TOUGHENED POLYKETONE COMPOSITION

摘要

A polymer composition comprising: (A) a major amount of a polyketone having a linear alternating structure of (a) units derived from carbon monoxide and (b) units derived from one or more olefinically unsaturated compounds; and (B) a minor amount of an amine functionalised elastomer wherein the amount of amine incorporated in the elastomer is from about 0.01 to 2.0 % by weight of the total weight of component (B). By carefully selecting the amount of amine which is incorporated in the elastomer the impact strength of the polyketone is improved.
