【摘要】 研究了相容剂ＬＤＰＦｇＡＳ对ＨＤＰＥ／ＡＳ共混体系形态及力学性能的影响。红外光谱研究表明采用固相接枝有效地形成了苯乙烯和丙烯腈与聚乙烯的接枝共聚物，将其作为ＨＤＰＥ／ＡＳ共混体系的相容剂可大大减小分散相的粒子尺寸，显著提高共混体系的力学性能，说明ＬＤＰＥｇＡＳ是该共混体系的有效相容剂更多还原

【Abstract】 s The effet of LDPEgAS on the morphologies and mechanical properties of HDPE/AS blend system was studied.The results of IR spectrum showed styrene and acrylonitrile were grafted onto PP by means of solid graft reaction,and the use of LDPEgAS as compatibilizer for the blend could reduce the dispersed phase size and bring about obvious improvement in the mechanical properties of the blend,which showed LDPEgAS was an effective compatibilizer for the blend system.更多还原
