CO-POLYMERIZATION OF AN ISOOLEFIN WITH A HALOGENATED CO-MONOMER

摘要

A co-polymer of isobutene and 4-bromo-3-methyl-1-butene formed by direct co- polymerization in a single-step process. A continuous process for forming the co- polymer preferably comprises periodic or semi-continuous addition of catalyst to a mixed monomer solution. Semi-continuous reverse addition of the mixed monomer solution to a pre-provided catalyst solution may also be employed. The co- polymer exhibits allylic bromide functionality and is advantageously curable by either ZnO curing systems or sulfur-based curing systems.
