摘　　要：本文研究了ＰＢＴ／ＰＥＴ共聚酯和共混聚合物的流变性质，分析了流变性质和结构的关系。实验结果表明，与ＰＢＴ／ＰＥＴ共混聚合物不同，ＰＢＴ／ＰＥＴ共聚酯的非牛顿指数ｎ较高，粘流活化能Ｅ值较低。组份比５０／５０的共聚酯和共混聚合物具有较低的ｎ、Ｅ值。The rheological property of PBT/PET Copolyester and PBT/PET polymer blend,and the relationship between the polymer strurture and The rheological property have been studied in this paper.It is shoon that the nen Newtonien index value (n) of PBT/PET copolyester is higler than PBT/PET blend's,but viscons flow activation energy (E) of polymer blend is smaller than copoltester's.The experimant resuit found that beth copmosition 50/50 PBT/PET copolyester and 50/50 PBT/PET polymer blend have the smallest n and E.
