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.
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
