Abstract
Description
Background of the Invention
[0001] field. The present invention generally relates to the field of adding light stabilizer compositions to certain organic materials that protect against the harmful effects of prolonged exposure to UV radiation. More particularly, the disclosure relates to stabilizer compositions having certain UV light stabilizers and their use in various materials, such as polymer resins, to achieve improved service characteristics.
[0002] 2. Related technical descriptions. Many organic materials are known to degrade through several mechanisms, including exposure to electromagnetic radiation, such as sunlight and other sources of ultraviolet ("UV") radiation and heat. For example, as a result of prolonged exposure to the sun, polymeric materials such as plastics often discolor, lose gloss and mechanical properties, and / or become brittle. Consequently, numerous technologies have been developed for materials, such as UV light absorbers and various other stabilizers, that are capable of inhibiting this degradation in these materials.
[0003] In particular, UV light absorbers such as benzotriazoles and benzophenones were initially used to stabilize polymeric materials and protect such materials from degradation upon exposure to UV light. Later, hindered amine light stabilizers ("HALS") were found to be more effective than UV light absorbers ("UVAs") at scavenging free radicals formed in polymeric materials upon exposure to UV light. Consequently, the combined use of HALS and UV light absorbers is conventionally used to stabilize polymeric materials.
[0004] The use of UVA, either alone or in combination with HALS, to stabilize polymers (such as coatings and plastics) against weathering due to the direct or indirect effects of heat and UV radiation remains an active area of research. For example, U.S. Patent Nos. 4,619,956; 4,740,542; and 5,760,228 disclose compositions and / or methods for stabilizing polymer films, coatings, or molded articles against the effects of light, humidity, or oxygen by incorporating aryl triazines and HALS into the polymers. It is further disclosed that such triazines, when combined with certain HALS, exhibit enhanced stabilization due to a synergistic effect.
[0005] The synergistic combination of stabilizer compositions is further demonstrated by U.S. Pat. No. 6,051,164, which discloses that polyolefins containing certain ratios of HALS (having a molecular weight of at least 500 Da) and o-hydroxyphenyl triazine provide superior performance properties over those polyolefins containing either a single stabilizer or both a HALS and a triazine, but not in a synergistic ratio. Similarly, U.S. Pat. No. 6,843,939 discloses synergistic UV stabilizing additive blends comprising o-hydroxyphenyl triazine, HALS, and a hindered hydroxybenzoate, and providing improved performance over either a single stabilizer or a combination of only two of these stabilizer additives.
[0006] Furthermore, while most stabilizer compositions are intended to reduce or prevent degradation caused by heat, such stabilizer compositions typically do not produce the desired results. Frequently, stabilizer compositions useful for reducing or preventing degradation caused by heat are hindered or abandoned altogether due to the resistant effects when combined with compounds useful for absorbing UV light.
[0007] It is further known that the specific function of organic materials such as polymer resins can be realized by some additives and these polymer resins blends.For example, in some cases, it is desirable that the surface interface of modified polymer materials is to produce the sliding or lubricity of multiple related surface effects such as improvement, reduction, or lubrication of processing equipment.In some cases, it is also possible to desirably modify the polymer surface to improve the release of adhesive and promote the demoulding or adhesion of other materials from the polymer composition surface.In other cases, it is desirable to have good clarity and optical properties and to resist the polymer film of fogging.The various prior art additives that are classified as anti-caking additives, slip aids, friction modifiers, antifogging agents, antistatic agents and demoulding aids have been used for attempting to provide these attributes to different types of organic materials.These different prior art additives are generally described as surface-active compounds (i.e. surfactants).
[0008] Higher levels of these additives, i.e., amounts that significantly reduce the hydrophobicity of the surface of a polymeric article (as measured by contact angle), are required to achieve these intended functions. Thus, when added at sufficient concentrations (typically at least 1% to 3% or more by weight based on the polymer), certain of these classes of additives can render the surface of a polymeric article containing one or more such additives less hydrophobic, thereby reducing the contact angle of water on the article's surface and imparting desired characteristics or properties. While the amount of surfactant additive required to reduce the contact angle can vary depending on the type of additive(s) and / or polymer resin used, the total amount of one or more such additives needs to be sufficiently high to impart the desired properties to the polymeric article. Read another way, regardless of the precise concentration of these classes of additives required, the contact angle of water at the surface of an article containing one or more such additives needs to be sufficiently low so that the desired properties (e.g., anti-fog or antistatic) are achieved. by, for example, Shlosman et al., Controlled migration of antifog additives from LLDPE compatibilized with LLDPE grafted maleicanhydride, Advanced Polymer Technologies ( Polym.Adv.Technol. ), Vol. 25, pp. 1484-91 (2014), has reported that the contact angle of water on articles containing these classes of compounds should be at or less than about 20°, and more typically less than 10°, in order to achieve the desired level of anti-fog properties / surface effects. However, the use of these higher levels of surfactant compounds required to achieve the desired surface effects results in higher costs and can also often lead to undesirable properties such as blooming and poor processability. Blooming is the process by which a polymeric article becomes oversaturated with the higher levels of surfactant compounds, resulting in the formation of an unsightly precipitate at the surface of the article.
[0009] Thus, synergistic combinations of stabilizer additives may still be found even though the compounds themselves may be known for use alone for a specific purpose, or used together in concentrations or ratios not previously disclosed or suggested for a specific purpose, and which do not result in undesirable performance characteristics such as blooming or poor processability of the organic material to which they are added.
[0010] The discovery of such synergistic stabilizer additives that significantly improve the performance characteristics of a variety of organic materials subjected to mechanical stress, or actions such as oxidation, chain scission, and uncontrolled recombination and crosslinking reactions (induced by photooxidation and heat) would be a useful development in the art and could be rapidly accepted in many industries requiring such stabilized materials. SUMMARY OF THE INVENTION
[0011] The foregoing and additional objects of the present invention are achieved according to the principles of the invention described herein, wherein the inventors have detailed the surprising discovery that certain classes of compounds, some of which are known in the art as surfactants useful at various concentrations for imparting anti-fog, antistatic, or slip properties to polymeric resins containing them, have a synergistic effect on the stabilizing properties of UV absorbers, particularly when combined with free radical stabilizers such as hindered amine light stabilizers, and are effective for stabilizing a variety of organic materials susceptible to the deleterious effects of prolonged exposure to heat and / or light (e.g., from electromagnetic radiation). For purposes of describing the present invention, these certain classes of additive compounds are referred to as "co-actives" throughout this specification and the claims. As used throughout this specification and the claims, the term "UV stabilizer" shall refer to the classes of ultraviolet ("UV") light absorbers (or "UVAs") or hindered amine light stabilizers ("HALS") described herein, either individually as a class or in combination with one another. Reference to UVAs or HALS alone refers only to the respective individual classes of compounds.
[0012] Organic materials, such as polymer resins, containing stabilizing amounts of these co-active agents described herein with UV stabilizers have enhanced performance characteristics even when used at lower loading levels. Additionally, when stabilizer compositions containing these co-active agents with UV stabilizers are used to make such films or blended with such polymers, other performance issues, such as blooming of the films or reduced processability of the polymers, are not encountered.
[0013] Thus, in a first aspect, the present invention provides stabilizer compositions having a stabilizing amount of an ultraviolet absorber selected from the group consisting of o-hydroxyphenyltriazine compounds; o-hydroxybenzophenone compounds; o-hydroxyphenylbenzotriazole compounds; benzoxazinone compounds; and mixtures thereof; and a stabilizing amount of a co-active agent, wherein the co-active agent is present in an amount from 1 wt.% to 99 wt.% based on the total weight of the stabilizer composition.

[0015] In another aspect, the present invention provides masterbatch concentrates having one or more stabilizer compositions as described herein and at least one organic material that is the same as or compatible with the organic material to be stabilized.
[0016] In yet another aspect, the present invention provides a method for forming a stabilized article by combining an organic material that is subject to degradation and / or discoloration due to the effects of light, oxygen, and / or heat (e.g., from prolonged exposure to electromagnetic radiation) with one or more stabilizer compositions or masterbatch concentrates as described herein, and shaping the organic material into an article, thereby forming the stabilized article. Thus, also provided are articles made from the organic material to be stabilized and a stabilizing amount of one or more stabilizer compositions or masterbatch concentrates as described or claimed herein.
[0017] The present invention also provides methods for protecting organic materials from the deleterious effects of light and heat due to exposure to UV radiation by combining the organic material with a stabilizing amount of one or more stabilizer compositions or masterbatch concentrates described or claimed herein.
[0018] Finally, the present invention also provides kits having one or more stabilizer compositions or components thereof or one or more masterbatch concentrates as described or claimed herein in one or more containers for stabilizing organic materials subject to thermal and / or oxidative degradation due to light and heat.
[0019] These and other objects, features and advantages of the invention will become apparent from the following detailed description of the different aspects of the invention taken in conjunction with the accompanying drawings and examples. BRIEF DESCRIPTION OF THE DRAWINGS
[0020] In order that the above-described features of the present invention may be understood in greater detail, a more particular description of the invention may be had by reference to embodiments, some of which are illustrated or captured in the accompanying drawings. It should be noted, however, that these drawings represent only certain embodiments of the invention and are not to be considered limiting of its scope, as the invention may admit to other equally effective embodiments.
[0021] Figure 1A-1B is related to the data provided in 7-(5) and 7-(6) of Table 7A and shows images of polypropylene substrates exposed to weathering for 800 hours. (A) UV-3346 (HALS) (available from Cytec Industries, Inc., Woodland Park, NJ) and 0.01 wt.% of Polypropylene substrates stabilized with UV-1164 (o-hydroxyphenyltriazine) (available from Cytec Industries, Inc., Woodland Park, NJ) showed surface cracking (i.e., failure) at 800 hours; (B) with 0.09 wt.% of UV-3346 (HALS); 0.01 wt.% Uv-1164 triazine; and 0.10 wt.% S2 (diethylene glycol octadecyl ether) (available from Sigma Aldrich Corp., St. Louis, Mo.) stabilized polypropylene substrates showed a smooth surface at 800 hours. Each substrate is shown at 40x magnification.
[0022] Detailed description of certain embodiments of the invention
[0023] As summarized above, the present invention is based on the discovery that additive compounds currently known in the art, used at certain concentrations to impart various performance functions (e.g., anti-fog, antistatic, or slip properties) to polymeric resins or articles containing them, have a synergistic effect on the stabilizing properties of UV absorbers and are effective for stabilizing a variety of organic materials susceptible to deleterious effects caused by exposure to UV light, heat and / or oxidation - even at concentrations lower than those typically used to achieve other performance functions exemplified in the prior art.
[0024] Materials containing the stabilizer compositions described herein provide such improved performance characteristics against exposure to electromagnetic and thermal radiation, as compared to prior art stabilizer compositions, a result that is completely unexpected and surprising. While only certain classes of these additive compounds are described herein as having a synergistic effect with the stabilizing properties of UV stabilizers on organic materials, the present invention encompasses any additive or mixture of additives that acts synergistically with these UV stabilizers to stabilize organic materials against the harmful effects of UV light, heat, and / or oxidation. In some cases, these classes of additive compounds affect the surface tension on articles containing the stabilizer compositions according to the present invention, wherein the contact angle of water at the surface of the article is greater than 20°. Preferably, the contact angle of water at the surface of an article containing the stabilizer composition as described herein is greater than 25°.
[0025] Thus, as used throughout this specification and in the claims, the term "co-active agent" shall refer to any such additive compound, or mixture of additive compounds (but not necessarily surfactants), that acts synergistically with a UV absorber (alone or in combination with a hindered amine light stabilizer) to help stabilize organic materials from the harmful effects of UV light, heat, and / or oxidation. Stabilizer compositions containing these co-active agents are optionally capable of providing a contact angle with water at the surface of an article containing the stabilizer composition according to the present invention of greater than 20°.
[0026] Stabilizer composition. The stabilizer composition according to the invention is suitable for stabilizing various organic materials that are subject to mechanical stress, discoloration, or effects such as oxidation, chain scission, and uncontrolled recombination and crosslinking reactions (induced by photooxidation), and can be incorporated into such organic materials to protect them from these harmful effects, or it can be used as a UV filter layer or be used in a UV filter layer to prevent UV radiation from reaching the organic material or articles produced with the organic material.
[0027] The stabilizer composition according to the present invention can be easily combined with the organic material to be stabilized by any suitable method known to those skilled in the art, or vice versa. As used herein, the term "combined" or "combining" with respect to the stabilizer composition and the organic material to be stabilized includes all manner and / or techniques known to those skilled in the art for intermixing, blending, integrating, mixing, or blending two or more substances. In certain embodiments, the components of the stabilizer compositions can be combined with the material to be stabilized by at least one technique selected from extrusion, granulation, grinding, and molding. In other embodiments, the combination can be performed by at least one of melting, dissolution in a solvent, direct mixing, and dry mixing.
[0028] The stabilizer composition according to the present invention and the optional additional co-stabilizer and / or co-additive can be incorporated into the organic material to be stabilized by known methods, such as dry blending in powder form or wet mixing in the form of a solution, dispersion or suspension (e.g. in an inert solvent, water or oil). Such stabilizer compositions are preferably non-aqueous. The co-active agent and UV stabilizer used in the stabilizer composition and the optional additional co-stabilizer and / or co-additive can be incorporated into the organic material to be stabilized by any suitable method known to those skilled in the art and include, for example, before or after molding, or also by applying the dissolved or dispersed stabilizer mixture to the organic material to be stabilized, with or without subsequent evaporation of the solvent or suspension / dispersant. They can be added directly to the processing equipment (e.g., extruder, internal mixer, kneader, etc.) as a dry mixture or powder or as a solution or dispersion or suspension or melt.
[0029] The individual components of the stabilizer composition according to the invention and optionally further costabilizers and / or co-additives can also be incorporated into an organic material, such as a polymer, for example before, during, or immediately after the polymerization of the corresponding monomers, or at some point before crosslinking. In this context, the stabilizer composition according to the invention can also be incorporated into the organic material to be stabilized (in pure form (i.e., neat and directly as a resin)) or encapsulated in a wax, oil or polymer.
[0030] The various additives can also be pre-blended (i.e., mixed together) for simple addition to the organic material to be stabilized. The individual components of the stabilizer composition and optionally further costabilizers and / or co-additives can also be sprayed onto the organic material to be stabilized. They can dilute other conventional additives or their melts so that they can also be sprayed onto the material to be stabilized together with these additives. In the deactivation process of any polymerization catalyst, addition by spraying can be particularly advantageous because the released steam can be used to deactivate the catalyst. In the case of spherically polymerized polymers, for example, it may be advantageous to apply the individual additive components of the stabilizer composition, optionally together with other additives, by spraying.
[0031] Thus, in one aspect, the present invention provides stabilizer compositions having a stabilizing amount of an ultraviolet light absorber (UVA) selected from the group consisting of an o-hydroxyphenyltriazine compound; an o-hydroxybenzophenone compound; an o-hydroxyphenylbenzotriazole compound; a benzoxazinone compound; and mixtures thereof; and from 1 wt.% to 99 wt.% of a co-active agent based on the total weight of the stabilizer composition. In certain embodiments, the stabilizer compositions may further comprise a stabilizing amount of a hindered amine light stabilizer (HALS).
[0032] Reference is made to the stabilizer compositions of the present invention containing the co-active agent and UV stabilizer as a "neat" composition (i.e., without dilution or admixture with other substances), which stabilizer composition may optionally contain additional UV stabilizers, co-stabilizers and / or co-additives. However, in another aspect, the present invention also includes masterbatch concentrates having a stabilizer composition as described herein in any embodiment and an organic material that is the same as or compatible with the organic material to be stabilized. In this context, the organic material that is the same as or compatible with the organic material to be stabilized acts as a carrier vehicle for the stabilizer composition described herein, which is then blended with the organic material to be stabilized. Although the amount of stabilizer composition present as part of the total masterbatch concentrate will vary based on, for example, the type of material to be stabilized and / or its end-use application, in some embodiments, the stabilizer composition will be present in an amount from 10 wt.% to 90 wt.% based on the total weight of the masterbatch concentrate. In other embodiments, the stabilizer composition may be present from 30 wt.% to 80 wt.%; or from 40 wt.% to 75 wt.% of the total weight of the masterbatch concentrate.
[0033] In yet another aspect of the stabilizer compositions described herein, the present invention provides kits having at least one stabilizer composition as described herein or a co-active agent of such a stabilizer composition and a UV stabilizer and / or an organic material to be stabilized in one or more containers. The kits may include one or more components of at least one stabilizer composition according to the present invention, at least one material to be stabilized (e.g., a polymer composition such as a polyolefin), and optionally at least one additional co-stabilizer and / or co-additive, each packaged or formulated separately. In other embodiments, the kits may have one or more components of at least one stabilizer composition according to the present invention, at least one material to be stabilized, and optionally at least one additional co-stabilizer and / or co-additive (packaged or formulated in combination).
[0034] Thus, one or more components of a stabilizer composition as described herein (e.g., co-active agent + UVA; co-active agent + HALS, or co-active agent + UVA + HALS) can be present in a first container, and the kit can optionally include one or more components of the stabilizer composition and / or the material to be stabilized in a second or additional container. The one or more containers can be placed within a package, and the package can optionally include instructions for use or mixing in the form of a label or website address on the package or in the form of an insert included in the packaging of the kit. The kit can also include additional components or other means for use or mixing these components, as well as solvents or other means for formulation.
[0035] Co-active agent. As discussed above, a co-active agent refers to any additive or mixture of additives that acts synergistically with a UV absorber (optionally in combination with a HALS) to effectively stabilize an organic material against the deleterious effects of UV light, heat, and / or oxidation. In certain embodiments, the combination of the co-active agent and the UV absorber (and optionally in combination with a HALS) does not significantly reduce the surface tension properties of the organic material, such that an article made therefrom has a contact angle with water at the surface of such article greater than 20°. While certain of these co-active agents are known in the art (at certain concentrations for imparting specific properties to the materials in which they are included), it has heretofore been unknown that these co-active agents provide a synergistic effect on the stabilizing properties of UV absorbers, optionally in combination with free radical stabilizers such as hindered light amines, and, as demonstrated for the first time, are effective in stabilizing a variety of organic materials susceptible to the deleterious effects of exposure to heat and / or light (e.g., from electromagnetic radiation).
[0036] In certain embodiments, the stabilizing amount of a co-active agent for use in the stabilizer compositions described herein can be selected from the group consisting of: C 12 -C 60 Alcohols; alkoxylated alcohols or monoalkyl ethers thereof; alkoxylated esters of fatty acids; sorbitan esters or ethoxylates thereof; mono- or polyglycerol esters having from 1 to 20 glycerol units or alkoxylates thereof; alkoxylated fatty amines, their esters or salts thereof; sugar esters; alkoxylated fatty amides; alkoxylated natural oils; ethylene oxide / propylene oxide copolymers; and mixtures thereof.
[0037] In some embodiments, the co-active agent may be C 12 -C 60 Alcohol, which can be monohydric, polyhydric or a mixture of the two. When the co-active agent is a monohydric alcohol, the monohydric alcohol can be C 12 -C 36 And preferably C 12 -C 22The alkanol is a primary, secondary, straight chain, branched chain, or cyclic (i.e., cycloalkanol) alcohol.

[0038] In the same or other embodiments, the co-active agent can include an alkoxylated alcohol or a monoalkyl ether thereof. In certain embodiments, the co-active agent can be an alkoxylated alcohol or a monoalkyl ether thereof according to formula (III):
[0039] R-(OCHR'CH2) y -OR” (III)
[0040] wherein R is a hydrocarbon group having from 12 to 60 carbon atoms; R′ is selected from H or a C1-C4 alkyl group; R″ is selected from H or a hydrocarbon group having from 1 to 10 carbon atoms; and y is an integer from 1 to 100.
[0041] The term "hydrocarbyl" as used herein is a general term for aliphatic, alicyclic and aromatic groups having a full carbon skeleton and consisting of carbon and hydrogen atoms. In some cases, as defined herein, the one or more carbon atoms constituting the carbon skeleton may optionally be replaced or interrupted by a specific atom or group of atoms such as by one or more heteroatoms in N, O and / or S. Examples of hydrocarbyl include alkyl, cycloalkyl, cycloalkenyl, carbocyclic aryl, alkenyl, alkynyl, alkylcycloalkyl, cycloalkylalkyl, cycloalkenylalkyl and carbocyclic aralkyl, alkaryl, aralkenyl and aralkynyl.
[0042] Such hydrocarbyl groups may also be optionally substituted with one or more substituents as defined herein. The examples and preferences indicated below also apply to each of the hydrocarbyl substituents or hydrocarbyl-containing substituents referred to in the various definitions of substituents for compounds of the formulae described herein, unless the context indicates otherwise.
[0043] Preferred non-aromatic hydrocarbon groups are saturated groups, such as alkyl and cycloalkyl groups. In general, and by way of example, these hydrocarbon groups may have up to one hundred carbon atoms, unless the context otherwise requires. Hydrocarbon groups having from 1 to 60 carbon atoms are preferred, with hydrocarbon groups having from 1 to 36 carbon atoms being more preferred. Within the subset of hydrocarbon groups, specific examples are C 12-60 Hydrocarbon, C 12-30 Hydrocarbon, C 12-22 Hydrocarbon, C 1-10 Hydrocarbon, or C 1-4 Hydrocarbyl, although selected from C1 to C 60 Any individual value, range, or combination of values for hydrocarbyl is contemplated by the inventors as if specifically recited herein.
[0044] As indicated by the context in which it is used herein, the term "alkyl" is intended to include straight chain, branched chain or cyclic hydrocarbon structures and combinations thereof. Lower alkyl refers to an alkyl group having from 1 to 6 carbon atoms. Examples of lower alkyl groups include methyl, ethyl, propyl, isopropyl, butyl, sec-butyl and tert-butyl, pentyl, hexyl, or cyclohexyl, etc. Preferred alkyl groups include C 36 or below C 36 Those.
[0045] Thus, in certain embodiments, R of formula (III) can be an alkyl group having from 12 to 30 carbon atoms. In other embodiments, R can contain from 12 to 22 carbon atoms, and ideally from 12 to 18 carbons, or 12 to 15 carbons.
[0046] As used herein, the term "alkoxy," "alkoxyalkyl," or "alkoxylated" refers to a group of from 1 to 20 carbon atoms in a linear, branched, or cyclic configuration, or a combination thereof, which is either attached to the parent structure through an oxygen atom or incorporated into the backbone of the moiety via an oxygen atom. Examples include methoxy, ethoxy, propoxy, isopropoxy, butoxy, cyclopropyloxy, cyclohexyloxy, and the like.
[0047] Thus, in certain embodiments, or in embodiments similar to those previously described with respect to formula (III), R' can be methyl or ethyl. In still other embodiments, R' can be H.
[0048] Thus, in certain embodiments, the stabilizer compositions according to the present invention may include a co-active agent that may be alkoxylated with one or more alkoxides. In some embodiments, the co-active agent according to formula (III) may be ethoxylated. In other embodiments, the co-active agent according to formula (III) may be propoxylated. In the same or other embodiments, the co-active agent according to formula (III) may include a mixture of ethoxylated and propoxylated alcohols, or may be both ethoxylated and propoxylated alcohols.
[0049] While the degree of alkoxylation (i.e., the number of ethoxy and / or propoxy groups in the co-active agent) can vary among co-active agents, the degree of alkoxylation contemplated by the inventors for the co-active agents described herein ranges from 1 to 100. In certain embodiments, the degree of alkoxylation given by "y" of the co-active agent according to formula (III) can range from 1 to 75. In other embodiments, the degree of alkoxylation can range from 2 to 25, or from 2 to 12.
[0050] In any of the above-discussed embodiments for the co-activator according to formula (III), the co-activator can be an alcohol, such as when R″ is H. In other embodiments, the co-activator can be a monoalkyl ether derived from such an alcohol, for example when R″ is a hydrocarbyl group having from 1 to 10 carbon atoms. In one embodiment wherein the co-activator is a monoalkyl ether according to formula (III), R″ is methyl.

The conditions during injection molding were as follows: nozzle temperature: 230°C; injection pressure: 60, shot size: 14.5. The additives were used as received, except that some of the ethoxylated alcohols were methylated according to the following method.
[0338] for UV weathering The samples were exposed to QUV-313 under ASTM G-154 test conditions. Gloss (60°) values were measured at set exposure intervals. High gloss values indicate a smooth surface with no surface cracks or blooming. When samples began to show surface cracks, they were considered to have failed.
[0339] for Physical properties Five tensile bars were tested for each data point on an Instron Engineering Company tensile testing machine (Model TTB). The average physical properties of the five test samples were measured using ASTM D638 Type-5 method. The crosshead speed of the tensile testing machine was 2 inches (0.508 cm) per minute. If the samples retained less than 50% of their original physical properties, they were considered to have failed.
