AROMATIC POLYAMIDE WITH HALOGENO-PHENYLENE SPACER
主链含有氯代亚苯基的芳香族聚酰胺

The halogenated aromatic polyamide, which contains halogenospacer in main chain, was obtained by the reaction of 3,3-dichloro-4, 4'-diamino-diphenyl-methane and terephtha-loyl chloride. For comparison analogous nonhalogenated polymer and copolymer were prepared. The effect of chlorine substitution on the benzene ring on flammability, solubility, melting point, thermal stability, was studied by limited oxygen index (LOT), DSC, TGA and solubility measurements.
