Latexes are thickened by compounds of the formula (I): R<1>-(O-A)a-B<1>-R<2>-(B<2>-R<3>)d-(B<3>-(A'-O)b-f-(A'-B<4>)f-R<4>-(B<5>-R<5>)e)n-B<6>-(A''O)c-R<6>, wherein: R<1> and R<6> are monovalent hydrophobic groups independently selected from the group consisting of an aliphatic group, a substituted aliphatic group, an aromatic group, and a substituted aromatic group; R<2> and R<4> are independently selected from the group consisting of aliphatic, substituted aliphatic, aromatic, or substituted aromatic radicals, each radical being divalent or trivalent; R<3> and R<5> are independently selected from hydrogen, lower alkyl and lower aralkyl; B<1>, B<2>, B<3>, B<4>, B<5>, and B<6> are linking groups independently selected from the group consisting of an oxygen atom, carboxylate group, an amino group and an amido group, each of a, b, c, d, e, f, and n are integers, wherein each of a and c are independently any integer from greater than 20 to about 200; b is any integer from greater than 20 to about 450; d, e, and f are 0 or 1; and n is any integer from 1 to about 5; and each of A, A', and A'' is independently an ethylene, 1,2-propylene, 1,2-butylene unit or combinations thereof.
