Abstract

PP was toughened by polyolefin elastomer(POE), and the mechanical properties, thermal properties, work of fracture and micromorphology of PP/ POE blends were studiedThe uniform distribution of POE in PP matrix and fine combination between PP and POE were seen from the results With the increase of POE content the number of elastomer particles increased but the diameter unchanged Both the impact and fracture toughness of the blends were improved with the introduction of POE The softening point of the blends decreased appreciably , which showed little effect on the processing properties
