  • Method of separating a polymer from a solvent
    Patent number: 7226989
    Abstract: 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.

  • Preparation of by the bischloroformate process of soft segment polycarbonate
    Patent number: 5494997
    Abstract: 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.
