    摘要: The present invention provides an apparatus and method of reducing volatiles in a mass processable polymer. The apparatus includes a multi-chambered devolatilizer having first and second collectors contained therein. In one embodiment, the invention provides a method that includes passing the mass processable polymer stream from a polymerization process to a first devolatilizer. The method continues by passing the polymer stream from the first devolatilizer to the multi-chambered devolatilizer. The apparatus and method allows for the production of a polymer having less than 100 ppm of volatiles.

    摘要: Provided are methods for preparing agglomeration resistant particles composed of tacky polymer compositions. The method includes the steps of providing particles of the polymer composition at or above the glass transition temperature of the polymer composition, increasing the tackiness of the polymer composition particles by contacting the polymer composition particle with a first fluid at an elevated temperature, while the polymer composition particles are in contact with the first fluid, contacting the polymer composition particles with an antiblock composition, and separating the polymer composition particles from the first fluid. These methods at least partially coat the polymer composition particles with the antiblock composition.
