Abstract

We have synthesized four kinds of polyhydroxyamides (PHAs) via low-temperature solution polymerization of 2,2-bis(3-amino-4-hydoxyphenyl)hexafluoropropane or 3,3'-dihydroxybenzidine with isophthaloyl chloride or terephthaloyl chloride in N,N-dimethylacetamide and 1-methyl-2-pyrrolidone, respectively. The chemical structures of the synthesized PHAs and the polybenzoxazoles(PBOs) obtained by heat-treatment of the PHAs were identified using FT-IR spectroscopic analysis. We studied the thermal cyclization behavior of the PHAs and related this behavior to their chemical structures. DSC and TGA results showed that both the thermal cyclization temperatures and the thermal stabilities were decreased by introduction of fluorine into the main chain of the PHAs.
