Patent ID: 6914091

Claim:
An emulsion or dispersion comprising: I′) a dispersed polymer phase comprising at least one hydrogenated block copolymer which comprises at least two distinct blocks of hydrogenated vinyl aromatic polymer, and at least one block of hydrogenated conjugated diene polymer, wherein the hydrogenated copolymer is further characterized by: a) a weight ratio of hydrogenated conjugated diene polymer block to hydrogenated vinyl aromatic polymer block of greater than 40:60; b) a total number average molecular weight (Mn t ) of from 30,000 to 150,000, wherein each hydrogenated vinyl aromatic polymer block (A) has a Mn a of from 5,000 to 45,000 and each hydrogenated conjugated diene polymer block (B) has a Mn b of from 12,000 to 110,000; and c) a hydrogenation level such that each hydrogenated vinyl aromatic polymer block has a hydrogenation level of greater than 90 percent and each hydrogenated conjugated diene polymer block has a hydrogenation level of greater than 95 percent, II′) a surfactant, and III′) a continuous phase which is immiscible with the polymer phase.
