摘要

提出了利用多个宽分布聚合物试样的［η］和ＧＰＣ谱图在计算机上运用五点搜索法寻找［η］的最小偏差的程序来解得聚合物的Ｍａｒｋ-Ｈｏｕｗｉｎｋ方程参数的新方法．并应用此法确定了聚环硫氯丙烷在四氢呋喃溶液中３０℃下的Ｍａｒｋ-Ｈｏｕｗｉｎｋ方程参数为：α＝０.７７１

Ｋ＝０.５９２×１０－４．经［η］的误差分析及ＶＰＯ证实

得到的Ｋ、α值是可靠的

用于计算［η］及分子量时

相对误差均在６％之内．

Abstract

A new rapid method for the determination of Mark Houwink equation constants from GPC and intrinsic viscocity data on a number of samples ( n >5) with a five point hunting program was described. The Mark Houwink equation constants of poly (Chloromethy thiirane) in THF solution at 30℃

which are 0 771 ( α ) and 0.592×10-4 ( K )

were obtained by this method. The obtained K and α values were reliable and could be used for calculating the molecular weights of poly (chloromethyl thiirane) within the relative error of 6%

which was proved by [η]error checking and VPO analysis.
