摘　　要：研究了聚对苯二甲酸乙二醇酯(PET)增强体系中,原料黏度、成核剂以及结晶促进剂对材料结晶性能的影响,并通过力学性能、热性能及DSC分析不同体系中PET的结晶性能。结果表明,特性黏数0.66 dL/g的PET原料结晶最佳,不同种类成核剂中高分子成核剂Aclyn 285是最佳成核剂,添加结晶促进剂PEG400后显著提高PET的晶体生长速度,所获PET材料结晶完善,DSC图中冷结晶峰消失。The influence of inherent viscosity,nucleation agents and crystallization promoter agent on the crystallinity of glass fiber reinforced PET materials were investigated.The crystallinity of different system was analyzed by the mechanical property,thermal property and DSC analyzing.The results indicated that PET resin with 0.66 dL/g inherent viscosity had the best crystallinity quality,Aclyn 285 was the most effective nucleating agent,the rate of crystal growth for PET was accelerated by adding crystallization promoter agent PEG400,with perfection crystal structure of PET,the cooling crystalling peak in DSC disappeared.
