新型含氰侧基氯取代可溶性聚芳酰胺的合成及表征

Synthesis and characterization of a new kind of chloro susbstituted soluble aromatic polyamides with pendant cyano groups

在DMAC为溶剂,叔胺为HCl吸收剂的条件下,将4,4’-二氨基二苯砜(DAPS)与自制的2,6-二(4-氯甲酰苯氧基)苯甲腈(BClPOBN)及2,5-二氯对苯二甲酰氯(DCC)进行三元低温共缩聚反应,合成一系列新型含氰侧基氯取代可溶性的聚芳酰胺。用IR、TG等方法对其结构和性能进行了表征。

A series of chloro susbstituted soluble aromatic polyamides with pendant cyano groups were synthesized by low temperature polycondensation of 4, 4＇-diaminodiphenyl sulfone with 2, 6-bis （4-chloroformylphenoxy）benzonitrile and 2,5-dichloro-1,4 benzendicarbonyl chloride in the presence of DMAC as the solvent and tertiary amines as the absorbent of HCl. LR, TG, etc. were used to characterize the polymers.
