Abstract
Bioresorbable or biodegradable polymers formed from the monomers including sulphonyl diphenol, hydroxybenzoic acid and dicarboxylic acid. The dicarboxylic acid can include aliphatic dicarboxylic acid or a mixture of aliphatic dicarboxylic acid and aromatic dicarboxylic acid. Between 25 and 85 molar percent of the polymer is formed from the hydroxybenzoic acid, between 7.5 and 37.5 molar percent of the polymer is formed from the sulphonyl diphenol, and between 7.5 and 37.5 molar percent of the polymer is formed from the dicarboxylic acid. Polymers can be used for manufacturing fibers and composite devices.
