Thermally stable polymers, method of preparation, and articles made therefrom
Multilayer articles are disclosed which comprise: a substrate layer comprising at least one thermoplastic polymer, thermoset polymer, cellulosic material, glass, or metal, and at least one coating layer thereon, said coating layer comprising at least one stabilizer additive and a thermally stable polymer comprising resorcinol arylate polyester chain members substantially free of anhydride linkages linking at least two mers of the polymer chain, prepared by an interfacial method comprising the steps of: (a) combining at least one resorcinol moiety and at least one catalyst in a mixture of water and at least one organic solvent substantially immiscible with water; and (b) adding to the mixture from (a) at least one dicarboxylic acid dichloride while maintaining the pH between 3 and 8.5 through the presence of an acid acceptor, wherein the total molar amount of acid chloride groups is stoichiometrically deficient relative to the total molar amount of phenolic groups.
