摘要： A thermoplastic composition comprises an intimate fusion blend of (a) 10 to 99 parts (by weight) of a rigid vinyl chloride polymer containing at least 80% vinyl chloride; (b) 90 to 1 parts of a substantially non-polar hydrocarbon elastomer and (c) 1 to 10% of either (i) a surfactant or (ii) a polar polymer containing halogen atoms or ester, carbonyl, amide, nitrile, sulphone or carboxyl groups. Specified comonomers which may be present in (a) are vinyl esters of C1- 18 organic acids; vinylidene chloride; nitriles and C1-8 alkyl esters of acrylic and methacrylic acids; and di-C1-8 alkyl esters of maleic and fumaric acids, (b) may be a homopolymer or interpolymer of two or more mono-olefines, e.g. ethylene, propylene or isobutylene, or a homopolymer of an acylic 1,3-diene, e.g. butadiene, isoprene, 2,3-dimethylbutadiene or piperylene, or a copolymer thereof with styrene or an alpha or nuclear alkyl styrene. The surfactants, (c)(i) contain a C8+hydrocarbon chain and a hydrophalic group e.g. a carboxyl, sulphoxy, amine, hydroxyl or amide group or polyethenoxy chain several examples being given from such classes as the sodium, calcium, barium, ammonium, amine and alkanolamine salts of fatty, resin and sulphonic acids of or sulphated esters of fatty alcohols; partial esters of polyhydric alcohols and fatty acids; condensates of ethylene oxide with such partial esters, fatty alcohols or acids, resin acids, or alkyl mercaptans or phenols; the conjugated polyoxypropylene-polyoxyethylene compounds of U.S.A. Specifications 2,674,619 and 2,677,700; quaternary ammonium salts; and amides. The polar polymer (c)(ii) may be a chlorinated ethylene polymer or copolymer, several conventional comonomers being mentioned; copolymers of a mixture of an acrylic ester or nitrile and a monoalkenyl aromatic hydrocarbon or halohydrocarbon which may be grafted on a diene rubber; copolymers of an acrylic 1,3-diene with an acrylic ester or nitrile, vinyl ketone or pyridine, dialkyl fumerate or nuclear-substituted acetyl styrene; polychloroprene; copolymers of sulphur dioxide and a C3- 12 olefine; and copolymers of ethylene or propylene with C1- 4 vinyl esters. Dibutyl tin dilauryl mercaptide is incorporated as stabilizer in exemplary compositions. The components may be blended dry or as aqueous dispersions but must in either case be ultimately heated above the fusion temperature of the vinyl chloride polymer. Specification 910,702 also is referred to.
