摘　　要：研究了在多官能团单体—三烯丙基异腈脲酸酯存在下，ＰＰ／ＬＤＰＥ共混物的辐射效应，并用ＳＥＭ、ＤＳＣ和动态力学性能对其形态结构和相容性进行了表征。结果表明：通过添加三烯丙基异腈脲酸酯，用辐射可以强化ＰＰ／ＬＤＰＥ共混物的相间结合力，改善共混物的相容性，从而提高共混物的力学性能。The radiation effect of PP/LDPE blend was investigated in the presence of polyfunctional monomer, triallyl isocyanurate (TAIC) Morpholopy structure and compatibility of the blend were characterized by SEM, DSC and dynamic mechanica l properties The results showed that the interphase adhesion was enhanced, the phase compatibility was improved and the mechanical properties of the blend was raised
