| 摘要 |
Moulding compositions comprise a blend of (a) the polycarbonate of a di-(monohydroxy-phenyl)-substituted aliphatic hydrocarbon in which both hydroxyphenyl groups are attached to the same carbon atom of the hydrocarbon, and (b) a graft copolymer (1) polybutadiene and (2) a mixture of a vinyl cyanide and a vinyl aromatic hydrocarbon. Preferred proportions are 90 to 30 parts of polycarbonate to 10 to 70 parts of graft copolymer. The examples describe products obtained by blending the polycarbonate of 2,2-(4,41-dihydroxydiphenyl) with graft copolymers of styrene and acrylonitrile on polybutadiene. Specification 772,627 is referred to.
