Low temp. impact resistant polycarbonate moulding compsn. - contg. polycarbonate based on substd. di:hydroxy:di:phenyl:cycloalkane and grafted rubber plus hydrogenated nitrile rubber or EVA

摘要

Thermoplastic moulding compsns. comprise (A) 20-97 wt.% of a polycarbonate based on a substd. dihydroxydiphenylcycloalkane of formula (I); (B) 3-80 wt.% of a graft copolymer with a rubber substrate and resin-forming grafting monomers; and (C) 1-50 wt.% of either (i) a hydrogenated statistical nitrile rubber or (ii) an EVA copolymer R1 and R2 = H, halogena, 1-8C alkyl, 5- or 6C cycloalkyl, 6-10C aryl or 7-12C aralkyl; m = 4,5,6 or 7; R3 and R4 = H or 1-6C alkyl opt. being different for each individual X; and X = C, with the proviso that at least one C has R3 and R4 both = alkyl.
