Abstract:
An ICI viscosity regulating composition including linked segments of: (a) a polyhydroxy segment having 4 to 6 reactive hydroxyl groups; derived from a compound selected from: an acyclic or cyclic polyhydric alcohol having 4 to 6 carbon atoms, an alkoxylated acyclic polyhydric alcohol, an alkoxylated cyclic polyhydric alcohol and a poly(hydroxyethyl)polyethyleneamine; and combinations thereof; (b) aliphatic or aromatic linking segments, each linking segment having at least two linking groups independently selected from the group of: urethane, urea, ether, ester, amine, an aminoplast segment, a linking group which is the residue from reaction of an epihalohydrin and a hydroxyl group, and mixtures thereof; (c) polyoxyalkylene segments; (d) and aliphatic or aromatic end segments, each end segment having 6 to 22 carbon atoms and a linking group reactive moiety, wherein the mole ratio of the polyoxyalkylene segment to the polyhydroxy segment is at least 4:1 and the mole ratio of the aliphatic or aromatic end segment to the polyhydroxy segment is at least 0.25:1.
