POLYKETONE COMPOSITION WITH IMPROVED IMPACT STRENGTH AND FLEXIBILITY

摘要

PURPOSE: A polyketone composition is provided to improve impact resistance and flexability and to have excellent chemical resistance, anti-fuel permeability, heat resistance, and abrasion resistance. CONSTITUTION: A polyketone composition comprises 0.01-0.5 parts by weight of an amine crosslinking agent and 100.0 parts by weight of polyketone. The polyketone is a homopolymer or alloy of a polyketone and modified rubber. The content of the modified rubber in the alloy of the polyketone and the modified rubber is 1-50%/ The modified rubber is modified by a maleic anhydride or glycidyl group. The amine crosslinking agent is diamine or triamine. [Reference numerals] (AA,CC) Polyketone; (BB) Diamine; (DD) Imine bond
