Dispersions block copolymers and process for preparing dispersions of block copolymers.

摘要

It DESCRIBED ONE TO PRODUCE A STABLE SUSPENSION OF PROCESS copolymer particles in an aqueous medium BLOCKS AND A STABLE SUSPENSION copolymer particles in an aqueous medium BLOCKS. The block copolymer is a copolymer IN BLOCKS diolefin vinylaromatic / CONJUGATE containing a polar functional group which can optionally be hydrogenated. IT HAS BEEN OBSERVED THAT USE sulfonate alkyl aromatics C 24 SUB 15 SUB LINEAR AC is critical in preparing these stable dispersions.
