Title:
PROCESS FOR POLYMERIZING CATIONICALLY POLYMERIZABLE MONOMERS
Document Type and Number:
WIPO Patent Application WO2004014968
Kind Code:
A3
Abstract:
The invention relates to a new catalyst system that improves the heat transfer capability of a butyl reactor slurry process system in the production of isobutylene-based polymers in continuous slurry polymerization processes. The process is carried out in an anhydrous polymerization system containing a mixture of the monomers in a polar diluent along with a Lewis acid and a CS or greater initiator having a tertiary halide.
