Antistatic styrene polymer compositions
摘要:
A composition and articles, e.g. computer casings comprising, per 100 parts by weight: 99 to 60 parts of a styrene polymer (A), 1 to 40 parts of (B)+(C), (B) being a copolymer containing polyamide blocks and polyether blocks comprising essentially ethylene oxide units —(C2H4—O)—, (C) being a compatibilizer chosen from (C1) low-mass copolymers of styrene and of an unsaturated carboxylic acid anhydride, (C2) copolymers of ethylene and of an unsaturated carboxylic acid anhydride, (C3) copolymers of ethylene and of an unsaturated epoxy, (C4) block copolymers (C4) SBS or SIS grafted by an unsaturated carboxylic acid or an unsaturated carboxylic acid anhydride and mixtures thereof, the weight ratio (B)/(C) being between 2 and 10.
