摘要
制备了以聚对苯二甲酸乙二醇酯(PET)为基体的复配型PET结晶成核剂母料——Nu-1;利用DSC研究了不同添加量的Nu-1对PET结晶行为的影响;对比了该成核剂与科莱恩公司的101和杜邦公司的Surlyn对PET结晶行为的影响。结果表明:Nu-1的加入可以有效促进PET结晶的成核速率,随着添加量从2%升高到5%,PET的结晶速率明显提高。在添加量相同时,Nu-1对PET结晶的促进作用接近101和Surlyn。
A new kind of nucleation agent (Nu-1) for PET was prepared, whose effect on the crystallization behavior of PET was studied and compared with 101 and Surlyn. It showed that in the Nu-1 based system the rate and degree of crystallization were near to the other two.
