Abstract
1304740 Polyester-aromatic vinyl polymer composition EASTMAN KODAK CO 16 July 1970 [17 July 1969] 34522/70 Headings C3P and C3R A polymer composition suitable for injection moulding comprises (a) a polyester of 1,4- butanediol, optionally mixed with up to 20 mole per cent of other diols, and terephthalic acid or a naphthalene dicarboxylic acid, optionally mixed with up to 20 mole per cent of another dicarboxylic acid, the polyester having an I.V. of 1À0 to 2À5 (0À25 g./100 ml. in 60/40 phenol/ tetrachloroethane at 25‹) and (b) a vinyl polymer comprising 1 to 40% by wt. of the composition and containing at least 50% by weight of styrene units, optionally substituted by Cl, phenyl or C 1 -C 4 alkyl in the ring and/or C 1 -C 4 alkyl at the α position. Other additives, e.g. crystallization promoters such as glass fibres, may also be present. The preferred components are polystyrene and poly(tetramethylene terephthalate) or poly(tetramethy. lene – 2,6 – naphthalene dicarboxylate). The examples also describe compositions in which the vinyl polymer is poly(dimethylstyrene), a copolymer of styrene with α-methylstyrene, methyl methacrylate, acrylonitrile, acrylonitrile and butadiene, or maleic anhydride or a copolymer of p-chlorostyrene and isobutylene. The use of polyesters modified by the inclusion of minor amounts of isophthalate, azelate or ethylene glycol units is also described. The compositions can be used to make injection moulded articles of improved strength and resistance to heat distortion, which may be further increased by annealing the articles.
