Apparatus and method for removal of volatiles from a mass processable polymer |
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.
