研制了一种大分子主链上含有金属盐的聚醚酯型抗静电剂PEEM，将少量PEEM与PET切片共混纺丝可制备抗静电PET纤维，其抗静电性能优良、耐久，且优于不含金属盐的聚醚酯型抗静电纤维。本文用红外、ITA、萃取等方法研究了抗静电剂和抗静电纤维的结构、性能。“,”Ihe antistatic agent (PEEM) contained metallic salt is studied.The antistatic PET fiber is Prepared by acding small amount ofPEEM in PET during blend spinning process. It is shown that the antistatic property of this PET fiber is better than that of without metallicsalt. The properties and stucture of antistatic fiber and PEEM are studied by IR, DTA and extracting etc.
