Polyester resin material used as impact improvers and/or flow improvers, and for the production of injection moulded products, comprises polyester resin, ethylene-alpha-olefin copolymer and ethylene copolymer with epoxide groups

摘要

Polyester resin materials (I) containing: (A) 100 parts by weight (pts. wt.) polyester resin; (B) 1-50 pts. wt. ethylene/ alpha -olefin copolymer and/or ethylene/ alpha -olefin/polyene copolymer; and (C) 1-16 pts. wt. epoxide group-containing ethylene copolymer. Where the value of S = log(B) + log(C) = 2.5-4.5, where (B) and (C) are the amounts (pts. wt.) of (B) and (C) Independent claims are also included for impact strength improvers, flowability improvers and injection moulded objects consisting of (I).
