| 摘 要： | 使用Ｉｎｓｔｒｏｎ３２１１型和ＢｒａｂｅｎｄｅｒＰＬＤ３３１型毛细管流交仪研究了酯型ＥＣＤＰ的流变性能。结果表明：酯型ＥＣＤＰ具有剪切变稀特性，随着第四组分含量的增加．共聚酯熔体的非牛顿指数ｎ增大，表观粘度ηａ、粘流活化能（ΔＥηａ）ｒｗ和结构粘度指数Δη下降，流动性能得到改善，对可纺性有利。

| Abstract: | Rheological properties of ester-type ECDP were studied by means of an InstronCapillary Rheometer Model 3211 and a Brabender Capill ary Rheometer Model PLD 331.The results showed that the copolyesters have the property of shear thinning;with increasingcontents of the fourth component, the non-Newton Index n of the copolyester melts willincrease, while the values of apparent viscosity ηa, flow - activation energy (ΔEηa) γw andstructural vicosity index Δη will decrease, which is beneficial to the spinnability of thecopolyesters. |
