聚苯胺在一些有机溶剂中溶解性

本文通过改变反应条件用化学方法制得了不同分子量的聚苯胺，考察了它们在有机溶剂中的溶解性．实验结果表明：分子量的大小是影响它们在有机溶剂中溶解度的主要因素，能在有机溶剂中溶解的只是聚苯胺中分子量较小的级分．我们还用聚苯胺（［η］＝０．４９ｄｌ／ｇ）与－ＣＯＣＩ封端的果对苯二甲酰对苯二胺（ＰＰＴＡ）进行嵌段共聚，经过产物的元素分析与计算结果比较，确定出特性黏数为０．４９ｄｌ／ｇ的聚苯胺平均分子量．

SOLUBILITY OF POLYANILINE IN SOME ORGANIC SOLVENTS

olyaniline (PANI) with various inherent viscosities have been synthesize under a number of different reaction conditions. Their solubilities in organic solventshave been studied. It was found that the best solvent for PANt isN-methylpyrrolidone (NMP ) and only low molucular weight PANt can be dissolved in organic solvents. Soluble PANt ([η] =0. 49dl/g) in NMP was used tocopolymerize with -COCI terminated low molecular weight poly- to - phenylene terephathalamide). Through elemental analysis the molecular wdght of PANt hasbeen ascertained.
