Dicarbonyl Chlorides and Dicarboxylic Acids
Dicarbonyl chloride and dicarboxylic acids are functional groups that co-react with bis(2-aminophenol) in the synthesis of polybenzoxazole (PBO) polymers. They provide the carbonyl groups required to form the benzoxazole ring in the PBO polymer. These compounds were chosen because of their ability to withstand high temperatures and maintain mechanical integrity under extreme conditions. PBO polymers synthesized from dicarbonyl chloride and dicarboxylic acids have found applications in high temperature composites and protective coatings. Examples of dicarbonyl chloride and dicarboxylic acids used in PBO synthesis include terephthaloyl chloride and isophthalic acid.
