高分支狀聚醚醯胺及聚醚酮

Abstract

本論文討論具有大量末端官能基的高分支狀聚醚醯亞胺，藉由其末端官能基的修飾，研究其物理性質的變化。另外，透過保護聚合單體的反應官能基，如：AB2中之一個B官能基被保護，可合成出分支度為0的多官能基線形聚醚酮，再將保護基除去，可進一步合成出分支度為100 %的高分支狀聚醚酮。藉由分支度之差異，來探討高分支狀聚醚酮在不同分支度下，與其物理性質的關係。

Hyperbranched poly(ether imide)s containing a large number of chain end function groups were synthesized. The physical properties of the polymers such as thermal property and solubility were investigated and depend having on the nature of the chain end. The poly (ether ketone)s with the degree of branching ~0% and 100 % were also synthesized. The effect of the degree of branching on the physical properties of the hyperbranched poly(ether ketone)s was studied.
