摘　　要：环氧乙烷环氧丙烷无规聚醚 ( EPO)是高速纺丝油剂的重要组分。引发体系中的微量水分影响EPO相对分子质量和起始端基结构 ,进一步影响其使用性能。通过研究真空蒸馏方式、三元共沸反应精馏方式、二元共沸反应精馏方式对不同沸点醇类无规聚醚引发体系水分含量的影响 ,提出了适用于以醇类物质为起始剂的 EPO的起始端基结构控制方法。The random copolymer of ethylene oxide and propylene oxide(EPO) is an important component of high\|speed\|spinning finish. Trace water in the initiator system is a crucial factor which affects the head\|end structure and the performance of EPO for high\|speed\|spinning finish. The influence of process conditions of vacuum distillation, ternary azeotropic rectification, binary azeotropic rectification on water content of the initiator systems of atactic polyether with different boiling point was studied. The control method of the head\|end structure of EPO is put forward.
