The cyclized carbonate of an amino aromatic acid, such as isatoic anhydride, or an acrylic acid halide, such as acryloyl chloride have been found useful in functionalizing hydroxy terminated polycarbonates.

Method of functionalizing hydroxy terminated polycarbonate with isatoic

Low odor polyphenylene ether/polystyrene resins are produced in a process by solution blending low odor polyphenylene ether and polystyrene resins and passing the solution through devolatilizers prior to recovery.

Low odor polyphenylene ether/polystyrene process

Carboxy-functionalized polycarbonates are prepared by incorporating a carboxylic acid-substituted phenol, preferably t-butyl p-hydroxybenzoate, as a chainstopper in a polycarbonate-forming reaction. The products are capable of forming copolymers with other polymers such as polyamides and functionalized olefin polymers, by generation of a carboxy group which reacts therewith.

Heating polyphenylene ether in the presence of isotoic anhydride and organic solvent has been found to enhance the thermal stability of the polyphenylene ether.

Thermoplastic materials may be functionalized and then blended with polyamides to form compatible products which contain a copolymer of the functionalized material and the polyamide.

Functionalized thermoplastic polymers, blends prepared therefrom, and

A method for preparing thermoplastic carbonate polymers terminated with hydroxy groups is disclosed, in which a dihydric phenol is reacted with a carbonyl halide in the presence of a monotetrahydropyranyl ether salt. The hydroxy-terminated polymer is then obtained by cleaving the tetrahydropyranyl group with oxalic acid or a hydrogen halide acid.
