More particularly, the dispersant so treated will usually comprise a mono or bis-oxazoline prepared by reaction of a hydrocarbyl-substituted C.sub.4 -C.sub.10 dicarboxylic acid or anhydride or ester thereof, having at least 50 carbon atoms in the hydrocarbyl group, with a 2,2-disubstituted 2-amino-1-alkanol that has from two to three hydroxy groups and that contains from 4 to 8 total carbon atoms.

Abstract: Polymerization slurries of elastomeric isoolefin homopolymers and copolymers, such as butyl rubber, in diluents such as methyl chloride, are effectively stabilized against agglomeration of polymer particles through addition of minor proportions of (i) a preformed copolymer stabilizer having both a lyophobic or lyophilic portion, or (ii) an in situ formed stabilizer from a functional lyophilic stabilizer precursor capable of copolymerizing or otherwise chemically bonding with the polymer product. Agglomeration of polymer products is effectively prevented, yielding a number of significant processing advantages. The process is especially adaptable to the production of isobutylene-isoprene butyl rubber.
