【摘要】 本文研究了高温下ＥＤＤＰ和ＰＥＴ的特性粘度和端羧基含量的变化，比较了ＥＤＤＰ和ＰＥＴ的热稳定性，结果表明，由于改性剂的引入使ＥＤＤＰ的热稳定性较ＰＥＴ有所下降更多还原

【Abstract】 In this paper,the change of intrinsic viscosity and acid end group of Easy Dispersed Dyeability Polyester(EDDP) and PET at high temperature are studied comparing thermostebility of EDDP with PET.The results show that thermostability of EDDP is lower than PET,because modified agent is added in micromolocular.更多还原
