摘要: 以聚对苯二甲酸乙二酯(PET)瓶片为主要原料, 加入聚碳酸酯(PC)、热塑性弹性体及扩链剂, 采用低温固相反应挤出制备了具有良好强度与韧性的新型合金. 在加工过程中产生PET相和PC相互穿的网络结构的同时, 反应性扩链剂在PET相中发生交联反应, 形成了次级网络结构. 由于这些网络结构的存在, 使合金材料的力学性能得到明显提高, 特别是缺口冲击性能有了明显的改善.

Abstract: By adding of chain extender and thermo plastic elastomer, PET/PC reactive alloys were prepared via low temperature solid-state blending. Novel toughening alloy is gained with outstanding mechanical properties and thermal properties. The structures of PET/PC alloys were studied and the multiple network which was formed by this processing greatly reinforced the alloy.

Key words: PET/PC alloy, Low temperature solid-state processing, Reactive blend, Multi-network, Reinforced structure
