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