Latexes are thickened by compounds of the formula ituted aliphatic, aromatic, or substituted aromatic radical having a valence of from 2 to 8; each of B1-B8 is independently an ester, amide, amine, ether, sulfide, disulfide, thiocarbamate, urea, thiourea, urethane, sulfate, phosphate, carbonyl, methylene, thioamide, carbonate, or imide linkage; each of X1-X8 is independently -A1-R2-A2- or -A1- wherein each of A1 and A2 is independently an ester, amide, amine, ether, sulfide, disulfide, urethane, thiocarbamate, urea, thiourea, sulfate, phosphate, carbonyl, methylene, thioamide, carbonate, or imide linkage and R2 is a divalent aliphatic, substituted aliphatic, aromatic, or substituted aromatic radical with the proviso that only one of B1-B8 is urethane and that when one of B1-B8 is urethane, one of A1 and A2 is not urethane; each of d, g, j, m, p, s, v, y is independently 0 or 1, each of c, f, i, l, o, r, u, x is independently any integer or non-integer from 0 to about 200; each of J, K, L, M, N, P, Q, S is 0 or 1; each of e, h, k, n, q, t, w, z is independently any integer or non-integer from 0 to about 200; each of R3-R10 is independently an aliphatic, substituted aliphatic, aromatic, or substituted aromatic radical having from 1 to about 50 carbon atoms; each of AG and AO is independently an ethyleneoxy, 1,2-propyleneoxy, 1,2-butyleneoxy unit or combinations thereof. |
