ABSTRACT:
A process to produce a stable suspension of block copolymer particles in a water medium, and a stable suspension of block copolymer particles in a water medium is provided. The block copolymer is a polar functional group-containing vinyl aromatic/conjugated diolefin block copolymer which may optionally be hydrogenated. The use of C.sub.15 to C.sub.24 linear alkyl aromatic sulfonates has been found to be critical in preparation of these stable dispersions.
