摘　　要：用溶液法制备了聚烯烃接枝马来酸酐产物(M-PE或M-PP),研究了它们与聚对苯二甲酸乙二酯的反应,探讨了偶联助剂与接枝共聚产物生成的关系,以及接枝共聚产物在聚烯烃与PET的塑料合金中的作用。结果表明,即使聚烯烃处于熔体的温度范围内,它们也对PET起促进结晶的作用。Graft copolymerization of PET on polyelefine has been studied. It is show that graft copolymer formed during the presence of coupling agent (g). The products from the reaction including coupling agent or/and blending with PET/PP, PET/LDPE has been investigated by differential scanning calorimeter (DSC) etc. The results show that coupling the PET/Polyolefine blends by g not only enhances strongly the mol. wt. of PET, but also promotes the growth rate of PET crystallization.
