| The present invention provides a contactor apparatus and method for removing solvent from a polymer cement. The resulting polymer is substantially free of solvent and exhibits improved porosity and more uniform particle size distribution. In one embodiment, a contactor apparatus consists of a cylindrical casing having a high pressure section, a convergence section, a high velocity section, a divergence section, and a discharge section. The polymer cement is introduced into the high pressure section to significantly and unexpectedly improve solvent removal. The convergence and divergence sections preferably have cross-sectional areas that correspond to an effective angle from about 4null to about 65null. The polymer cement is mixed with high pressure steam. After converging, the polymer cement forms more uniform droplets due to high shear of steam. In the divergence and discharge sections, the polymer is substantially devolatized. | ||||||

| A process for the recovery of an initially living polymer from a cement produced in a polymerization process. The living polymer cement is shortstopped, washed, stabilised, coagulated and dried. The recovery process comprises adding a short stop to the polymer in the cement, washing catalyst residue from the polymer with water, adding an antioxidant Irganox 1520 to the cement to stabilise the polymer, adding epoxidised soya bean oil to the polymer to stabilise the polymer against colour degradation, and coagulating and drying the polymer. The pH of the cement is regulated in the range of from about 3 to about 7, and preferably from about 6 to about 7, during the catalyst wash and the coagulation steps of the recovery process. A product of the process is also described. The product and process provide for use of a preferred anti-oxidant system, which overcomes health concerns associated with existing anti-oxidant systems used in anionic polymerization processes, while providing a polymer product that has excellent colour and stability characteristics suitable for use in high impact polystyrene applications. | ||||||
