用DSC和X 射线衍射法研究了茂金属线形低密度聚乙烯 (m PE LLD)与高密度聚乙烯 (PE HD)、低密度聚乙烯 (PE LD)、线形低密度聚乙烯 (PE LLD)共混时PE HD、PE LD、PE LLD不同加入量对m PE LLD非等温结晶行为和结晶动力学的影响。研究结...用DSC和X 射线衍射法研究了茂金属线形低密度聚乙烯 (m PE LLD)与高密度聚乙烯 (PE HD)、低密度聚乙烯 (PE LD)、线形低密度聚乙烯 (PE LLD)共混时PE HD、PE LD、PE LLD不同加入量对m PE LLD非等温结晶行为和结晶动力学的影响。研究结果表明 :PE HD与m PE LLD共混使样品结晶峰变窄 ,结晶度和结晶速率有所提高 ,说明两者有较好的相容性与共结晶行为 ;PE LD的加入使共混物结晶峰变宽 ,说明PE LD与m PE LLD共结晶行为较差 ,存在部分相分离 ,但在PE LD含为 2 0 %时有最大结晶度 ,结晶速率有所提高 ;PE LLD的加入对m PE LLD非等温结晶和动力学影响较小。X展开更多
