Abstract: A method of preparing a poly(ester-carbonate) includes contacting an aqueous solution including a dicarboxylic acid with a first solution including phosgene and a first organic solvent in a tubular reactor to provide a first reaction mixture. A dihydroxy aromatic compound, the corresponding dialkali metal salt of the dihydroxy aromatic compound, or a combination comprising at least one of the foregoing, water, and a second organic solvent are combined to provide a second reaction mixture. The method further includes introducing the first reaction mixture, the second reaction mixture, and a second solution comprising phosgene to a tank reactor, wherein the tank reactor has a first pH of 7 to 10. The pH is optionally raised to 9 to 11 to provide a third reaction mixture including the poly(ester-carbonate). Poly(ester-carbonate)s prepared according to the method described herein are also disclosed.

Abstract: A process for the manufacture of polycarbonate particles is disclosed herein. The process includes combining a first solution including a polycarbonate and a phosphorus-containing flame retardant or a flame retardant polycarbonate, and an organic solvent with a second solution including a surfactant and an aqueous solvent substantially immiscible with the organic solvent, under conditions of shear and temperature effective to provide an emulsion. At least a portion of the organic solvent is removed from the emulsion to provide an aqueous slurry having a plurality of particles, wherein the particles include the polycarbonate and the phosphorus-containing flame retardant or the flame retardant polycarbonate.

Abstract: A process for the manufacture of thermoplastic polymer particles include combining a first solution having a polyetherimide, a polycarbonate, or a combination thereof and an organic solvent with an aqueous solution including a surfactant, and agitating the resulting mixture using a shear force generating device operating at a preselected peripheral rotational speed to provide an emulsion. The emulsion is heated to remove the organic solvent and provide an aqueous polymer dispersion including the thermoplastic polymer particles.

Abstract: An interfacial process for preparing a poly(aliphatic ester-carbonate) includes providing an initial polymerization reaction mixture comprising an aliphatic C6-20 dicarboxylic acid, a bisphenol, an alkali hydroxide, and optionally a catalyst in a solvent system comprising water and an immiscible organic solvent, adding an initial portion of a carbonyl dihalide over a first time period while maintaining the reaction at a first pH from 7 to 8; and adding a second portion of the carbonyl dihalide over a second, subsequent time period while maintaining the reaction pH at a second pH from 9 to 12, to provide a product polymerization mixture, wherein the amount of alkali hydroxide in the initial polymerization reaction mixture is effective to increase the fraction of the first time period at a measured pH of 7 to 8 compared to the same reaction mixture with a higher amount of alkali hydroxide in the initial polymerization mixture.
