ABSTRACT OF THE DISCLOSURE Polymerization slurries of elastomeric isoolefin homopolymers and copolymers, such as butyl rubber, in dilu- ents such as methyl chloride are effectively stabilized against agglomeration of polymer particles through addi- tion of minor proportions of an hydrogenated preformed copolymer stabilizer having both a lyophobic and a lyo- philic portion. The chemical and structural nature of the lyophobic and lyophilic portions which comprise the co- polymer stabilizer are significant in determining the ex- tent and method of hydrogenation for production of the most effective stabilizer. Agglomeration of polymer prod- ucts is effectively prevented, yielding a number of signi- ficant processing advantages. The process is especially adaptable to the production of isobutylene-isoprene butyl rubber.
