Claim:
1. A composition comprising linked segments of: (a) a polyhydroxy segment derived from a compound independently selected from the group consisting of an acyclic polyhydric alcohol having 4 to 6 carbon atoms and 4 to 6 reactive hydroxyl groups; a cyclic polyhydric alcohol having 4 to 6 carbon atoms and 4 to 6 reactive hydroxyl groups, a poly(hydroxyethyl) polyethyleneamine having 4 to 6 reactive hydroxyl groups and combinations thereof; (b) polyoxyalkylene segments wherein each hydroxyl group of the polyhydroxyl segment is linked to a polyoxyalkylene segment, wherein each polyoxyalkylene segment has a weight average molecular weight ranging 3,000 g/mole to 10,000 g/mole; (c) and aliphatic end segments or aromatic end segments, each end segment having 6 to 32 carbon atoms and a hydroxyl reactive group, wherein the hydroxyl reactive is an epoxide group, 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.
