PROBLEM TO BE SOLVED: To obtain the subject composition capable of developing excellent weld strength, toughness, mold release properties and low anisotropy, electricity and electron-related instruments, by mixing a crystal resin with a specific polyketone copolymer in a prescribed ratio. SOLUTION: This composition comprises (A) 50-99.99 wt.% of a crystal resin [e.g. a crystal polyester (amide) containing an ethylene dioxide unit as an essential component and having 900-60,000 weight-average molecular weight] and (B) 0.01-50 wt.% of a polyketone copolymer composed of a repeating unit (B1 ) of formula I and a repeating unit (B2 ) of formula II in the molar ratio of the component B2 /B1 of 0.01-0.10. Preferably, the composition contains further (C) 0.001-10 wt.% of a compound which is a metal phosphate or a metal (hypophosphite) phosphite based on 100 pts.wt. of the component A besides the components A and B. |
