THERMOPLASTISCHE FORMMASSEN AUS VINYLCHLORIDPOLYMERISATEN UND PFROPFPOLYMERISATEN.

摘要

A thermoplastic moulding compsn. contains (A) a (co)polymer with at least 50 wt.% vinyl chloride, (B) a graft polymer obtd. by graft polymerising (B1) 50-85 pts.wt. of a mixt. of at least 2 of the monomers styrene, acrylonitrile, methyl methacrylate, and alpha-methylstyrene onto (B2) 50-15 pts.wt. of a (partly) cross-linked butadiene or acrylate rubber with particle dia. 0.08-1 microns, (C) a hydrogenated nitrile rubber with 5-28 wt.% CN gps. and more than 50% hydrogenation, and opt. (D) an uncross-linked rubbery ethylene or alkyl acrylate polymer, opt. copolymerised with up to 70 wt.% of vinyl acetate, acrylonitrile, methyl methacrylate, or CO, and opt. (E) a (partly) crosslinked rubbery ethylene or alkyl acrylate polymer, opt. copolymerised with up to 50 wt.% of vinyl acetate, acrylonitrile, methyl methacrylate or CO.
