] Some of the known additives for improving wet heat aging properties have the disadvantage that they can only be mixed with the other formulation components, especially catalysts and water, relatively shortly before the foaming process, as otherwise they greatly reduce the gel and blowing catalysis of the respective PU system over a period of a few hours to a few days.
[0004] EP 1 834 974 A3 describes the use of aromatic diesters to improve the physical properties of foams after moist heat storage. However, the effect of the diesters is relatively weak; in particular, they only achieve a very slight improvement in the moist heat aging resistance of TDI foams.
[0005] US20190100638A1 utilizes halohydrins (compounds with at least one halogen function (e.g. chlorine, bromine) and at least one OH function (e.g. 6-chlorohexan-1-ol)) to improve physical foam properties after moist heat storage.
[0006] US 2022 / 0033603 A1 describes the use of structurally diverse chlorinated hydrocarbon compounds to improve the foaming properties of polyurethane foams after humid heat storage. However, chlorinated hydrocarbon emissions are undesirable because they can be toxic.
[0007] WO 2022034151 A1 discloses that sulfonic acid esters added as additives improve the hydrolysis (and heat) resistance of polyurethane foams. PU foams exposed to high temperatures and high humidity exhibit significantly poorer material properties due to wet heat aging. The material properties of PU foams containing sulfonic acid esters are less affected (damaged) by wet heat aging. However, a crucial disadvantage of the sulfonic acid esters described in WO 2022034151 A1 is their low stability in PU systems. Consequently, in PU system premixes of polyols, amine catalysts, water, sulfonic acid esters according to WO 2022034151 A1, and optional additional components, the catalytic effect of the respective amine catalyst or amine catalyst mixture decreases significantly over a period of a few hours to several days.The emission levels from the compound described in WO 2022034151 A1 are also too high.
[0008] The aim of the present invention was therefore to develop additives that improve the resistance of foams to damp heat aging, exhibit high stability as a component in PU systems, and do not affect, or only very slightly affect, the catalytic activity and associated foam growth behavior of the respective PU system even after storage. Likewise, the additives should result in no or only very low foam emissions in the VDA 278 emissions test commonly used in the automotive industry.
[0009] Surprisingly, arylsulfonic acid esters according to the present invention exhibit particularly good storage stability as an additive to PU systems premixed prior to foaming and result in improved resistance of the foams to damp heat aging as well as low foam emissions according to VDA 278.

[0013] The term "contains" is not intended to exclude other components, process steps, etc. Furthermore, the term "contains" – in conjunction with individual characteristics, such as composition – can be further restricted or replaced by the term "consisting of".
[0014] Range specifications, such as 1 to 10, should also disclose the numbers within the range that are not explicitly disclosed. For example, 1 to 10 also discloses the numbers within this range, such as 2, 3, 4, 5, 6, 7, 8, and 9. The lower and upper limits of range specifications for the respective features can be combined with the lower and upper limits of the individually preferred or optional ranges.
[0015] Unless otherwise stated, percentages are given as weight percent, which refers to the total weight of the respective composition.
[0016] The quantity given in "pphp" ("parts per hundred polyol") means the weight fraction per 100 parts by weight of polyol (total polyol) in the composition. For example, 1.0 pphp of substance A means 1.0 g of substance A per 100 g of polyol in the composition.
[0017] Terms described in the singular also include the plural form. For example, polyol means that one or more polyols may be present that fall under the term polyol.
[0018] The present invention relates to a composition for the production of a polyurethane foam, comprising: (a) a polyol, (b) an amine catalyst, (c) a blowing agent, (d) arylsulfonic acid ester (arylsulfonic acid ester according to the invention).
[0019] The arylsulfonic acid ester (d) comprises a single arylsulfonic acid ester but also mixtures of arylsulfonic acid esters.
[0020] The composition according to the invention for producing a polyurethane foam can also be referred to as a PU system (polyurethane system), PU system premix (polyurethane system premix), or PU foam mixture (polyurethane foam mixture). In particular, it is a polyurethane foam. Specifically, the composition is a premix for producing a polyurethane foam.
[0021] The arylsulfonic acid ester or arylsulfonic acid ester according to the invention is one (or more) arylsulfonic acid esters according to compound (I) (alternatively formula (I)): where a is 0 to 20, preferably 1 to 20, more preferably 2 to 15, particularly preferably 2 to 12, b is 0 to 20, preferably 0 to 15, more preferably 0 to 12, particularly preferably 0. c is 0 to 20, preferably 1 to 20, more preferably 2 to 15, particularly preferably 2 to 12; the sum of a + c is 0 to 20, preferably 3 to 15, particularly preferably 4 to 12. each R 1 independently of each other hydrogen, methyl or ethyl, especially preferably methyl, is, each R 2 independent of each other hydrogen, methyl or ethyl, especially preferably hydrogen, is each R 3 independently of each other hydrogen, phenyl, or an alkyl group C1-C 16 , preferably hydrogen, methyl or ethyl, particularly preferably methyl, is, each R 4 independently of each other hydrogen, phenyl, or an alkyl group C1-C 16 , preferably hydrogen, methyl or ethyl, particularly preferably methyl, is, R 5 Hydrogen, 2,6-di-tert-butyl-4-methylphenyl, alkyl group C1-C 16, -C(O)Me, a residue according to formula (i) or a residue according to formula (ii), preferably hydrogen, methyl, ethyl, isopropyl, n-butyl, n-octyl, n-dodecyl, a residue according to formula (i) or a residue according to formula (ii), particularly preferably hydrogen, a residue according to formula (i) or a residue according to formula (ii), is, where R 6 Hydrogen, phenyl, or alkyl group C1-C 10 , preferably hydrogen, methyl or ethyl, is, each R 7 independently of each other hydrogen, phenyl, or an alkyl group C1-C 16 , preferably hydrogen, methyl or ethyl, particularly preferably methyl, is, each R 8 independently of each other hydrogen, phenyl, or an alkyl group C1-C 16 , preferably hydrogen, methyl or ethyl, particularly preferably methyl, is, each R 9 independently of each other hydrogen, 2,6-di-tert-butyl-4-methylphenyl, alkyl group C1-C 16, -C(O)Me, or a residue according to formula (i), preferably hydrogen, methyl, ethyl, isopropyl, n-butyl, n-octyl, n-dodecyl, or a residue according to formula (i), particularly preferably hydrogen, or a residue according to formula (i), is, Y is oxygen or -CH2-O-, d is 0 to 25, preferably 1 to 20, more preferably 2 to 15, particularly preferably 2 to 12, e is 0 to 25, preferably 1 to 20, more preferably 2 to 15, particularly preferably 2 to 12, the sum d + e is 0 to 20, preferably 1 to 15, particularly preferably 4 to 12. if R 5 If the remainder is not the remainder according to formula (ii), then the sum a + b + c is 4 to 20, preferably 4 to 15, particularly preferably 4 to 12. if R 5 If the remainder is according to formula (ii), then the sum a + b + c + d + e is 4 to 40, preferably 4 to 30, more preferably 5 to 25, particularly preferably 6 to 20.
[0022] If no separate indications for the above-mentioned indices, substituents and / or residues (such as "a", "b", "c", "R") are given in formulas / residues / compounds 1" , “R 2" where mentioned (e.g.), the information applies accordingly to the subordinate formulas, such as the subordinate formulas: Formula (12), Formula (i), Formula (ii), etc.
[0023] The dashed line in, for example, formula (i) is intended to indicate where the structure is connected. For example, for formula (I) and R, this would result in... 5 = Formula (i) following formula (I1):
[0024] In formula (11) there are two R each 1 and R 2 depicted and the expert can independently R 1 and R 2 select. This applies accordingly to the remaining remainders R. x , like R 2 , R 3 , R 4 , R 6 , R 7 , R 8 and R 9However, it is preferred that all respective R x (R 1 , R 3 , R 4 , R 6 , R 7 , R 8 and R 9 ) have the same residues.
[0025] Accordingly, for the formulas according to the invention, it is preferred that each R 1 Hydrogen, methyl or ethyl, especially preferably hydrogen, is, each R 2 Hydrogen, methyl or ethyl, especially preferably methyl, is, each R 3 Hydrogen, phenyl, or an alkyl group C1-C 16 , preferably hydrogen, methyl or ethyl, particularly preferably methyl, is, each R 4 Hydrogen, phenyl, or an alkyl group C1-C 16 , preferably hydrogen, methyl or ethyl, particularly preferably methyl, is, each R 5 Hydrogen, 2,6-di-tert-butyl-4-methylphenyl, alkyl group C1-C 16, -C(O)Me, a residue according to formula (i) or a residue according to formula (ii), preferably hydrogen, methyl, ethyl, isopropyl, n-butyl, n-octyl, n-dodecyl, a residue according to formula (i) or a residue according to formula (ii), particularly preferably hydrogen, a residue according to formula (i) or a residue according to formula (ii), R 6 Hydrogen, phenyl, or alkyl group C1-C 10 , preferably hydrogen, methyl or ethyl, is, each R 7 Hydrogen, phenyl, or an alkyl group C1-C 16 , preferably hydrogen, methyl or ethyl, particularly preferably methyl, is, each R 8 Hydrogen, phenyl, or an alkyl group C1-C 16 , preferably hydrogen, methyl or ethyl, particularly preferably methyl, is, each R 9 Hydrogen, 2,6-di-tert-butyl-4-methylphenyl, alkyl group C1-C 16, -C(O)Me, or a residue according to formula (i), preferably hydrogen, methyl, ethyl, isopropyl, nButyl, nOctyl, nDodecyl, or a residue according to formula (i), particularly preferably hydrogen, or a residue according to formula (i).
[0026] The designations that each R 3 independently of each other hydrogen, phenyl, or an alkyl group C1-C 16 , preferably hydrogen, methyl or ethyl, particularly preferably methyl, is, and each R 4 independently of each other hydrogen, phenyl, or an alkyl group C1-C 16 The subscript "a" means that in each repeating unit with the index "a", the repeating units can have a different substituent. This is the case, for example, in polyether tosylate 3 (additive 7) according to the examples. This also applies accordingly to the repeating units with the indices "d" and "e".
[0027] In principle, at least four repeating units (a + b + c + d + e) should be present in the arylsulfonic acid ester according to the invention. If the residue according to formula (ii) is not present in the arylsulfonic acid ester according to the invention, then d and e are equal to 0, and thus a + b + c + 0 + 0 = a + b + c. As described above, if R 5 not the remainder according to formula (ii), the sum a + b + c be 4 to 20, preferably 4 to 15, particularly preferably 4 to 12 and if R 5 If the remainder is according to formula (ii), then the sum a + b + c + d + e should be 4 to 40, preferably 4 to 30, more preferably 5 to 25, particularly preferably 6 to 20.
[0028] The catalytic effect of the respective amine catalyst or amine catalyst mixture in a composition could be improved with the arylsulfonic acid ester according to the invention during storage over a period of a few hours to a few days.
[0029] Surprisingly, arylsulfonic acid esters, especially those with a sulfonic acid-esterified propylene oxide end group, e.g., -[CH2-C(CH3)HO]-SO3-C6H5CH3, exhibit particularly good storage stability as additives in pre-mixed polyurethane (PU) systems. PU systems pre-mixed are primarily those that do not yet contain any isocyanate functional groups.
[0030] Furthermore, the arylsulfonic acid esters according to the invention significantly improve the physical foaming properties of PU foams after moist heat aging compared to low-molecular-weight sulfonic acid esters. In addition, the arylsulfonic acid esters according to the invention are non-volatile, so their use results in no or only very low foam emissions in the VDA 278 emission test commonly used in the automotive industry.
[0031] The arylsulfonic acid esters according to the examples in the inventive composition are particularly preferred for the production of a polyurethane foam. These exemplary arylsulfonic acid esters can be used in the amounts according to the inventive.
[0032] The preferred arylsulfonic acid ester (b) is that according to compound (I2): where a is 0 to 20, preferably 1 to 20, more preferably 2 to 15, particularly preferably 2 to 12, c is 0 to 20, preferably 1 to 20, more preferably 2 to 15, particularly preferably 2 to 12, each R 1 independently of one another hydrogen, methyl or ethyl, especially preferably methyl, is, each R 2 independent of each other hydrogen, methyl or ethyl, especially preferably hydrogen, is each R 3 independently of each other hydrogen, phenyl, or an alkyl group C1-C 16, preferably hydrogen, methyl or ethyl, particularly preferably methyl, is, each R 4 independently of each other hydrogen, phenyl, or an alkyl group C1-C 16 , preferably hydrogen, methyl or ethyl, particularly preferably methyl, is, R 5 Hydrogen, 2,6-di-tert-butyl-4-methylphenyl, alkyl group C1-C 16 , -C(O)Me, a residue according to formula (i) or a residue according to formula (ii), preferably hydrogen, methyl, ethyl, isopropyl, n-butyl, n-octyl, n-dodecyl, a residue according to formula (i) or a residue according to formula (ii), particularly preferably hydrogen, a residue according to formula (i) or a residue according to formula (ii), is, where R 6 Hydrogen, phenyl, or alkyl group C1-C 10 , preferably hydrogen, methyl or ethyl, is, each R 7 independently of each other hydrogen, phenyl, or an alkyl group C1-C 16 , preferably hydrogen, methyl or ethyl, particularly preferably methyl, is, each R 8 independently of each other hydrogen, phenyl, or an alkyl group C1-C 16 , preferably hydrogen, methyl or ethyl, particularly preferably methyl, is, each R 9 independently of each other hydrogen, 2,6-di-tert-butyl-4-methylphenyl, alkyl group C1-C 16 , -C(O)Me, or a residue according to formula (i), preferably hydrogen, methyl, ethyl, isopropyl, n-butyl, n-octyl, n-dodecyl, or a residue according to formula (i), particularly preferably hydrogen, or a residue according to formula (i), is, Y is oxygen or -CH2-O-, d is 0 to 25, preferably 1 to 20, more preferably 2 to 15, particularly preferably 2 to 12, e is 0 to 25, preferably 1 to 20, more preferably 2 to 15, particularly preferably 2 to 12; the sum d + e is 0 to 20, preferably 1 to 15, particularly preferably 4 to 12. if R 5If the remainder is not the remainder according to formula (ii), then the sum a + c is 4 to 20, preferably 4 to 15, particularly preferably 4 to 12. if R 5 If the remainder is according to formula (ii), then the sum a + c + d + e is 4 to 40, preferably 4 to 30, more preferably 5 to 25, particularly preferably 6 to 20.
[0033] The present invention also comprises a method for producing a polyurethane foam, comprising (A) providing the composition according to the invention, (B) mixing the composition from step (A) with a compound having isocyanate functional groups, and (C) producing the polyurethane foam from the mixture obtained in step (B).
[0034] The composition can be free of a compound with isocyanate functional groups. In this case, it would be a premix. A compound with isocyanate functional groups can then be added to the premix to produce the foam. According to the invention, the composition can be mixed or prepared as early as 21 days before the addition of the compound with isocyanate functional groups without significantly impairing the foam properties (short rise time).
[0035] Accordingly, the time between (A) providing or preparing the composition and (B) mixing the composition and the reaction from step (A) with a compound having isocyanate functional groups can be 12 hours to 30 days, preferably 1 day to 21 days, more preferably 1 day to 15 days, particularly preferably 1 day to 9 days, most preferably 1 day to 3 days.
[0036] The composition according to the invention can be provided as a kit, wherein a first component is the composition according to the invention and a second component contains a compound with isocyanate functional groups.
[0037] The composition according to the invention may already contain (e) a compound with isocyanate functional groups. This is usually the case shortly before foam production.
[0038] The compound with isocyanate functional groups can comprise hexamethylene diisocyanate (HDI), phenylene diisocyanate (PDI), toluene diisocyanate (TDI), diphenylmethane diisocyanate (MDI), and / or isophorone diisocyanate (IPDI), preferably toluene diisocyanate (TDI) and / or diphenylmethane diisocyanate (MDI), particularly preferably toluene diisocyanate (TDI).
[0039] The compound with isocyanate functional groups (isocyanate component) can contain 2,4-TDI, 2,6-TDI, or a combination thereof. The isocyanate functional groups (isocyanate component) can contain crude MDI, for example, a mixture of about 60% 4,4'-MDI and / or a stoichiometric amount, together with other isomers and analogous higher polyisocyanates. Other suitable isocyanates are those of US Patent No. 4,394,491, which are part of this invention.
[0040] TDI molded foams with amine catalysts (or with reactive and / or non-volatile amine catalysts) are, in contrast to MDI molded foams, even more sensitive to hydrolysis aging or humid heat storage. The composition and method according to the invention, containing the arylsulfonic acid ester (b) according to the invention, results in a significant improvement in the physical foam properties of TDI foams after humid heat storage.
[0041] The amount of compound containing isocyanate functional groups is typically based on an NCO index. The NCO index is the number of isocyanate equivalents divided by the total number of equivalents of active hydrogen (e.g., from the polyol), multiplied by 100 (e.g., based on an NCO index of [NCO / (OH+NH)]*100). The composition can have an NCO index of 70 to 500, or 70 to 115. An NCO index of 70 to 115 is commonly used when the composition is intended for the production of flexible foams. The weight mixing ratio of the composition or premix to the compound containing isocyanate functional groups can range from 1:1 to 3:1. The composition can contain 10 to 40 wt.% of the compound with isocyanate functional groups, preferably 10 to 35 wt.%, particularly preferably 20 to 30 wt.%, based on the total weight of the composition.
[0042] The composition according to the invention contains a polyol (a). Polyols are organic compounds with at least two hydroxyl groups. The polyol can be any polyol suitable for the production of polyurethane foams. In principle, the polyol reacts with a compound having isocyanate functional groups to obtain a polyurethane. Suitable polyols can be found in WO 03 / 016373 A1, WO 01 / 58976 A1, WO 04060956 A1, WO 03 / 016372 A1, and WO 03 / 055930 A1, and these polyols in the designated applications are part of this invention. Accordingly, the polyol should be a polyol that can react with a compound having isocyanate functional groups.
[0043] Suitable polyols include polyether polyols or copolymers of polyether polyols. The polyol can be polyether polyol, poly(alkylene oxide) polymers such as poly(ethylene oxide), poly(propylene oxide), and / or copolymers with terminal hydroxyl groups derived from polyhydric compounds (e.g., diols and triols). The polyol can have a molecular weight of 4500 to 7000 g / mol and / or 2000 to 4000 g / mol. Diols and triols, which also belong to the group of polyols, can be ethylene glycol, propylene glycol, 1,3-butanediol, 1,4-butanediol, 1,6-hexanediol, neopentyl glycol, diethylene glycol, dipropylene glycol, pentaerythritol, glycerol, diglycerol, trimethylolpropane, other suitable low molecular weight polyols, or a combination thereof. The polyol can be a polyhydroxy-terminated acetal resin, a hydroxy-terminated amine, a hydroxyl-terminated polyamine, or a combination thereof.The polyol can be a polyalkylene carbonate-based polyol, a phosphate-based polyol, or a combination thereof.
[0044] Suitable polyols can also be found in the examples.
[0045] The polyol may contain copolymer polyols. Copolymer polyols can constitute up to approximately 20% of the total polyol content by weight. The copolymer polyols improve the polyurethane foam formed by the composition by increasing its resistance to deformation and thereby enhancing its load-bearing properties. The copolymer polyol may be a graft polyol, a polyurea-modified polyol, or a combination thereof, or it may comprise one of these.
[0046] The graft polyol is any suitable graft polyol. It can be prepared by copolymerization of vinyl monomers (e.g., styrene and acrylonitrile) with a suitable starting polyol. The starting polyol can be a glycerol-initiated triol end-capped with ethylene oxide (e.g., with 80% to 85% primary hydroxyl groups). The graft polyol then comprises a copolymer grafted onto the starting polyol, homopolymers of the vinyl monomers, and the starting polyol (in its original form). The graft polymer can contain styrene or acrylonitrile at a concentration of approximately 5% to 45% by weight.
[0047] The polyurea-modified polyol is formed by the reaction of a diamine and a diisocyanate in the presence of the starting polyol. The polyurea-modified polyol contains a polyurea dispersion. The polyurea-modified polyol can be a polyisocyanate polyaddition polyol (PIPA), which is formed, for example, in situ from a reaction between the compound with isocyanate functional groups and an alkanolamine.
[0048] The polyol can be present in an amount of 50 to 98 wt.%, preferably 70 to 97 wt.%, more preferably 80 to 96 wt.%, particularly preferably 85 to 95 wt.%, based on the total weight of the composition.
[0049] The propellant (c) can be any suitable propellant. Propellants are compounds that react, for example, with isocyanate and form a gas. Propellants can be carbon dioxide, chlorofluorocarbons, hydrogenated fluorocarbons, hydrogenated chlorofluorocarbons, fluoroolefins, chlorofluoroolefins, fluorocarbons, hydrochlorofluoroolefins, acetone, low-boiling hydrocarbons (e.g., cyclopentane, isopentane, n-pentane, or a combination thereof), water, or a combination thereof. It is particularly preferred that the propellant (c) is water. Thus, component (c) would be water. The propellant can be present in the composition in an amount of 0.02 to 10 wt.%, preferably 0.1 to 8 wt.%, more preferably 1 to 7 wt.%, and particularly preferably 1.5 to 5 wt.%, based on the total weight of the composition. Water can be added in an amount of 0.02 to 10 wt.%, preferably 0.1 to 8 wt.%, more preferably 1 to 7 wt.%.-%, particularly preferably 1.5 to 5 wt.%, based on the total weight of the composition, shall be contained in the composition.
[0050] The composition may further contain an additive selected from a cell stabilizer, a crosslinking agent, a chain extender, a pigment, a filler, a flame retardant, a urethane gel auxiliary catalyst, and a propellant catalyst, or combinations thereof.
[0051] The composition may additionally contain a cell stabilizer. Cell stabilizers contain silicone-based surfactants, anionic surfactants, or a combination thereof. The cell stabilizer may be a silicon-based surfactant, such as polyalkylsiloxane, polyoxyalkylene polyol-modified dimethylpolysiloxane, alkylene glycol-modified dimethylpolysiloxane, or a combination thereof. The cell stabilizer preferably does not contain an acyl group. The silicone surfactant may contain an acyl group. The cell stabilizer may be an anionic surfactant, such as a fatty acid salt, a sulfuric acid ester salt, a phosphate ester salt, a sulfonic acid salt, or a combination thereof. The composition may contain a cell stabilizer in an amount of 0.1 ppm to 20 ppm, 0.1 ppm to 10 ppm, or 0.1 ppm to 5 ppm.
[0052] The composition may contain a crosslinking agent. Crosslinking agents can be low-molecular-weight compounds containing at least two residues, such as hydroxyl groups, primary amino groups, secondary amino groups, other active hydrogen-containing groups that are reactive with an isocyanate group, or a combination thereof.
[0053] The crosslinking agent can be a polyhydric alcohol (e.g., a trihydric alcohol such as glycerol or trimethylolpropane), a polyamine, or a combination thereof. A polyamine can be diethyltoluenediamine, chlorodiaminobenzene, diethanolamine, diisopropanolamine, triethanolamine, tripropanolamine, 1,6-hexanediamine, or a combination thereof. In an embodiment where the crosslinking agent is a diamine, the crosslinking agent contains twelve or fewer carbon atoms, seven carbon atoms, or fewer than seven carbon atoms.

Additives 2 and 3 are short-chain, monomeric tosylates according to the prior art.Additive 4 is tetraethylene glycol bistosylate (abcr GmbH) and is used to produce compositions according to the invention. The production of additives 5 to 11 is described below. General description of the production of additives
[0152] Prior to the synthesis of the arylsulfonic acid esters according to the invention, the preceding polyether alcohols (polyoxyalkylenes) were either commercially acquired (e.g. pTHF) 250 from BASF) or according to established methods, which are briefly described below. Various publications in the prior art describe the use of alcohols, carboxylic acids, or amines as starting compounds for the alkoxylation reaction to polyether alcohols (polyoxyalkylenes). A good overview of polyoxyalkylenes and methods for their preparation is provided by "N. Schönfeldt, Surface Active Ethylene Oxide Adducts, Pergamon Press, 1969".
[0153] The polyoxyalkylenes used as starting materials in connection with the synthesis of the polyethersulfonic acid according to the invention are preferably colorless to yellow-orange liquids with low viscosity at room temperature (preferably up to about 1000 mPas), which can be clear or opaque.
[0154] The polyether alcohols used in connection with this invention, unless they were commercially acquired, were produced according to the following process: In the first step, a starting compound is reacted with epoxides such as ethylene oxide, propylene oxide, butylene oxide, or any mixtures of these epoxides using a catalyst. Alkaline catalysts known to those skilled in the art, such as potassium hydroxide, potassium hydroxide, sodium methoxide, potassium methoxide, or double metal cyanide compounds, are used as catalysts for the alkoxylation reaction. The starting compound and catalyst are introduced into the reactor at the beginning of the process, prior to the addition of the alkylene oxide, with the amount of catalyst being adjusted to ensure sufficient catalytic activity for the process. The reaction temperature of the first step is preferably between 80 and 220 °C, and particularly preferably between 100 and 180 °C. The pressure of the first step is preferably between 0.5 bar and 20 bar, and more preferably between 1.0 bar and 12 bar (absolute).
[0155] The epoxide monomers can be used in pure form or mixed to obtain homopolymers or statistical copolymers. Following the addition of a first monomer or monomer mixture, further monomers can be added to obtain block structures. Alternatively, the addition of further epoxides to an epoxide already present in the reaction mixture can be carried out continuously over time, creating an increasing concentration gradient of the continuously added epoxide. The relationship between dosage and product structure is well known to those skilled in the art.
[0156] After the completion of the epoxide addition, a secondary reaction typically follows to complete the conversion. This secondary reaction can be carried out, for example, by continuing the reaction under controlled conditions (i.e., maintaining the temperature and pressure) without adding any reactants. Preferably, the secondary reaction is carried out by mixing the reaction mixture, particularly by stirring.
[0157] In an optional second step, residual monomers are removed by vacuum distillation and, if necessary, the reaction product is neutralized with an acid such as lactic acid, acetic acid, propionic acid or phosphoric acid, and the resulting salts are removed by filtration if necessary.
[0158] In principle, any suitable reactor type that can control the reaction and its heat of reaction can be used for the alkoxylation in the first process step. The first process step can be carried out continuously, semi-continuously, or batchwise in a manner known in process engineering.
[0159] For the polyether alcohols used here, the number-average molar masses determined by the determination of the hydroxyl number are usually used as a basis for subsequent reactions.

General production of polyurethane molded foams for testing additives to improve properties after humid heat storage or for determining volatile components using thermal desorption analysis
[0169] The polyurethane foams were produced in the laboratory as so-called molded foams according to formulations 1, 2, 3, and 4. The foams were produced according to the following specifications at 22 °C and 762 mm Hg atmospheric pressure. A heated aluminum mold with dimensions of 40 × 40 × 10 cm was used for foam production. The mold temperature was either 50 ± 2 °C (formulations 1, 2, and 4) or 60 ± 2 °C (formulation 3). Prior to foam production, the mold was treated with a solvent-based release agent.

[0170] For the production of the polyurethane molded foams according to formulations 1 and 2 (MDI formulations), 600 g of the polyol Arcol were used in each case. ® 1374 was used, for foams according to formulation 4 (also MDI) 700 g Arcol was used. ® 1374 was used. For the production of polyurethane molding foams according to formulation 3 (TDI formulation), 420 g of the polyol Hyperlite were used. ® 1629 and 180 g of the polyol Hyperlite ® 1650 was used. The other formulation components were converted accordingly. For example, 1.0 part (1.0 pphp) of a component meant 1.0 g of that substance per 100 g of polyol (formulations 1, 2 and 4: polyol is Arcol). ® 1374, Formulation 3: Polyol is Hyperlite ® 1629). For example, formulation 1 contains 0.71 g of the crosslinking agent DABCO® DEOA 85 per 100 g of Arcol. ®1374. To produce the corresponding foam, the polyols were combined with all other formulation components except the diisocyanate and the additive, and mixed for one minute with a paddle stirrer at 1000 revolutions per minute to form a premix.
[0171] Subsequently, within a few seconds, 337 g of methylenediphenyl diisocyanate (formulations 1 and 2), 405 g of methylenediphenyl diisocyanate (formulation 4), or 201 g of toluene diisocyanate (formulation 3, isomer ratio 2,4-toluene diisocyanate : 2,6-toluene diisocyanate = 80 : 20) was added to the respective premix mentioned above, and the mixture was stirred for 7 seconds at 2500 revolutions per minute. The polymerizing and foaming reaction mixture was transferred to the aluminum mold within a few seconds, and the mold was sealed until demolding. After 4 minutes (formulations 1 and 2), 5 minutes (formulation 3), or 4.5 minutes (formulation 4), the finished foam cushion was removed. The foam cushion was then manually pressed into place. The foam body was weighed and conditioned for at least 168 hours at constant temperature and humidity before being cut to size and further tests were carried out. Example 1: Physical properties of the test foams
[0172] The foams produced, along with the quantities of additives used and their foam properties, are listed in the following tables. Moist heat storage and application-related tests of the foam properties a) Moist heat storage
[0173] Humid aging of the test specimens was carried out in accordance with DIN EN ISO 2440. The specimens were exposed to water vapor at 120 °C or 100% relative humidity for 15 hours. After humid aging, the specimens were dried for 3 hours at 70 °C in a drying oven with air exchange. For simplicity, measurement results from specimens after humid aging are marked HA (Humid Aged), while results for specimens without humid aging are marked amb (ambient). b) Measurement of compression hardness (compressive stress under compression)
[0174] The compressive stress was determined for both unaged and humid-aged foam test specimens measuring 7 x 7 x 3 cm at a compression of 40% in accordance with DIN EN ISO 3386:2015-10. After measuring the compressive stress, the respective unaged foam test specimen was subjected to humid heat storage and subsequently, after drying and conditioning, retested for compressive stress. The measured values were given in kilopascals. The decrease in the compressive stress of the foam test specimen after humid heat storage is also referred to as HALL (Humid Aged Load Loss). c) Measurement of compression set
[0175] Five specimens measuring 5 cm x 5 cm x 2.5 cm were cut from each of the finished foams. The initial thickness d0 was measured. The compression set DVR (50% / 22 h / 70°C) was measured for both unaged and moist-heat-aged foam specimens in accordance with DIN EN ISO 1856:2020-11. For this purpose, the specimens were compressed to half their thickness (i.e., to 12.5 mm) and then placed in an oven at 70 ± 1 °C for 22 hours. The relaxation time until the thickness d was measured again was [not specified in the original text]. r (After relaxation) was 30 minutes. The results are given as a percentage according to the following formula: DVR=(d0-d r ) / d0 x 100% (d0 = original thickness, d r (Thickness after relaxation). The compression set of the respective test specimens after humid heat storage is also referred to as HACS (humid Aged Compression Set). d) Measurement of tensile strength and elongation at break
[0176] The tensile strength (at fracture) and elongation at break were determined in accordance with DIN EN ISO 1798:2008-04. Tensile strength values are given in kilopascals (kPa), and elongation at break values in percent (%).

[0178] Table 5 shows the results of measurements of the physical properties of MDI foams with the additives 4, 5, 7, 8, 9, 10, 11, and 12 according to the invention, compared to a foam without a moist heat storage additive (foam 1) and foams with non-inventive additives 1, 2, and 3 (foams 2, 3, 4, and 5). Moist heat storage of MDI foams generally leads to a deterioration in compression hardness (CLD) and compression set. The purpose of using the moist heat storage additives in MDI foams is to counteract this deterioration (increase) in compression set and to prevent a significant decrease in compression hardness. For foam 1 without a moist heat storage additive, the compression set after moist heat storage is 31.5%. With the non-inventive additive 1 (foam 2), an improvement of 23.7% is achieved. However, foam 2 exhibits an undesirably high decrease in compression hardness of 46.5%.With the non-inventive additives 2 and 3, a significant improvement in compression set after moist heat storage is also observed. However, additives 2 and 3 exhibit crucial disadvantages, such as a substantial contribution to foam emissions and low stability in polyurethane systems, which will be illustrated in more detail later. Surprisingly, the use of the additives according to the invention achieves very good values for compression set, which in some cases are below 25% and in some cases even below 21%. The reduction in tensile strength upon fracture after moist heat storage is also minimized by the use of the additives according to the invention compared to foam 1.

[0180] Table 6 shows the results of measurements of the physical properties of MDI foams according to formulation 2 with the additives 5, 6, and 9 according to the invention, compared to a foam without a moist heat storage additive and a foam with the non-inventive additive 2. Formulation 2 differs from formulation 1 in that DABCO® NE 1550 is used as a purely amine reactive gel catalyst. As with the non-inventive additive 2, the use of the additives 5, 6, and 9 according to the invention results in a significant improvement in the compression set after moist heat storage compared to the foam without additives (foam 19). All of the additives mentioned also increase the tensile strength at fracture after moist heat storage.

[0182] Table 7 shows the results of the measurements of the physical properties of the TDI foams according to formulation 3 with the additives 5, 9, and 11 according to the invention, compared to a foam without the moist heat storage additive and to the non-inventive additive 3. In contrast to the MDI foams of formulations 1 and 2, the TDI foams according to formulation 3 are generally even more sensitive to moist heat storage, as demonstrated by the example of foam 26 (without additive). Unlike MDI foams, the compression set of the TDI foams according to formulation 3 is not critically impaired by moist heat storage. Therefore, the following discussion will focus particularly on the effect of the additives according to the invention on the change in compression hardness, tensile strength, and elongation at break after moist heat storage. The compression hardness of foam 26 (without the moist heat storage additive) decreases significantly by 67.7% after moist heat storage.The tensile strength and elongation at break of the test specimens of foam 26 are not measurable, as they tear immediately upon being pulled apart. Overall, humid heat storage thus causes a significant deterioration of the material properties of foam 26. When using the additives 5, 9, and 11 according to the invention, the decrease in compression hardness after humid heat storage can always be limited to less than 43%, which demonstrates an improvement in the mechanical integrity of the foams. In the case of foams 30, 31, and 32, even excellent values of reductions in compression hardness of less than 25% are observed. The use of the additives also results in a substantial improvement in tensile strength and elongation at break. Furthermore, it can be seen that with the use of additives 5 and 11, an increased amount of the respective additive leads to a further increase in tensile strength. Example 2: Test method for determining the influence of additives on the rise time of polyurethane foam (test on free-rising foam)
[0183] To determine the rise times, a mixture according to formulation 2 was prepared with all components except the methylenediphenyl diisocyanate (see above) and additionally treated with 1 pphp of the corresponding additive. After storage times of 1, 3, 6, 9, and 21 days, respectively, 108 g of the mixtures were stirred for one minute at 1000 rpm and then treated with 56.2 g of methylenediphenyl diisocyanate (Suprasec 2447). After the addition of the methylenediphenyl diisocyanate, the already polymerizing mixtures were stirred for 7 seconds at 2500 rpm and transferred to an open-topped, approximately cylindrical cardboard beaker with a circular base of 168 cm². 2The foam was given a specific temperature and height. Using a height measuring system (device type FOAMAT® 285, measuring principle: ultrasound), the rise time required for the foam to reach 98% of its maximum height was then determined. The rise time of the freshly mixed system according to formulation 2 without additives was approximately 87 + / - 2 seconds. If the foam's rise was not complete after 5 minutes, a rise time greater than 300 seconds was recorded.
[0184] Table 8. Influence of the moist heat storage additives on the rise time of polyurethane foam system (formulation 2) after storage for up to 21 days. The rise time corresponds to the measured time at which 98% of the maximum foam height is reached and is shown in seconds (s). If the rise process was not complete after 5 minutes or 300 seconds, a rise time > 300 seconds was reported; X = not measured.

[0185] Table 8 shows the rise time of an MDI-polyurethane foam system according to formulation 2, which is required until the respective foam reaches 98% of its final height. For the foam system without additives, rise times of 87–90 seconds were measured from the measurement immediately after mixing until foaming after 21 days of storage. The small variation of 3 seconds shows that the reactivity of the system does not change, or changes almost not, over the period of 21 days or three weeks.
[0186] When using the non-inventive additive 1, the rise time changes only minimally, by less than 5 seconds, over the measurement period. In contrast, the use of the non-inventive additive 2 (methyl tosylate) leads directly to an increase in the rise time to 102 seconds immediately after mixing the system without further storage, thus resulting in a significant delay in the rise behavior. After one day of storage of the system with additive 2, it was foamed again. This time, the rise behavior was extremely delayed, so that the foam's rise process was not yet complete even after 300 seconds. The test system with the non-inventive additive 3 shows no delay compared to the formulation without the additive immediately after mixing. However, after 21 days, an increased rise time of 110 seconds is measured.When using the polyether tosylates 1, 3, 5, 6, 7, and 8 according to the invention, only polyether tosylates 1 and 6 show a slight increase in the rise time after 21 days. Surprisingly, polyether tosylates 3, 5, 7, and 8 have no or only a negligible effect on the rise time after storage for up to 21 days. Thus, these polyether tosylates manage to combine high system stability (negligible effect on the rise time after storage) with a very good improvement in physical properties after humid heat storage. Example 3: Thermal desorption analysis for foams according to VDA 278
[0187] Foams (according to formulation 4) containing both prior art additives and the additives according to the invention were investigated using thermal desorption analysis according to VDA 278. The emissions attributable to an additive were determined by measuring the VOC or FOG value of the respective foam and subtracting the blank value measured in the analysis of a foam without the additive. Example: VOC (additive in foam 33) = VOC (foam 33) - VOC (reference foam without additive). Table 9 lists the additives used and the measurement results.
[0188] The materials are characterized with regard to the type and quantity of organic substances that can be outgassed from them. For this purpose, two semi-quantitative sum values are determined, allowing an estimation of the emission of volatile organic compounds (VOC value) and the proportion of condensable substances (FOG value). Furthermore, individual emitted substances are determined. During the analysis, the samples are thermally extracted, the emissions are separated by gas chromatography, and detected by mass spectrometry. The total concentrations obtained for the VOC fraction are calculated in toluene equivalents, yielding the VOC value; the FOG fraction is expressed in hexadecane equivalents, yielding the FOG value.
[0189] This analytical method is used to determine emissions from non-metallic materials used in molded parts for motor vehicles, including foams. In thermal desorption analysis (TDS), small quantities of material are heated in a desorption tube under controlled conditions. The emitted volatile substances are cryofocused in a cold trap of a temperature-programmable evaporator using an inert gas stream. After the heating phase, the cold trap is rapidly heated to 280°C. The focused substances then evaporate. They are subsequently separated in a gas chromatographic column and detected by mass spectrometry. A semi-quantitative estimation of the emission, expressed in µg / g, is possible through calibration with reference substances. Toluene is used as a quantitative reference substance for VOC analysis (VOC value), and n-hexadecane for the fog value.Substances can be identified based on their mass spectra and retention indices. Source: VDA 278 / 10.2011, www.vda.de.
[0190] The determined amount of benzaldehyde is expressed in toluene equivalents (mg / g). Analytical test specimens: sample preparation, sampling, and specimen dimensions.
[0191] After demolding, the foams are stored for 24 hours at 21°C and approximately 50% relative humidity. Samples are then taken from suitable and representative locations, evenly distributed across the width of the (cooled) molded part. The foams are then wrapped in aluminum foil and sealed in a polyethylene bag. Each sample contains 10-15 mg of foam, which is inserted into the desorption tube. Test procedure: VOC / FOG thermal desorption.
[0192] Immediately upon receipt of the sealed samples, they are subjected to direct analysis. Before the start of the analysis, the samples are weighed on an analytical balance to an accuracy of 0.1 mg, and the corresponding amount of foam is placed in the center of the desorption tube. A stream of helium is passed over the sample, which is then heated to 90°C for 30 minutes. All volatile substances are collected in a cold trap cooled with liquid nitrogen. After 30 minutes, the cold trap is heated to 280°C. The evaporating substances are separated from each other using the described gas chromatographic column and subsequently analyzed by mass spectrometry.
[0193] Instrument parameters GC-MS. The following instrument is used for the analysis: Gerstel GmbH, Eberhard-Gerstel-Platz 1, D-45473 Mühlheim an der Ruhr, TDS-3 / KAS-4 Tenax® desorption tubes, Agilent Technologies 7890A (GC) / 5975C (MS), column: HP Ultra2 (50 mL, 0.32 mm, 0.52 mm), carrier gas: helium.
[0194] Table 9: Additive-induced foam emissions according to thermal desorption analysis according to VDA 278. Additive quantity is given in ppm, as is the quantity of VOC or FOG relative to the proportion of the foam mass in ppm, and the quantities of the various additives are given in ppm. Foam number VB33 VB34 VB35 VB36 37 38 39 40 41 42 Additive 1 - not in accordance with the invention 1,0 Additive 2 - Methyl tosylate, not according to the invention 1,0 Additive 3 - n-Octyl tosylate, not according to the invention 1,0 2,0 Additive 4 - Tetraethylene glycol bistosylate according to the invention 1,0 2,0 Additive 6 - Polyether tosylate 2, according to the invention 1,0 Additive 8 - Polyether tosylate 4, according to the invention 2,0 Additive 9 - Polyether tosylate 5, according to the invention 2,0 Additive 11 - Polyether tosylate 7, according to the invention 1,0 VOC [ppm] 10 90 113 200 10 10 10 20 40 10 FOG [ppm] 10 30 401 649 10 10 60 170 370 30
[0195] Additive 1 exhibits very low contributions to foam emissions of only 10 ppm in both the VOC and FOG ranges. Even though the foam emissions of Additive 1 are low, the emission of toxic chlorinated hydrocarbons is undesirable.
[0196] In the case of additives 2 and 3 (short-chain, monomeric tosylates) not according to the invention, relatively high emissions of 90–113 ppm in the VOC range are found at an application rate of 1 ppm. For the polyether tosylates according to the invention (including additive 4 – tetraethylene glycol bistosylate), only low VOC values below 50 ppm are found at application rates of 1–2 ppm. This shows that, compared to the low-molecular-weight tosylates, the polyether tosylates not only exhibit significantly better system stability (negligible influence on the rise time after storage) and improved physical properties after humid heat storage, but also a more advantageous VOC and emission profile. The FOG values of the foams containing the polyether tosylates are also very low compared to additive 3 – especially for polyether tosylates 2 and 7. QUOTES INCLUDED IN THE DESCRIPTION
