摘要
不同品种聚乙烯共混物的晶相相容性与聚乙烯的支化度有非常密切的关系,同时与共混物的热历史也有一定的关系。不同品种聚乙烯的红外差谱和其共混物的差动热分析表明,共混物两组分的支化度越接近,晶相相容性越好,反之,相容性越差。扫描电镜分析表明,不同热历史可改变共混物结晶的规整性。
The compatibilily of crystalline phases of different polyethylene blendsrelated to the branching degree of polyethylene very closely,and also in cer-tain extent related to the heat history of the blends.IR differential spectr-um of different polyethylene and DSC of their blends showed that the closerthe branching degree of the two blended components the better the compatibi-lity of crystalline phases,and vice Versa.SEM showed that different heathistory can change the crylstall regularily of blend crystals
