Abstract:
Multilayer articles comprising a coating layer comprising resorcinol arylate chain members bound to a support substrate via an optional intermediate tie layer. Adhesion between the layers of the multilayer article is enhanced by modifying at least a part of a surface of at least one of the layers in the multilayer article by a technique selected from at least one of: surface adhesive treatment, surface corona treatment, flame treatment, plasma surface treatment, vacuum deposition treatment, ionization radiation, chemical surface treatment, surface abrasion treatment, and surface texturing treating.
Abstract:
A coating composition comprising components A, B and optionally C, wherein component A comprises at least one hydroxy-terminated polyarylate. Component B is an organic species which can react with the hydroxy terminal groups of component A, and component C is a catalyst or mixture of catalysts. The hydroxy-terminated polyarylates are prepared by a solution polymerization method.
Abstract:
A method of preparing block copolyestercarbonates wherein al one dihydroxy-substituted aromatic hydrocarbon moiety and at least one aromatic diacid chloride are reacted under interfacial conditions to give a hydroxy-terminated polyester intermediate. The dihydroxy-substituted aromatic compound is used in about 10 mole to about 125 mole percent excess relative to the diacid chloride. Enhanced control of hydroxy-terminated polyester intermediate molecular weight is achieved by limiting the amount of water present to provide a final salt level of greater than 30 percent. The final salt level is a theoretical value but is readily calculable. The hydroxy-terminated polyester intermediate is then converted to a block copolyestercarbonate by reaction with a carbonate precursor such as phosgene.
Abstract:
Compositions made from a polyarylate or polyester carbonate containing greater than about 50 mole % resorcinol based ester linkages give miscible blends with polyimide resins. The blends of polyimides and resorcinol based polyesters or resorcinol based polyester carbonates also give miscible blends when combined with other aryl alky polyester resins.

Abstract:
The present invention relates to a polymer composition comprising a transparent polymer blend. The polymer blend comprises a first resin and a second resin. The first resin comprises polyarylate structural units of formula I, wherein R1 is independently at each occurrence a C1-C12 alkyl group, or a halogen atom, and p is 0 to 3. The second resin is selected from the group consisting of polycarbonates, polyarylates and copolyestercarbonates. The first resin and the second resin are further characterized by a difference in polyarylate structural unit conte
