聚酯(高分子)特性粘数在30℃的一点法测定研究
摘要
本工作用粘度法
在30℃测定聚酯的赫金斯(Huggins)常数以及特性粘数
并与25℃测得的特性粘数比较
结果这两种温度下测出的特性粘数值很为接近
偏差小于0.009
故聚酯在25℃的特性粘数
可以用30℃的测定结果来表示.
Abstract
In this paper
the measuring method of Huggins constant and intrinsic viscosity of polyester at 30℃ is introduced. The results have been compared with the intrinsic viscosity at 25℃ and the error is less than 0. 009
