| titleOfInvention | Improvements in thermoplastic compositions |
| abstract | A thermoplastic composition comprises up to 99% (by weight) of a polymer of vinyl chloride and/or vinylidene chloride and at least 1% of a copolymer of 88 to 99% of a polymerisable ethylenically unsaturated ester and 20 to 1% of an N-vinyl lactam. The chloride polymer may be a homopolymer or copolymer in any ratio of vinyl and vinylidene chlorides or a copolymer based thereon and containing only a minor proportion of other monomers. Polymerisable esters specified are acrylic and methacrylic esters of C1-12 alcohols, e.g. methyl, ethyl, butyl and dodecyl acrylate, and ethyl and butyl methacrylate; and vinyl esters containing up to 12 carbon atoms, e.g. vinyl propionate and butyrate. Suitable lactams are N-vinyl-pyrrolidone,-epsiloncaprolactam, and -omega-caprylic lactam. The copolymer may also contain other vinyl compounds, e.g. styrene, vinyl ethers, vinyl chloride, and vinyl methyl ketone. The copolymers may have varying K values, e.g. 20 to 30 ; 60 to 80 ; or below 15 ; they are soluble in aromatic hydrocarbons esters, ketones, simple alcohols, and gasoline hydrocarbons ; they are compatible with cellulose esters, alkyd resins and urea resins as well as vinyl and vinylidene chloride polymers. Examples comprise :-(i) 80 parts PVC and 20 parts 98/2 butyl acrylate/N-vinyl-caprolactam (ii) 100 parts of an 85/15 vinylidene chloride/vinyl chloride copolymer and 10 parts of a 90/10/5 butyl acrylate/N-vinyl 2-pyrrolidone/cyclohexene copolymer; and (iii) PVC and a 95/5/5 ethyl acrylate/N-vinyl 2-pyrrolidone/allyl alcohol copolymer. |
