A thermoplastic molding composition comprising an aromatic carbonate polymer and a polyester derived from a cyclohexanedimethanol.

Thermoplastic molding composition

A composition comprising (a) an aromatic polycarbonate and (b) a minor amount of a oxyalkylene siloxane block copolymer, and, optionally, an organic phosphite or phosphonite and/or epoxy compound provide lower viscosity in the melt without producing brittle molded parts.

Composition comprising an aromatic polycarbonate and a

A thermal oxidative stabilized polycarbonate composition comprises in admixture (a) a high molecular weight aromatic carbonate polymer and (b) a minor amount of an end-blocked polyorganohydrogen siloxane and, optionally, an organic phosphite or phosphonite and/or epoxy compound.

Stabilized polycarbonate compositions

Novel thermoplastic molding compositions are disclosed which comprise a polycarbonate and a halocarbon oil, wax or grease.

Polycarbonate compositions

A stabilized and plasticized polycarbonate composition comprising in admixture, an aromatic carbonate polymer and a stabilizing amount of an essentially monomeric organic silane. The composition can additionally contain a phosphite and/or an epoxy compound.

Organic silane stabilized and plasticized polycarbonate composition

A thermoplastic composition of a combination of polyesters comprising a poly(1,4-butylene terephthalate) and a polyester derived from a cyclohexanedimethanol.

A thermoplastic molding composition comprising a polycarbonate, a poly(1,4-butylene terephthalate) and a copolyester of an aliphatic or cycloaliphatic diol and a mixture of terephthalic and isophthalic acids.

A plasticized polycarbonate composition comprising in admixture a high molecular weight aromatic carbonate polymer and a minor amount of an ester.

Polycarbonate composition plasticized with esters

A process for preparing a thermoplastic randomly branched aromatic polycarbonate which process comprises reacting at least 20 weight percent of a stoichiometric quantity of a carbonate precursor with a mixture of a dihydric phenol and at least 0.05 mole percent of a polyfunctional aromatic compound in a medium of water and a solvent for the polycarbonate having present therein at least 1.2 mole percent of a polymerization catalyst, while concomitantly adding to the reaction medium sufficient alkali metal hydroxide to maintain a pH range of about 3.0 to about 6.0, and then adding sufficient alkali metal hydroxide to raise the pH to at least about 9.0 to less than about 12 while reacting the remaining carbonate precursor.
