Abstract
The present invention relates to a free radical emulsion polymerization process for the formation of substantially gel-free co- or terpolymers of a major portion of at least one conjugated diene and a minor portion of a sulfonate containing monomer, wherein the co- or terpolymers are water insoluble and have about 18 to about 100 meq of sulfonate groups per 100 grams of polymer.
