摘要
采用ＴＧＡ等手段对以聚酯二醇作为第四组份的酯型ＥＣＤＰ热稳定性进行了研究，并与以聚醚二醇作为第四组份的醚型ＥＣＤＰ进行了比较．结果表明：酯型ＥＣＤＰ具有优良的热稳定性，经１８０℃热处理３０ｍｉｎ后，酯型ＥＣＤＰ纤维强度损伤低于６％，克服了醚型ＥＣＤＰ纤维耐热性差的缺点。
The thermal stability of the ester-type ECDP, using the polyester diol as the fourth component, was studied by means of TGA method and was compared withthat of the ether-type ECDP, using the polyether diol as the fourth component. The results showed: The thermal stability of the ester-type ECDP is very well. After being treated for 30 min at 180℃, the tenacity loss of the ester-type ECDP fibres is less than 6%,but that of ether-type ECDP fibres is between 25% and 56%
