ABSTRACT:
The present invention relates to a free radical emulsion polymerization process for the formation of substantially gel-free terpolymers of a major portion of a mixture of butadiene and styrene and a minor portion of a sulfonate containing monomer wherein the terpolymers are water insoluble and have about 18 to about 100 meq. of sulfonate groups per 100 grams of polymer.
