PP/LDPE共混体系的辐射效应

Radiation Effect of PP/LDPE Blend System

摘要: 研究了在多官能团单体—三烯丙基异氰脲酸酯存在下ＰＰ／ＬＤＰＥ共混体系接受γ－辐射的效果。用溶解度参数和ＴＥＭ技术评估了共混体系的相容性与多官能团单体在共混体系中的分布，并用ＳＥＭ、ＤＳＣ、动态力学等方法对共混体系相容性进行了表征。结果表明，ＰＰ／ＬＤＰＥ是不相容的共混体系，三烯丙基异氰脲酸酯主要分布在共混体系的相界面区域，辐照强化了共混体系的相间结合，增加了界面厚度，改善了共混体系的相容性。

Abstract: The radiation effect on PP/LDPE blend is investigated in the presence of trifunctional monomer, triallyl isocyanurated (TAIC).According to the solubility parameters of the monomer and polymers and TEM, the distribution of TAIC in PP/LDPE blend is estimate
