摘要
Abstract
Polypropylene(PP) has excellent mechanical property,processing property, chemical resistance and so on. However,the poor impact toughness of PP,especially high fragility under low temperature conditions,limits further applications of PP in some areas where high impact toughness is required. The paper summarizes the current research status of toughening modification methods of PP from the aspects of chemical modification and physical modification, and emphasizes the current toughening modification method of PP by inducing PP to form β-crystal form. In addition,opinions and suggestions for solving problems of PP toughening modification are put forward.关键词
