摘要: 热塑聚酞胺树脂是由植物油聚合脂肪酸与乙二胺制得的分子量3000~9000的线型缩聚物.早期的树脂溶于芳烃用作柔性印刷油墨的粘合剂.这种树脂芳烃溶液气味大,污染环境、危害工人健康.Glaser等用多乙撑多胺和轻基酸进行聚酞胺树脂化学改性,制得了醇溶性聚酞胺树脂,但溶液的低温稳定性差.可添加轻基酸和(或)经基多胺参与共聚制备醇溶性树脂.本文系统研究了经基丙二胺和蓖麻醇酸改性剂及其用量对改性聚酞胺树脂的醇溶性、软化点以及树脂溶液的稳定性的影响.

Abstract: The alcohol-soluble polyamide resins have been obtained by copolymerization of amixture comprising polymeric fatty acid,ricinoleic acid and sebacic acid with ethylenediamineand 1,3-diamino-2-hydroxypropane. In an appropriate proportion of ricinoleic acid to 1,3-di-amino-2-hydroxypropane the polymerized product exhibits an improved low temperature solubility in lower molecular aliphatic alcohols and higher softening point.
