摘要
Abstract
Four kinds of impact copolymer polypropylene were researched by dynamic mechanical analysis instrument on the mode of dual cantilever.The DMA curves revealed the presence of two Tg peaks in all samples,indicating the amorphous phase of ethylene-propylene rubbers and polypropylene (PP).According to the basic physical properties,the ethylene and ethylene-propylene rubber content and the investigation of the SEM phase structures,it can be found that sample 1 # behaved the better Izod impact strength and toughness at both high and low temperature for the better compatibility between the ethylene-propylene rubbers and PP.DMA also can be used to evaluate the impact of microstructure on the physical properties quickly and visually.关键词
