摘要 |
<p>An improved high impact, low warp polymer blend comprises a polyalkylene terephthalate resin, an organopolysiloxane-polycarbonate block copolymer and a CaCO3 filler. Pref. copolymers are of formula (where A is p-phenylene substd. by 4 E gps.; X is 1-1000 (2-100); n is 1-100 (5-40); a is 1, 1-100; m is 1; z is 1-1000 (5-12); each E is H, lower alkyl or halogen; R is H or opt. unsatd. (halo)alkyl; R1 is opt. unsatd. (halo)alkyl or cyanoalkyl), n and a are number averages. Blends are used as moulding materials.</p> |
