Block copolymer dispersions and process to prepare block copolymer dispersions.

摘要

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 C15 to C24 linear alkyl aromatic sulfonates has been found to be critical in preparation of these stable dispersions.
