Abstract
A viscosity regulating composition and its method of manufacture. The composition comprises a mixture of (a) a branched polymer having the formula [M]-[(A1O)-L1-(A1O)—R1]n, wherein M is polybranched hydrophobe; A1O is a polyoxyalkylene unit; L1 is an aliphatic linking segment or an aromatic linking segment each having at least two hydroxyl reactive linking groups; and R1 is an aliphatic end unit or aromatic end unit having 6 to 32 carbon atoms; n ranges from 3 to 6; and (b) a polymer having the formula R2-(A2O)-L2-(A2O)—R2, wherein (A2O) is a polyoxyalkylene unit, L2 is a aliphatic linking segment or an aromatic linking segment, and R2 is a aliphatic unit or an aromatic unit each having 6 to 32 carbon atoms.
