摘　　要：设计并合成了一系列含有磺酸盐基团化合物和不同聚乙二醇(PEG)添加量的新型共聚醚酯(COPEET),研究了它们的常规性能、玻璃化转变温度、结晶温度、熔融温度及热失重等性能随PEG添加量的变化,又将COPEET与低密度聚乙烯(LDPE)以60/40的质量比进行共混熔融纺丝,可纺性好,并得到了以COPEET为分散相的基体-微纤型纤维,经剥离后得到线密度低于0.001 dtex的超细纤维,可用于制成超纤合成革。A series of COPEET with different amount of PEG and containing sulfonate group was synthesized.The normal property,glass transition temperature,crystallization temperature,milt temperature and thermal degradation behavior of COPEET were studied when PEG adding increased.The blend melt spinning of COPEET/LDPE was carried out,and it showed good spinnability when the mass ratio of COPEET/LDPE was 60/40.The SEM photo of the blend fibers' vertical section showed to be two-phase structure.Finally,microfiber of 0.001 dtex was obtained.
