ABSTRACT:
The invention concerns thermoplastic polyesters (such as PET or PBT) comprising, by weight, the total being 100%: 60 to 99% of thermoplastic polyester; 1 to 40% of impact modifier comprising: (a) a core-shell copolymer (A), (b) an ethylene copolymer (B) selected among ethylene copolymers (B1) and an unsaturated carboxylic acid anhydride, ethylene copolymers (B2) and an unsaturated epoxy compound and mixtures thereof, (c) a copolymer (C) selected among ethylene copolymers (C1) and an alkyl (meth)acrylate, ethylene copolymers (C2) and (meth)acrylic acid optionally neutralised and mixtures thereof. The invention also concerns an impact modifying composition which can be added in thermoplastic polyesters to improve their shock-proof properties and comprising constituents (A), (B) and (C).
