Abstract
A process for halogenating polymers by contacting a polymer either in solution or in bulk with a halogenating agent in the presence of an acid scavenger. Halogenated polymer, e.g., butyl rubber, with a particular structure is obtained and the product suffers less molecular weight loss. Combinations of acid scavengers can also be used and the scavenger can be dispersed in the polymer prior to halogenation and/or added to the reaction zone during halogenation.
