ABSTRACT

Blending polypropylene (PP) into acrylonitrile-butadiene-styrene (ABS) resin to improve its solvent resistance and reduce the water absorption rate. Then, polypropylene-graft-polystyrene (PP-g-PS) was prepared by using pre-irradiation and suspension-grafting technique to improve the compatibility of ABS/PP blends. The FTIR result demonstrated that PS was grafted onto PP successfully, and SEM showed that the interface of ABS/PP was improved owing to the existence of PP-g-PS. The solvent resistance and mechanical properties of ABS/PP were improved and water absorption rate was reduced after blending PP-g-PS.

通过与PP共混并使用PP-g-PS作为增容剂来改善ABS的性能

摘要

将聚丙烯（PP）与丙烯腈-丁二烯-苯乙烯（ABS）树脂共混以提高其耐溶剂性并降低吸水率。然后，通过预辐照和悬浮接枝技术制备聚丙烯接枝聚苯乙烯（PP- g -PS），以提高ABS / PP共混物的相容性。FTIR结果表明，PS成功地接枝到了PP上，SEM表明由于PP- g -PS的存在，ABS / PP的界面得到了改善。共混PP- g -PS后，ABS / PP的耐溶剂性和机械性能得到改善，吸水率降低。
