COMPOSITIONS USEFUL AS COATINGS, THEIR PREPARATION, AND ARTICLES MADE THEREFROM

摘要

A composition comprising components A, B and optionally C, wherein component A comprises at least one carboxy-terminated polyarylate or an otherwise functionalized polyarylate. Component B is an organic species which can react with the reactive endgroups of component A, and component C is a catalyst or mixture of catalysts. The carboxy-terminated and functionalized polyarylates may be prepared by a solution polymerization method wherein a stoichiometric excess of a diacid chloride is reacted with a dihydroxy-substituted aromatic compound (e.g. resorcinol) in the presence of an organic base to provide an intermediate chlorocarbonyl group-substituted polyarylate which chlorocarbonyl groups may be elaborated to a variety of reactive endgroups including carboxy groups and epoxy groups.
