Description

[Technical field]

[0001] The present invention relates to compositions comprising moisture crosslinkable polymers, and to methods for producing moisture crosslinkable polymers, especially silane-functional hybrid polymers, and to the moisture crosslinkable polymers themselves. In a further aspect, the present invention relates to the use of these compositions in the CASE sector (coatings, adhesives, sealants and elastomers), such as, for example, adhesives and sealants.

[0002] For example, polymers such as silylated polyurethanes that condense ("crosslink") on contact with water or air humidity at room temperature have been known for a long time. They are also called moisture-crosslinkable polymers. Depending on factors including the content of silane groups and their structure, it is possible to form extensive reticulated three-dimensional networks or highly crosslinked systems of long chain polymers. [Background technology]

[0003] Moisture crosslinkable polymers, especially silylated polyurethanes, have long found a variety of uses as adhesives and sealants. For example, the field of traditional silicone adhesives and sealants based on dimethylpolysiloxane, as well as polyurethane adhesives and sealants with free isocyanate groups, has been developed to include silane-terminated adhesives and sealants.

[0004] In the production of polyurethane-containing materials (PU), the skilled person is fundamentally aware of metal-siloxane-silanol (silanolate) compounds as catalysts, for example from EP 3063209 (B1) and US Pat. No. 7,737,228 (B2).

[0005] EP2989155(B1) further discloses the curing of silylated polymer (SiP), especially silylated polyurethane, using oligomeric metallosilsesquioxane (POMS).Moisture crosslinkable silylated polymer generally has poor storage stability.Therefore, measures are typically required to improve the stability of polymer during storage, for example, by adding water scavengers to respective compositions. It is therefore an object of the present invention to provide compositions comprising at least one silylated polymer (SiP) that have improved storage stability. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] European Patent No. 3,063,209 [Patent Document 2] U.S. Patent No. 7,737,228 [Patent Document 3] European Patent No. 2,989,155 Summary of the Invention [Means for solving the problem]

[0007] This object is achieved according to the present invention by providing a composition obtainable according to claim 1. Advantageous developments are the subject matter of dependent or further independent claims.

[0008] Thus, the core of the present invention is the provision of silylated polymers (SiPs) by the reaction of at least one isocyanate-containing compound with at least one isocyanate-reactive compound catalyzed by a metal-siloxane-silanol (silanolate) compound. Particularly preferred are silylated polymers obtainable by the synthesis of at least one hydroxy-functionalized polymer (also "hydroxy-functional polymer") with a compound having at least one isocyanate group catalyzed by a metal-siloxane-silanol (silanolate) compound. Effect of the Invention

[0009] It has been surprisingly found that the silylated polymers created by the present invention have improved storage stability.This is shown, for example, in that when the SiPs created in this way are cured, the fiber time and / or tack-free time are extended, compared to the SiPs synthesized in the presence of conventional catalysts.This is true both without the addition of additional catalyst for curing and after the addition of additional catalyst (see Table A).

[0010] Those skilled in the art recognize that there are two parameters of the speed of the curing operation: fiber time and tack-free time. Fiber time (also called film time) indicates the start of the curing reaction or crosslinking of the polymer. Tack-free time provides a value that indicates the end of the outer film curing. In particular, even for the production of silylated polymers (SiP), the use of at least one metal-siloxane-silanol (silanolate) compound as a catalyst has been found to be particularly effective in terms of the resulting storage stability. Despite the extension of fiber time and / or tack-free time, the silylated polymers (SiP) according to the present invention have good and moderate curability.

[0011] The use of metal-siloxane-silanol (silanolate) compounds according to the invention further surprisingly allows the synthesis of silylated polymers (SiP) at lower temperatures. The synthesis is preferably possible at temperatures below 80°C, preferably below 60°C, more preferably below 40°C, and most preferably even at room temperature. One advantage of lower temperatures is that the formation of undesired by-products (e.g. ureidoformamide) is reduced. This may contribute to a higher specificity of the crosslinking reaction.

[0012] In addition to the conservation of resources and the reduction of undesirable by-products due to lower energy demand, the composition according to the present invention may also have improved processability. This may be due to the lower viscosity, which is typical under some circumstances, of the composition according to the present invention compared to SiPs created using conventional catalysts. A comparison of the viscosity of the composition created by using DBTL as a catalyst according to the prior art and TiPOSS according to the present invention (as an example of the catalyst used according to the present invention), as well as their reactivity, is shown in Table A.

[0013] A further advantage of the compositions according to the invention is that it allows for the use of reduced levels of, or entirely avoidance of, tin-containing catalysts.

[0014] The particular efficiency of the metal-siloxane-silanol (silanolate) compounds as catalysts, both in the production of the silylated polymers (SiPs) according to the invention and in the subsequent curing of the compositions according to the invention, allows for an overall reduction in the use of catalysts. Depending on the reactants used to produce the silylated polymers (SiPs), the amount of catalyst required can be in the range of 20 to 5000 ppm, preferably in the range of 20 to 200 ppm, or in the range of 3000 to 4800 ppm.

[0015] This efficiency is also manifested in the fact that the compositions according to the invention allow the use of ethoxy-functionalized silanes without unduly reducing the reactivity of the SiP obtained using the invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] A "polymer" is a chemical compound that consists of chain or branched molecules (macromolecules). Polymers are made up of several identical / equal units, called monomers, or different units. Polymers also include oligomers. Oligomers are polymers with a smaller number of units. Unless explicitly defined differently, oligomers are included in the concept of polymer according to the present invention. Polymers can exist as homopolymers (= made up of only one type of monomer unit), copolymers (= made up of two or more types of monomer units) or as polymer mixtures (= polymer alloys, polymer blends, i.e. mixtures of various polymers and copolymers).

[0017] In the context of the present invention, a "silylated polymer" is a silane-modified, silane-functional or silane-terminated polymer, also referred to interchangeably as SMP, STP or SiP. This definition includes polymers, polycondensates or polyadducts.

[0018] This also includes moisture-curable polymers that can be cured under the influence of water, either by addition of water or via a mixture that consists of or contains water, or by contact with air humidity, preferably with the additional use of a catalyst.

[0019] Silane-functional polymers are also referred to as hybrid polymers in common usage and according to the present invention. These polymers can combine the curing chemistry of alkoxysilane groups with the chemistry of polyols or polyurethanes. Alkoxysilane groups are known from silicone chemistry. An isocyanate-functional polymer, especially a hydroxy-functional polymer, contributes at least a part of the polymer backbone of the hybrid polymer. Crosslinking ("curing") is carried out via reactive silane end groups, for example by the ingress of air moisture. The curing mechanism of these systems is preferably neutral.

[0023] "Optionally substituted" means that a hydrogen atom in the corresponding group or in the corresponding radical may be replaced by a substituent. The substituent may be selected in particular from the group consisting of C1-C4-alkyl, methyl, ethyl, propyl, butyl, phenyl, benzyl, halogen, fluorine, chlorine, bromine, iodine, hydroxy, amino, alkylamino, dialkylamino, C1-C4-alkoxy, phenoxy, benzyloxy, cyano, nitro and thio. When a group is referred to as being optionally substituted, 0 to 50, in particular 0 to 20, hydrogen atoms of the group may be replaced by a substituent. When a group is substituted, at least one hydrogen atom is replaced by a substituent.

[0024] The term "alkyl group" is to be understood as meaning a saturated hydrocarbon chain. An alkyl group is in particular a group of the general formula -C n H 2n+1 The term "C1-C16-alkyl group" especially denotes a saturated hydrocarbyl chain having 1 to 16 carbon atoms in the chain. Examples of C1-C16-alkyl groups are methyl, ethyl, propyl, butyl, isopropyl, isobutyl, sec-butyl, tert-butyl, n-pentyl and ethylhexyl. Correspondingly, "C1-C8-alkyl group" especially denotes a saturated hydrocarbyl chain having 1 to 8 carbon atoms in the chain. The alkyl group may also especially be substituted, even if this is not specifically stated.

[0025] A "straight chain alkyl group" refers to an alkyl group that does not contain a branch. Examples of straight chain alkyl groups are methyl, ethyl, n-propyl, n-butyl, n-pentyl, n-hexyl, n-heptyl and n-octyl.

[0026] "Branched alkyl group" refers to an alkyl group that is not linear, i.e., the hydrocarbyl chain has, inter alia, a branch. Examples of branched alkyl groups are isopropyl, isobutyl, se These are c-butyl, tert-butyl, sec-pentyl, 3-pentyl, 2-methylbutyl, isopentyl, 3-methylbut-2-yl, 2-methylbut-2-yl, neopentyl, ethylhexyl and 2-ethylhexyl.

[0027] An "alkenyl group" describes a hydrocarbon chain containing at least one double bond along the chain. For example, an alkenyl group with a double bond has inter alia the general formula -CnH2n-1. However, an alkenyl group may also have more than one double bond. The term "C2-C16-alkenyl group" inter alia describes a hydrocarbyl chain having 2 to 16 carbon atoms in the chain. The number of hydrogen atoms varies according to the number of double bonds in the alkenyl group. Examples of alkenyl groups are vinyl-, allyl-, 2-butenyl- and 2-hexenyl-.

[0028] A "straight-chain alkenyl group" refers to an alkenyl group that does not contain a branch. Examples of straight-chain alkenyl groups are vinyl, allyl, n-2-butenyl, and n-2-hexenyl.

[0029] A "branched alkenyl group" refers to an alkenyl group that is not linear, i.e., the hydrocarbyl chain specifically has a branch. Examples of branched alkenyl groups are 2-methyl-2-propenyl, 2-methyl-2-butenyl and 2-ethyl-2-pentenyl.

[0030] "Aryl group" refers to monocyclic (e.g., phenyl), bicyclic (e.g., indenyl, naphthalenyl, tetrahydronaphthyl or tetrahydroindenyl), and tricyclic (e.g., fluorenyl, tetrahydrofluorenyl, anthracenyl or tetrahydroanthracenyl) ring systems, where at least one of the rings in the monocyclic ring system, or the bicyclic or tricyclic ring system, is aromatic. More particularly, C4-C14-aryl group refers to an aryl group having 4 to 14 carbon atoms. The aryl group may also be specifically substituted, even if this is not specifically stated.

[0031] For example, it is possible to use moisture-curable silylated polymers in the compositions according to the invention, especially silylated polyethers and / or silylated polyurethane polymers (SPUR). The silylated polymers or silane-terminated polymers that may be used in the compositions according to the invention contain at least two or more reactive silane groups, such as alkoxysilanes.

[0032] One example of a possible silylated polymer that can be utilized according to the present invention is an oxyalkylene polymer having at least one reactive silane group at each end of the polymer molecule. The backbone of the silane-terminated oxyalkylene polymer according to the present invention comprises repeat units of the general formula (1): -RO- (1) wherein R is a divalent organic group, preferably a linear or branched alkylene group containing 1 to 14 carbon atoms, more preferably a linear or branched alkylene group containing 2 to 4 carbon atoms, or mixtures thereof. Most preferred are polypropylene oxide backbones, polyethylene oxide backbones and copolyethylene oxide / copolypropylene oxide backbones, or mixtures thereof. Other repeating units can include, but are not limited to, the following units: -CH2-O-, -CH2CH(CH3)O-, -CH2CH(C2H5)O-, -CH2C(CH3)O-, -CH2CH2CH2CH2O- and others of similar structure.

[0033] The reactive silane group in the silylated polymer (SiP) has the following formula (2): -Si(R 2 ) 3-a (G) a (2) (In the formula, R 2 are each independently a C1-C20 alkyl group, a C6-C20 aryl group, a C7-C20 aralkyl group or a mixture thereof; G may represent a hydrolyzable group or a hydroxyl group, and if two or more G are present, they may be the same or different; - a is an integer from 1 to 3. It can be described by:

[0034] In the reactive silane group described by formula (2), at least one hydrolyzable or hydroxy group is represented by G.

[0035] According to the invention, "hydrolyzable groups" are those that can undergo hydrolysis reactions under the influence of water, for example from air humidity or by the addition of water or aqueous constituents, and as a result can form silanols. Hydrolyzable groups can be, for example, alkoxy groups or, less commonly, -Cl. These groups (or the silanols formed thereby) can likewise react with OH or COOH groups of the surface to form composites.

[0036] In the context of this invention, a "silanol" is an organosilicon compound in which at least one hydroxyl group (OH) is bonded to a silicon atom (-Si-OH).

[0037] In the context of the present invention, a "silanolate" is an organosilicon compound in which at least one deprotonated hydroxy functional group (RO-) is bonded to a silicon atom (-Si-O-), where this negatively charged oxygen atom may also be chemically covalently bonded and / or coordinated to a further compound, e.g., a metal.

[0038] According to the present invention, isocyanate-reactive compounds are those capable of reacting with isocyanates. These compounds may have one or more NH, OH or SH functional groups.

[0039] The isocyanate-reactive compounds include, inter alia, the class of hydroxy-functional compounds. Polyols are hydroxy-functional compounds, especially hydroxy-functional polymers. Polyols suitable for the preparation of polyurethane polymers are, inter alia, polyether polyols, polyester polyols and polycarbonate polyols, as well as mixtures of these polyols.

[0040] "Polyethers" are a class of polymers. They are long-chain compounds that contain at least two identical or different ether groups. According to the present invention, polyethers also include those in which the polymeric ether groups are interrupted by another group (e.g., copolymerized / incorporated isocyanates, or further polymeric or oligomeric units of various monomeric origins).

[0041] Suitable polyether polyols, also called polyoxyalkylene polyols or oligoetherols, are, inter alia, optionally substituted with starter molecules having two or more active hydrogen atoms, such as water, ammonia or compounds having multiple OH or NH groups, such as ethane-1,2-diol, propane-1,2-diol or propane-1,3-diol, neopentyl glycol, diethylene glycol, triethylene glycol, the isomeric di- and tripropylene glycols, the isomeric butanediols, pentanediols, heptanediols, hex ...

[0042] It is possible to use either polyoxyalkylene polyols with low degrees of unsaturation (measured according to ASTM D-2849-69 and expressed in milliequivalents of unsaturation per gram of polyol (meq / g)), produced, for example, using so-called double metal cyanide complex catalysts (DMC catalysts), or polyoxyalkylene polyols with relatively high degrees of unsaturation, produced, for example, using anionic catalysts such as NaOH, KOH, CsOH or alkali metal alkoxides. Polyoxyethylene polyols and polyoxypropylene polyols, especially polyoxyethylene diols, polyoxypropylene diols, polyoxyethylene triols and polyoxypropylene triols, are particularly suitable.

[0043] Particularly preferred are polyoxyalkylene diols or triols having a degree of unsaturation of less than 0.02 meq / g and a molecular weight in the range of 1000 g / mol to 30000 g / mol, as well as polyoxyethylene diols, polyoxyethylene triols, polyoxypropylene diols and polyoxypropylene triols having a molecular weight of 200 to 20000 g / mol. Particularly preferred are the so-called ethylene oxide-terminated ("EO end-capped", ethylene oxide end-capped) polyoxypropylene polyols. The latter are obtained, for example, when pure polyoxypropylene polyols, especially polyoxypropylene diols and triols, are further alkoxylated with ethylene oxide at the end of the polypropoxylation reaction, and are therefore special polyoxypropylene polyoxyethylene polyols with primary hydroxyl groups. In this case, polyoxypropylene polyoxyethylene diols and polyoxypropylene polyoxyethylene triols are preferred. Likewise suitable are hydroxyl-terminated polybutadiene polyols, such as those produced by polymerization of 1,3-butadiene with allyl alcohol, or by oxidation of polybutadiene and also its hydrogenation products.Similarly suitable are styrene-acrylonitrile grafted polyether polyols, such as those available under the trade name Lupranol® from Elastogran GmbH (Germany).

[0049] Likewise suitable are polyhydrocarbon polyols, also called oligohydrocarbonols, such as polyhydroxy-functional ethylene-propylene, ethylene-butylene or ethylene-propylene-diene copolymers, such as those produced by Kraton Polymers (USA), or polyhydroxy-functional copolymers of dienes, such as 1,3-butadiene or mixtures of dienes, and vinyl monomers, such as styrene, acrylonitrile or isobutylene, or polyhydroxy-functional polybutadiene polyols, such as those produced by copolymerization of 1,3-butadiene with allyl alcohol, which may be hydrogenated.Also suitable are polyhydroxy-functional acrylonitrile / butadiene copolymers, such as those which can be produced from epoxides or aminoalcohols and carboxyl-terminated acrylonitrile / butadiene copolymers, such as those commercially available under the name Hypro®CTBN from Emerald Performance Materials, LLC (USA).

[0050] Likewise, these particularly preferred polyols may have an average molecular weight of 250 to 40 000 g / mol, in particular 1000 to 30 000 g / mol, and an average OH functionality in the range from 1.6 to 3.

[0054] Surprisingly, it has been found that the silylated polymers (SiP) of the composition according to the invention as claimed in claim 1 are particularly advantageous in the composition according to the invention if metal-siloxane-silanol (silanolate) compounds are used as catalysts in their production.

[0055] The term "catalyst" refers to a substance that lowers the activation energy of a particular reaction, thus increasing the rate of the reaction.

[0056] The term "metal-siloxane-silanol (silanolate)" refers to all metal-siloxane compounds that contain either one or more silanol and / or silanolate groups. In one embodiment of the present invention, exclusively metal-siloxane-silanolates are considered as well.

[0062] For purposes of this invention, a "cage", or oligomeric or polymeric "cage structure", is a three-dimensional array of catenated metal-siloxane-silanol (silanolate) compounds, where the individual atoms in the chain form the vertices of the multi-faceted base structure of the compound. The interconnected atoms form at least two surfaces, resulting in a common intersection. In one embodiment of the present invention, for example, a cubic base structure of the compound is formed. A compound having one cage structure or another monomorphic cage structure, i.e., an isolated cage, is structure (IVc). Compounds having multiple cages within the compound can be described by compounds (I) and (Ia)-(Id). According to the present invention, the cage can be "open" or otherwise "closed" depending on whether all vertices are bonded, connected or coordinated to form a closed cage structure. An example of a closed cage is structure (II), (IV), (IVb), (IVc).

[0063] According to the present invention, the term "core" indicates the nuclearity of the compound, i.e., how many metal atoms are present in it. A mononuclear compound has one metal atom, while a polynuclear or binuclear compound has two metal atoms in the compound. The metals may be directly bonded to each other or may be linked via their substituents. An example of a mononuclear compound according to the present invention is, for example, structure (IV), (IVb), (IVc), (Ia), (Ib) or (Ic). A binuclear compound is represented by structure (Id).

[0064] Mononuclear one-cage structures are represented by the metal-siloxane-silanol (silanolate) compounds (IV), (IVb) and (IVc). Mononuclear two-cage structures are, for example, structures (Ia), (Ib) or (Ic).

Examination of the cure characteristics of silane-terminated polymers STP1-STP6 derived from reactions B1-B6

[0122] The cure characteristics of the silane terminated polymers were tested by determining the fiber time FT and tack free time TFT for 2 mm thick samples at 23° C. / 50% RH with and without further addition of TiPOSS and DBTL. [Table A] Conclusion:

[0123] The clear extension of the fiber or tack-free time for the silane-terminated polymers prepared with TiPOSS (STP1, STP3 and STP5, without further catalyst addition, marked area of ​​the table) indicates that it was possible to clearly improve the stability with respect to the ingress of water (humidity, residual moisture, formulation raw materials, etc.) compared to the compounds prepared with DBTL.

[0124] The advantages obtained are briefly outlined below:

[0125] As a result, the method has the advantage of processing hybrid polymers that are less sensitive to hydrolysis, which means in particular that: 1. Residual moisture from other components and raw materials of the sealant formulation in the compound is not a major issue. 2. Processing reliability is further improved. 3. The storage stability of the composition according to the invention is improved. 4. Less water scavengers (e.g. VTMO, which is toxic if inhaled according to EU-GHS classification and identification H332 and highly flammable according to H225) are required for hybrid polymer stabilization and sealant formulations. 5. It is possible to use lower levels of tin-containing catalysts, preferably avoiding tin-containing catalysts altogether. 6. Generally, less catalyst is required. Example II

[0126] The present invention also relates to compositions and methods for producing polyurethane prepolymer and polyurethane systems based on polyols, di- or polyisocyanates, and TiPOSS-based catalysts.

[0127] The preferred TiPOSS-based catalysts according to the present invention are those disclosed in EP 2989155 (B1) and EP 2796493 (A1). The disclosures of these documents are fully incorporated with respect to the catalyst. The catalysts according to claim 5 of EP 2989155 (B1) (metallosilsesquioxanes) are particularly preferred.

[0128] The activity of heptaisobutyl POSS-titanium(IV) ethoxide (TiPOSS) to form polyurethane compounds was investigated in comparison with dibutyltin dilaurate (DBTDL) and tin(II) 2-ethylhexanoate (stannous octoate) as examples in various non-foamed and foamed polyurethane systems. Particular attention was given to the influence on the preparation of silylated polyurethanes (SPURs) by the IPDI route. Here, model formulations from the CASE application sector, soft and flexible foams (slabstock foams), with TiPOSS and DBTDL or stannous octoate at the same catalyst content and using various polyols and isocyanates, at room temperature (23°C / 50% RH), were tested for their curing characteristics. For simplicity, the study was carried out under the assumption that a perfect stoichiometric reaction (index 100) can occur between the isocyanate and the polyol. In principle, the study is also applicable to the preparation of prepolymers. The catalytic activity of the tested catalysts was judged by determining and comparing the cream time, fiber time and tack-free time. 1.) Study of TiPOSS / DBTDL in non-foamed polyurethane formulations a) Propylene glycol polyol

[0129] The polyol A component is polypropylene diol and diisononyl phthalate (D The polyol A component consisted of TiPOSS catalyst in the form of a 20% solution in INP. To compare the catalytic activity, the same corresponding polyol A component was prepared using DBTDL. The amount of catalyst was in each case 0.2% by weight (ignoring the amount of solvent). To study the influence of the molecular weight, it was further changed from low (MW about 2000) to high (MW about 18000) molecular weight, since it can be assumed that the reactivity of polypropylene polyols with limited reactivity further decreases with increasing molecular weight and therefore the differences in reactivity can be particularly easily observed. Thus, the polypropylene polyols tested had MW about 2000 (Rokopol D2002, PCC Rokita), MW about 8000 (Rokopol LDB8000), MW about 12000 (Rokopol LDB12000) and MW about 18000 (Rokopol LDB18000).

[0130] The crosslinker components used were isocyanate P-MDI (Voranate M230, Dow), IPDI (Wanate IPDI, DKSH) and HDI trimer isocyanurate (Vestanat HT2500 / 100). The reaction between the polyol A and isocyanate B components was carried out by stirring the two components at 1000 rpm with a conventional propeller stirrer for 10 seconds. After the stirring process was completed, the resulting reaction mixture was cast into slabs with a thickness of about 6 mm (10 g). The cure characteristics were determined from cream time, fiber time and tack-free time.

[0131] It was found that the curing of polyurethanes catalyzed by TiPOSS at room temperature is significantly accelerated when using the polypropylene polyols described compared to the corresponding crosslinking catalyzed by DBTDL. The reaction acceleration for the tested polyol and isocyanate combinations is between 2 and 100 times. In the overall context, the reaction acceleration factor when using TiPOSS is particularly surprising in the case of the isocyanurate of the HDI trimer used, and only to a lesser extent in the case of IPDI. Conclusions of the SPUR methodology:

[0132] This finding is very important, since the reaction between DMC polyol and IPDI isocyanate is a key reaction for the commercial preparation of SPUR (hybrid polymers). Since the inventors have already been able to establish a large increase in the reaction at room temperature and with a 1:1 stoichiometry, it can be expected that under conventional conditions of SPUR prepolymer preparation it will be possible to operate with a significantly smaller amount of catalyst (1 / 5-1 / 10) and / or at lower temperatures (<80°C) and / or at shorter reaction times. Since the formation of by-products in this preparation leads to an undesirable increase in viscosity, a separate improvement in reaction regime and product quality is therefore expected.

[0133] With regard to the growing economic importance of SPUR products, the use of TiPOSS catalysts is expected to offer both cost and product advantages over tin catalysts. a) Tip treatment with propylene glycol polyol or ethylene glycol

[0134] To assess whether these observations are also applicable to reactive polyether polyols, as examples, polyether polyols with MW about 4000 and f=2 and MW about 4850 and f=3, terminated with ethoxy groups at the ends, were tested. The difference in reactivity of the polyol systems catalyzed by TiPOSS and DBTDL was found to be smaller when reactive polyether triols were used. Again, it was observed that the acceleration of crosslinking reactivity by TiPOSS was particularly effective in the case of HDI trimers. 2.) Examination of the activity of TiPOSS / DBTL in silane-terminated polyurethanes

[0135] The rate of fiber formation and curing in silane-terminated polyurethanes was The viscosity was determined on 6 mm SPUR slabs produced by mixing 0.2 wt.% each of TiPOSS and DBTL (each in a 20% solution in DINP). The mixing was carried out with a conventional propeller stirrer in an argon inert gas atmosphere with the exclusion of air. The mixed material was cured at 23°C / 50% RH. 3.) Examination of the activity of TiPOSS / DBTDL in flexible polyurethane foam formulations

[0136] The polyol A component consisted of a polyether triol (Rokopol M5020, f=3) whose reactive head was treated with an ethoxy group, water and a TiPOSS catalyst in the form of a 20% solution in diisononyl phthalate (DINP). To compare the catalytic activity, the same corresponding polyol A component was prepared using DBTDL. The catalyst amount was in each case 0.2% by weight (the amount of DINP solvent was neglected). By comparison, the reaction was carried out using a less reactive polypropylene polyol (Rokopol D2002, f=2).

[0137] The crosslinking component used was Isocyanate P-MDI (Voranate M230). The reaction between the Polyol A component and the Isocyanate B component was carried out by stirring the two components at 2500 rpm with a conventional propeller stirrer for 10 seconds. The reaction was stoichiometric. After the stirring process was completed, the resulting reaction mixture (20 g) was poured into a cup. The cure characteristics were determined from the cream time and tack-free time.

[0138] When using ethoxylated polyols, the activity of TiPOSS was found to be comparable to that of DBTDL. By contrast, the curing process in the case of formulations made from pure polypropylene polyol is accelerated much more by TiPOSS. 4.) Examination of the Activity of TiPOSS / Stannic Octoate in Slabstock Polyurethane Foam Formulations

[0139] The polyol A component consisted of a standard polyester polyol based on Desmophen 2200B, amine catalysts (N,N-dimethylpiperazine and N,N-dimethylhexadecylamine), foam stabilizer, water, and TiPOSS catalyst in the form of a 20% solution in DINP. To compare the catalytic activity, the same corresponding polyol A component was prepared using stannous octoate. The amount of TiPOSS and stannous octoate catalyst was 0.03% by weight in each case.

[0140] The crosslinking components used were the isocyanate Desmodur T65 and a prepolymer with an NCO content of about 12%. The reaction was carried out in a stoichiometric ratio (index 100). The reaction between the polyol A and isocyanate B components was carried out by stirring the two components at 1000 rpm with a Visco Jet stirrer unit for 10 seconds. After the end of the stirring process, the resulting reaction mixture (about 400 g) was poured into a 2 L wooden box and the cure characteristics were determined from the cream time and tack-free time.

[0141] The activity of TiPOSS was found to be comparable to that of stannous octoate. Foams obtained from reactions with TiPOSS have lower densities. Strength properties and indentation hardness are correspondingly lower. 5.) Overall conclusion / use a) Use of TiPOSS in the preparation of SPUR prepolymers

[0142] The significant improvement in the reaction described in the reaction between DMC polyols and IPDI can be used for the commercial production of SPUR (hybrid polymers). Here, it can be expected that it will be possible to use significantly less catalyst (1 / 5 to 1 / 10) and / or lower temperatures (<80°C) and / or shorter reaction times. General Additionally, the formation of by-products in this formulation results in an undesirable increase in viscosity, thus allowing for individual improvements in reaction regimes and product quality, including lower product viscosity (of great importance to formulators). b) Preparation of KOH-based PU prepolymer using TiPOSS

[0143] The formation of prepolymers resulting from the reaction of KOH-based polyols and aliphatic and aromatic isocyanates can be effected using significantly less TiPOSS catalyst (1 / 5-1 / 10) and / or lower temperatures (<80°C) and / or shorter reaction times. Since the formation of by-products in this preparation leads to an undesirable increase in viscosity, it therefore seems reasonable that individual improvements of the reaction regime and product quality are possible. c) Use of TiPOSS in two-component clear encapsulation systems and PU varnishes based on HDI and other aliphatic isocyanates

[0144] The use of TiPOSS as a catalyst increases the cure rate of two-component polyurethane clear encapsulation systems and PU varnishes. The increase in molecular weight improves the mechanical properties of the varnish and the encapsulation compounds, respectively. d) Use of TDI Foam / TiPOSS in the Production of Slabstock Foams

[0145] In the production of TDI-based slabstock foams, as in all other applications specified under 5.), the use of TiPOSS as catalyst makes it possible to avoid the use of tin compounds, which are harmful to health, without any loss of product quality. e) FIPFG (Field Applied Foam Gasket) - Sealant Foam

[0146] The production of two-component polyurethane systems in the case of the FIPFG process based on TiPOSS-catalyzed curing is particularly advantageous since the curing process is accelerated by the higher reactivity of TiPOSS compared to DBTL. The polyurethane products can furthermore be produced without health-hazardous tin compounds, which is particularly important for the production of sealant materials in the medical sector, kitchen applications, etc. f) Use of TiPOSS in Moisture-Curable One-Component Isocyanate-Terminated Prepolymers

[0147] The curing of one-component isocyanate-terminated prepolymers can be accelerated by the use of TiPOSS. It is possible to avoid the use of tin compounds, which are harmful to health. This is particularly relevant when these prepolymers are used as adhesives for conventional floor coverings, since it is possible to avoid the possibility of contamination with even small amounts of tin through the skin of the feet.
