Abstract

Abstract:

The fatigue⁃resistance performance of PC/ABS alloys under a high temperature of 90 ºC were investigated in the terms of acrylonitrile⁃butadiene⁃styrene terpolymer （ABS） phase， polycarbonate （PC） phase， and compatilizers. The results indicated that the rubber phase in the alloy was the main factor that weakens the fatigue resistance. It was beneficial to improve the property by increasing the mass ratio of styrene⁃acrylonitrile binary copolymer to polybutadiene in the alloy. Meanwhile， increasing the proportion of PC or reducing the viscosity of PC was capable of strengthening the fatigue⁃resistant property. There was an influence on the fatigue resistance from the addition of different types of compatilizer， in which polypropylene⁃grafted⁃maleic Anhydride （PP⁃g⁃MAH） exhibited optimal performance.

Key words: polycarbonate, acrylonitrile?butadiene?styrene terpolymer, alloy, high temperature fatigue resistance, compatilizer, automobile
