摘要
Abstract
Styrene-butadiene rubber （SBR） powder was introduced into polypropylene （PP-H） as a toughener. Mechanical properties of PP-H/SBR were studied, and the influence of a compatilizer on mechanical properties of the blend was investigated. It was found that the impact strength of PP-H/SBR/compatibilizer system was 5 times than that of neat PP-H. However, the tensile strength, stiffness, and heat distortion temperature were decreased. The compatibilizer made SBR become finer and disperse uniformly in PP-H matrix, which was considered a reason for the effective toughening.关键词
