二聚酸聚氧乙烯硬脂酸酯的合成及应用初探

SYNTHESIS AND APPLICATION OF DIMERIC ACIDS POLYOXYTHYLENE STERIC ACID ESTERS

本文介绍了从二聚酸出发合成不同加成数n的二聚酸聚氧乙烯衍生物,再分别与硬脂酸进行单、双分子的接枝酯化反应。实验表明:在二聚酸非离子聚合物中引入疏水基团是可行的,制得的产物可应用于织物的柔软整理,且双酯的柔软性优于单酯。

In this paper, the dimeric acids polyoxythylene derivatives with different adduct number(n) and mono - , di - molecular esterification of these derivatives with steric acid were introduced. We found that was possible of introducing hydrophobe base in dimeric acids nonionic polymer. The products can be used ior softening finish of fibric,and softness of diester is better than monoester.
