摘　　要：向聚对苯二甲酸乙二醇酯(PET)中加入一定量的聚碳酸酯(PC)及相容剂,通过双螺杆反应挤出共混造粒得到PET/PC合金,并对其热性能、力学性能等进行分析测试。结果表明:相比PET,PET/PC合金的玻璃化转变温度与冷结晶温度都得到了提升,材料的热性能得到改善。通过添加相容剂,增进PET与PC间的相容性,使得合金的韧性及加工性得到了提高。Polycarbonate and compatilizers were added into Poly(ethylene terephthalate)(PET).Through the extrusion in the twin screw,the PET/PC alloy was obtained.The results show that compared with PET,the PET/PC alloy has higher glasstransition temperature and cold crystallization temperature.So the alloy has better heat resistant.Through adding the compatilizers into the alloy,the toughness and processability have been increassed because of better compatibility.
