ALTERUNGSBESTAENDIGE THERMOPLASTISCHE FORMMASSEN MIT GUTER ZAEHIGKEIT.

摘要

Compsn. contains (A) 5-98 pts.wt. of a thermoplastic polycarbonate, (B) 2-70 pts. of a graft polymer of (B.1) 5-90 pts. of a mixt. of (B.1.1) 50-95 pts. of styrene, alpha-methylstyrene, ring-substd. styrene and/or methyl methacrylate, and (B.1.2) 50-5 pts. of (meth)acrylonitrile, methyl methacrylate, maleic anhydride and/or N-substd. maleinimide, on (B.2) 95-10 pts. of a rubber with particle size 0.05-10 microns, comprising (a) a core of a cross-linked silicone rubber and (b) a jacket of a cross-linked alkyl acrylate rubber, in ratio by wt. of (a):(b) of 0.1:99.9-90:10, and (C) 0-80 pts. of a thermoplastic copolymer of (C.1) 50-95 pts. of styrene, alpha-methylstyrene, ring-substd. styrene and/or methyl methacrylate, and (C.2) 50-5 pts. of (meth) acrylonitrile, methyl methacrylate, maleic anhydride and/or N-substd. maleinimide. (A) The component is a polydiorganosiloxane -polycarbonate block copolymer, opt. mixed with a bisphenol A polycarbonate. (D) The compsn. also contains stabilisers, pigments, mould release agents, flame-proofers and/or antistatics.
