Abstract

The ionomer and its precursor olefin / unsaturated acid copolymers are rendered antistatic by the inclusion of polyalkoxycylate or alcohol polyoxyalkylates, particularly ethoxylated or ethoxylated / propoxylates. Particularly useful alcohol polyalkoxylates are of formula (I): Rl (0A) n.OR1, wherein Rl is C6 to C22 alkyl or alkenyl, R2 is hydroxyl, OA is oxyalkylene, preferably oxyethylene, oxypropylene or an oxyethylene combination. and oxypropylene, and n is from 2 to 50. The antistatic effect is good even in the presence of slip agents such as fatty acid amides.

Description

POLYMERIC ANTIESTETIC COMPOSITIONS DESCRIPTION OF THE INVENTION This invention relates to the use of surfactant compounds and compositions, particularly those based on alcohol alkoxylates, as additives of antistatic agents in polymer resins and particularly in copolymers of olefins, notably ethylene and ethylenically unsaturated acids, notably (meth) acrylic acid and especially in ionomers. Ionomers are thermoplastic polymeric plastic materials that contain both covalent and ionic bonds. Their properties are substantially influenced by ionic bonding by providing a combination of properties that make them attractive for certain end uses, especially in films and extrusion coatings. Chemically they are typically copolymers of olefins, such as ethylene, and monomers containing an acidic group, such as ethylenically unsaturated acids, particularly acrylic and methacrylic acids, which have at least some of their acid functions neutralized with suitable bases, particularly a base of sodium, zinc or lithium. The interaction between the carboxylate groups and the metal ions of the base provides ionic "crosslinks" between the polymer chains. These ionic "crosslinks" provide strength, stiffness and firmness to the polymer and still allow for melt processing as described, for example in Kirk Othmer Encyclopedia of Chemical Technology, 4th edition, volume 14, pages 818 and 819. Despite the ionic component of Their chemical bonding, ionomers are typically good electrical insulators tend to be susceptible to the generation and retention of static electrical charges. In fact, some uses of ionomers, for example, in non-electrical explosive ignition systems, are based on these properties. It has proved difficult to find good antistatic agents for ionomers. Previous attempts to provide antistatic agents for ionomers include the use of sorbitan esters, especially the combination of sorbitan monooleate and ethoxylated alkylphenols proposed in US 5037875 A (DuPont) and in simple systems, these materials provide certain antistatic properties. However, the inclusion of additives typically used in the production of films or coatings of ionomers, in particular slip additives such as fatty acid amides, or exposure to typical temperatures in the manufacture of coatings on substrates, for example, by coating extrusion or coextrusion, which results in an anti-static operation greatly diminished. We have tried other conventional polymeric antistatic agents (additives) which include monoesters of glycerol fatty acid such as glyceryl monostearate, and ethoxylated amines, and have been found to be ineffective as antistatic additives in ionomers. To date, there are no commercially available antistatic agents for ionomers that are satisfactory and effective in such practical end-uses. The present invention is based on the discovery that good antistatic properties can be obtained in ionomers and copolymers of olefins, notably ethylene, and ethylenically unsaturated acids, notably (meth) acrylic acid) which can be used as precursors for ionomers) when using alcohol polyalkoxylates and / or their derivatives. Accordingly, the present invention provides an ionomer and / or a copolymer of an olefin and an ethylenically unsaturated acid containing one or more polyoxyalkylates or polyalkoxylates of alcohol in an amount to provide effective antistatic activity. The invention includes the use of alcohol polyalkoxylates as antistatic agents in ionomers, and / or copolymers of olefins and ethylenically unsaturated acids, and in particular of ionomers manufactured as films which can be self-supporting films or film coatings on substrates. For convenience, the term "polymer resin" is used to refer to ionomers, olefin / ethylenically unsaturated acid copolymers, and combinations thereof.

The alcohol alkoxylates used in the invention are typically alkoxylates of fatty alcohols, particularly alcohols having a fatty chain of at least about 6 carbon atoms long. The shorter chain alcohols generally have alkoxylates that are not sufficiently compatible with, or that are very easily removed from the polymer resin to be satisfactory as antistatics. The carbon chain in the alcohol can be as large as 30 carbon atoms. However, the carbon chain in the alcohol is usually not longer than about 22 carbon atoms because alcohols with such chains are not readily available and their use does not seem to provide any particular advantage. The polyalkoxylate chain is logically composed of oxyethylene and / or oxypropylene units with the chain containing at least 2 and typically no more than about 50 oxyalkylene units since such longer chains do not appear to provide any particular advantage. Particularly desirable alcohol polyalkoxylates for use in the present invention are those of the formula (I): R1 (OA) n .R2 (I) wherein R1 is a C6 to C22 alkyl or alkenyl group; R2 is a hydroxyl group; OA represents an oxyalkylene group, which may differ along the polyoxyalkylene chain, and which is desirably an oxyethylene group (OE = -OCH2CH2-), an oxypropylene group (OP = -OC3Hs-) or a combination of oxyethylene groups and oxypropylene; and n is from 2 to 50. The group R1 is a relatively hydrophobic group which provides satisfactory compatibility with the mainly polyolefin base polymer. Within the range of C6 to C22 given above in formula (I), R1 is desirably an alkyl group of C8 to C20, especially a C9 to C18 alkyl.

Typically, the fatty alcohols, which contain such alkenyl or alkyl groups, which are used as the starting materials for producing the alkoxylates used in the invention are derived from natural sources or distillation cuts and typical commercially available materials are mixtures of compounds with a dispersion of chain lengths. The carbon chain lengths referenced in the above are average chain length values. In the formula (I) in the polyoxyalkylene chain, the OA group or groups are desirably oxyethylene and / or oxypropylene groups. In particular, the chain is a polyoxyethylene chain or a copolymer chain containing both oxyethylene and oxypropylene groups. Generally, we have found that homopolymer polyoxyethylene chain compounds provide antistatic effects somewhat more rapidly than corresponding compounds having copolymer chains containing oxypropylene groups, for example, both oxyethylene and oxypropylene groups, and this effect is more pronounced as greater is the proportion of oxypropylene groups. We believe that this effect is related to the speed with which the compounds migrate in the polymer resin - generally, the faster the migration, the faster the antistatic effect occurs. Since more mobile compounds can be removed from the polymer resin by volatilization, washing or abrasion, this effect can be exploited by using a relatively mobile compound to obtain antistatic effects quickly, and a relatively less mobile compound to provide an effect with greater duration, to compensate for the loss of the antistatic during the use of the polymer resin substrate. In formula (I), the repeated chain length, n, of the polyoxyalkylene chain will desirably be from 2 to 30, particularly 3 to 25. Of course, n is an average value which may be non-integral. When the chain is a homopolymer polyoxyethylene chain, it is desirably 3 to 20, especially 3 to 15. When the chain is a copolymer chain containing oxyethylene and oxyiprene units, n is desirably 5 to 25, especially 5 to 20. In such copolymer chains, the ratio of oxyethylene units to oxypropylene units is typically from 1: 2 to 25: 1, especially 1: 1.5 to 15: 1. Particularly desirable compounds of the formula (I) are those of the formulas (la): R1 (OE) k. (OP)! . R2 (the) wherein R1 is an alkyl group of C10 to C20; R2 is a hydroxyl group; OE represents an oxyethylene group, - OP represents an oxypropylene group; k is from 3 to 20, 1 is from 0.2 to 10, and the polyoxyalkylene chain of the OE and OP units is a block or random copolymer chain. The value of k is typically from 5 to 15, especially 5 to 10, and 1 is typically from 0.2 to 8, especially 0.3 to 5. The polymeric resin used in the invention is at least one ionomer and / or at least one copolymer of, and olefin, notably ethylene, with an ethylenically unsaturated acid, notably acid or (meth) acrylic acids. The ionomers desirable for use in this invention are based on copolymers of ethylene, with ethylenically unsaturated carboxylic acids, typically α, β-unsaturated acids having at least 3 and usually not more than 8 carbon atoms. Suitable examples include acrylic, methacrylic and itaconic acids. Commercially available ionomers are usually based on copolymers of ethylene with acrylic or methacrylic acid. The molar ratio of acid units is typically from 1.5 to 30%, more usually from 2 to 25%, particularly from 2 to 10%, of the combination of ethylene and acid units in the copolymer. In the ionomers, the acid groups in the copolymer are at least partially neutralized to incorporate metal ions into the polymer and, thus, form the ionomer structure. The metal ions of the neutralizing base are typically an alkali metal or alkaline earth metal or a metal of the zinc group. Most commonly the metal is sodium, lithium or zinc. We have obtained particularly good results with ionomers containing zinc and, consequently, the use of zinc in the ionomer forms a specific and desirable aspect of the present invention. The extent of neutralization in commercially available ionomers typically corresponds to values in the range from 10 to 90%, more usually from 15 to 30% of the carboxylic acid groups. The ionomers used in this invention typically have melt flow index (MFI) values up to 30 g.10 min "1, and usually not greater than 20 g.10 min" 1. We have obtained good results of ionomers that have MFI in the range of 0.1 to 10 g.10 min "1.

The manufacture of ionomers and their manufacture into films is described in the North American patents numbers 4248990, 3264272 and 4351931 of DuPont. Suitable ionomers for use in this invention include materials measured under the trademark Surlyn Trade Mark by DuPont, for example, Surlyn 1652 E, Surlyn 9520 and Surlyn 9910. The (non-ionomeric) copolymers that can be used in this invention generally have a Main structure chemistry similar to those used as precursors for ionomers, that is, they are usually copolymers of ethylene with C3 to C8 ß-unsaturated carboxylic acids, such as acrylic and methacrylic acids. Commercially available copolymers typically have a molar ratio of acid units from 1.5 to 30%, more usually from 2 to 25%, particularly 2 to 10% of the combination of ethylene and acid units, in the copolymer and having values MFI from 1 to 30, especially 2 to 15 g.10 min. "1 Suitable copolymers for use in this invention include materials measured under the trademark Nucrel by DuPont.The antistatic agents used in this invention can be incorporated into the polymeric resin and / or coating on one or more surfaces of the resin which is desired to become antistatic.The antistatic may be incorporated in the resin generally by conventional methods, typically by including the antistatic as a component in the resin formulation prior to molding ( see below below.) When used by coating on a resin surface, the antistatic can be sprayed, or coated, for example, by painting or by coating with a machine, such as a liquid or a solution in a suitable solvent or dispersed in a suitable diluent. When used, the solvent / diluent used will typically be relatively volatile so that it evaporates from the surface, leaving the remaining antistatic coated on the surface. Suitable solvents / diluents include water, low molecular weight organic solvents, for example alcohols such as methanol, ethanol or propanol or mixtures of hydrophilic organic solvents, such as the above alcohols, with water. The concentration of the antistatic in such solutions or dispersions will typically be from 0.1 to 20%, more usually from 0.5 to 5% by weight of the solution or dispersion. The surface of the coated polymer resin can be the entire exposed surface of the polymer resin or a selected surface which is desired to become antistatic. When used by coating on the polymeric resin substrate, the antistatic effect generally develops very rapidly (in the following minutes and usually as the coating dries). However, the antistatic effect may not last as long as when the antistatic additive is incorporated into the polymeric resin. We believe that two mechanisms contribute to this relatively short duration; the relative ease with which the antistatic additive (which is relatively hydrophilic) can be removed from the surface, especially by washing, and the absence of an antistatic additive deposit to replace such losses. However, such a coating can be used to fabricate polymeric resin surfaces of already manufactured antistatic material. Of course, it is possible to use both ways of using the antistatic additive and this can have the advantage of providing both fast and lasting effects. The amount of antistatic used in the polymer resin formulations according to this invention will be sufficient to provide an antistatic effect. When used to be incorporated into the resin, typically the minimum amount to be effective is about 0.2% by weight of the formulation, although the amount usually used will be at least 0.25%. The maximum amounts will typically be about 5.0% by weight of the formulation, and amounts greater than about 2.5% offer little additional benefit and are generally not used. We have obtained good results using amounts in the range of 0.5 to 2% by weight of the formulation. Therefore, the typical antistatic proportions used based on the polymer resin are:% by weight Broad 0.2 to 5 Desirable 0.25 to 2.5 Optimum 0.5 to 2 When used to be coated on the resin, typically the minimum amount to be effective is about 5 mg.m 2 (mg of alcohol alkoxylate per square meter of coated polymer resin article area). The amount used will usually be at least 10 mg.m "2. The maximum amounts usually do not exceed about 500 mg-m "2, and amounts greater than about 300 mg-m" 2 offer little additional benefit and will generally not be used. We have obtained good results using quantities in the range of 25 to 200 mg.m "2. The typical amounts of antistatic used per unit area of coated polymer resin are: mg.m "2 Wide 5 to 500 Desirable 10 to 300 Optimal 25 to 200 When the polymer resin has the alcohol alkoxylate antistatic agent incorporated therein and coated thereon if desired, for example, to provide both immediate and long-term antistatic performance, the amounts used in each treatment method will generally be within the corresponding intervals established above. The polymer resin compositions can, and typically will typically include other components typically as minor constituents usually totaling less than about 10% of the formulation, such as slip agents, antiblocking agents, antioxidants, especially UV stabilizers and / or other surfactant materials . Sliding agents are typically fatty acid amides, particularly C8 to C24 fatty acids, such as palmitic, oleic, stearic and erucic acids, for example erucamide (erucic acid amide) and oleylpalmitamide [(N-oleyl) palmitic acid amide ] As mentioned above in relation to fatty alcohols, the fatty acids from which such amides are made are usually available as mixtures, and this will be reflected in the composition of amides produced therefrom. The amount of slip agent used is typically in the range of 0.2 to 5%, more usually 0.5 to 2%, especially about 1% by weight of the total composition. Anti-blocking agents include those commonly used in this type of application, including highly finely divided silica, for example, what is called fumed silica. The amount used is typically from about 1000 to about 2000 parts per million by weight of the total composition. Suitable antioxidants are particularly UV stabilizers such as those sold under the tradenames Cyasorb UV 531 (Cyanamid), Tinuvin 770, Tinuvin 328 and Igranox 1010 (Ciba Geigy) and Sandovour EPU and Sandovour P-EPQ (Sandoz) and are typically used in amounts as recommended by the respective manufacturers, and generally in the range of 0.05 to 1%, particularly from 0.1 to 0.5% by weight of the total composition. UV antioxidant / stabilizer combinations can be used as is common in the art using total amounts of such additives typically from about 0.5 to 1% by weight of the total composition. Other antistatic additives, especially surfactant-type antistatic additives, can be included in the formulations, although we have not noticed any specific beneficial technical effect of this, as antistatic additives are significantly less good than the compounds used in this invention. The polymer compositions of this invention can be manufactured by conventional processing methods to include additives in melt-processable polymers, in particular by means of melt blending techniques, for example using Banbury mixers or extruders. For example, the antistatic agent additive can be melt-mixed into the polymer resin in an extruder, with the additive fed into the extruder premixed with the polymer resin, for example, by dry-mixed polymer resin granules with pulverized additive or by means of mixed granules of polymer resin and a master batch of additive in a similar polymer, or which is fed as a side stream in the extruder according to the molten polymer resin advances therethrough. The mixed material can be granulated, for example, by extrusion and cutting, for example, for subsequent manufacture in desired forms such as self-supporting film or for use in the formation of coatings on substrates, or it can be directly extruded as a self-supporting film. or it can be coated by extrusion on substrates. The master batches of the antistatic agent in the polymer resin can be made as granules by such methods and the polymer master base of the master batch need not be the same as the main polymer resin in the product formulation (but in practice , will be miscible with it). The polymer products of this invention that incorporate the antistatic additive can be used to make various products which are typically manufactured from the polymer resin materials. In particular, we expect the compositions of this invention to find application in self-supporting films for packaging, such as film coatings on, particularly sheets or tiles, substrates and in polymer resin formulations for casting and molding. When the polymer resin formulation including an antistatic agent according to the invention is used to make self-supporting films, the film will typically have a thickness from 10 to 100 μm, more usually from 10 to 50 μm, and especially from 15 to 50 μm. 30 / xm. The self-supporting film products can be used in packaging applications, particularly for wrapping articles and products susceptible to the generation and retention of static electric charge. When the polymer resin, especially ionomeric resin, the formation including an antistatic agent according to the invention for making film coatings on substrates, the coating film thicknesses will typically be from 1 to 100 μm, more usually from 2 to 50 μm. μm, and especially from 5 to 30 μm in thickness. Coated films can typically be applied to a variety of substrates, particularly film or sheet substrates, for example, paper, metal and polymer film and sheet polymer articles. Among the sheet polymer articles that can be particularly useful coated with the polymer resin formulation including an antistatic agent according to the invention are floor sheets and tiles made of polyolefin polymers. Such sheets and tiles have the objective in the market currently called as PVC-based products. The basic polyolefins used do not have wear surfaces hard enough to adapt to the technical performance of current PVC products and coating with polymer resins, especially ionomers, is considered as a way to provide them with stronger wear surfaces. The current lack of polymer resins, particularly ionomers incorporating satisfactory antistatic agents has decreased the development of such sheet and tile products. This application of the invention is considered as a subsidiary aspect separate from the invention which consequently includes sheets or tiles of floor material comprising a sheet or tile substrate of a polyolefin polymer material having on a surface subject to wear , a coating of an ionomer and / or a copolymer of an olefin and an ethylenically unsaturated acid containing one or more polyoxyalkylate or alcohol polyalkoxylates in an amount to provide effective antistatic activity. In making the substrates coated with polymer resin films that include the antistatic additives according to the invention, the film can be a single layer or more usually a multi-layer coating. For example, when the polymer resin is an ionomer, a three-layer structure can be used in which a base layer of ethylene / vinyl acetate copolymer (EVA) has a first layer of ionomer at the top. a relatively low concentration of antistatic additive, and a second layer on top of the first layer, and which is designed as the outer end layer and which withstands wear having a relatively high concentration of antistatic additive. The EVA copolymer is present to act as an adhesion layer between the ionomer and the sheet substrate. Such a three layer construction can conveniently be made by co-extrusion and the coated product can be manufactured by direct coextrusion coating or first by co-extruding a self-supporting film and then thermally bonding the film to the substrate. In final molding and casting applications, the antistatic agent will typically be used to prevent the accumulation of dust on molded or cast products. Since ionomers are especially used with high-grade packaging applications where the transparency of the packaging is considered critical, for example in the packaging of perfumes, the reduction or elimination of dust accumulation can be a very useful feature for such packaging. The following examples illustrate the invention. All parts and percentages are by weight, unless otherwise indicated.
