Abstract
Abstract A series of new polyesters containing the hexafluoro-2-propoxy group was synthesized by solution polycondensation. The 4-(2-hydroxyhexafluoro-2-propyl)benzoyl chloride was synthesized by dichromate oxidation of commercial available 4-(2-hydroxyhexafluoro-2-propyl)toluene and subsequent reaction with SOCl2. The homopolyester of this acid chloride as well as several copolyesters of 1,3- and 1,4-bis(2-hydroxyhexafluoro-2-propyl)benzene were synthesized. These highly crystalline polyesters show limited solubility in common organic solvents but are all soluble in dimethylacetamide-LiCl. Inherent viscosities ranged from 0.12 to 0.85 dl g−1. All of the polyesters showed similar thermal stabilities, exhibited weight loss in a single step and decomposed completely with negligible quantity of residue.
