THE FRACTURE TOUGHNESS OF POLYPHENYLENE SULFIDE TOUGHENED WITH HIGH PERFORMANCE THERMOPLASTICS
高性能热塑性树脂增韧聚苯硫醚的韧性

The fracture toughness(G_(ic))and fracture morphology of polyphenylene suifide(PPS)toughened with high performance thermoplastic bisphenol A polysulfone(PSF),polyetherketone with cardo group(PEK-C)have been studied.Both systems showed the im-proved impact strength and fracture toughness of PPS.The toughened effect has been affectedby the method of blend.
