摘要： A thermoplastic composition is disclosed, containing poly(arylene ether) resin; vinyl aromatic resin; a hindered amine light stabilizer; an ultraviolet light absorbing compound, and about 0.1 % by weight to about 2.0 % by weight of titanium dioxide, based on the total weight of poly(arylene ether) resin and vinyl aromatic resin. Other thermoplastic compositions described herein contain poly(arylene ether) resin; vinyl aromatic resin; an ultraviolet light absorbing compound, and at least one methine yellow colorant. Molded articles prepared from these compositions are also described.

摘要： Block copolyestercarbonates may be prepared by first conducting a reaction between at least one of resorcinol or an alkyl- or haloresorcinol and at least one aromatic dicarboxylic acid dichloride, preferably isophthaloyl dichloride, terephthaloyl dichloride or a mixture thereof, to produce a hydroxy-terminated polyester intermediate, and then conducting a reaction of the intermediate with a carbonate precursor, preferably in the presence of a dihydroxy compound such as bisphenol A. The products have excellent physical properties, including a high degree of weatherability. They may be blended with other polymers such as polycarbonates, poly(alkylene carboxylates), polyarylates, polyetherimides, and addition polymers to improve the weatherability thereof.
