摘要： A process for preparing a copolyestercarbonate which comprises reacting interfacially a dihydric phenol, a carbonate precursor, and a saturated aliphatic alpha omega dicarboxylic acid having from 9 to about 40 carbon atoms wherein the said diacid is from about 2 to about 20 mole percent based on the dihydric phenol reactant content and wherein the initial pH is from about 8 to about 9 for about 70 to about 95% of the carbonate precursor addition time period time period and is then raised to a final pH of from about 10 to 12 for the remainder of the carbonate precursor addition time period.

摘要： A process for preparing a polyestercarbonate copolymer which is nearly devoid of diaryl-carbonates and that exhibits a glass transition temperature lower than bisphenol-A carbonate homopolymer, and that shows improved processability is herein described. The desired lower Tg and improved flow can be achieved by the polycondensation of a dihydric phenol and aliphatic dicarboxylic acid. The condensate is polymerized with a carbonate forming reagent.

摘要： A method of separating a polymer-solvent mixture is described wherein a polymer-solvent mixture is heated prior to its introduction into an extruder comprising an upstream vent and/or a side feeder vent to allow flash evaporation of the solvent, and downstream vents for removal of remaining solvent. The one-step method is highly efficient having very high throughput rates while at the same time providing a polymer product containing low levels of residual solvent.
