聚偶氮酰胺热分解性的研究

THE STUDY TO THE DECOMPOSITION OF POLYAZOAMIDE

本文研究了利用Ritter(里特)腈和碳正离子加成方法合成的新型大分子引发剂聚偶氮酰胺PPA(Ⅰ)、PPA(Ⅱ)的热分解行为。结果表明,它们是高活性、低引发效率的引发剂,不具备合成嵌段共聚物的引发剂特性。

It is studied in this paper that the thermal decomposition of polyazoamide PAA ( Ⅰ ) and PAA( Ⅱ )——a new kind of macroinitiators, synthesised according to Ritter reaction. The results indicatethat macro initiator polyazoamide with lower active energy and lower initiator eff(?)ciency, and it is not suitable for the polymerization of block copolymer.
