COMPOSITION OF POLYKETONE WITH HIGH IMPACT STRENGTH

摘要

PURPOSE: A polyketone composition is provided to maintain durability, chemical resistance, fuel permeability, etc while maintaining performance of polyketone and to remarkably improve impact resistance. CONSTITUTION: A polyketone composition comprises 40-90 weight% of polyketone, 5-40 weight5 of polyamide, and 5-20 weight% of modified rubber. The flow index of the polyketone is 5-70 g/10min, the flow index of the polyamide is 5-70 g/10min and the flow index of the modified rubber is 0.5-30 g/10 min. The polyamide is one or more kinds selected from polyamide 6, polyamide 66, polyamide 6/66 copolymer, polyamide 610, polyamide 612, polyamide 11 and polyamide 12.
