改性聚乙烯醇及其纺丝原液流变性能研究

A Study of the Rheologic Properties on Modifed PVA and its Spinning Solution

以聚乙烯醇为主体 ,以丙烯酰胺为改性物 ,进行迈克尔加成反应。对产物配制得纺丝原液的流变性能作了研究。结果表明 ,改性产物中含有酰胺基团的接枝率随丙烯酰胺加入量的增加而增加。

This paper deals with the analyses of modified PVA and its rheologic properties.The modified PVA was made by MICHAEL addition reaction of PVA and acrylamide,PVA was the raw material and acrylamide was additional material.The result shows that the degree of grafting of amido connects with additional amount of acrglamide.
