Polymers are described having repeat units of Formula (I): wherein R3 is H or alkyl group; x and t are positive integers; Q is C(O)O, C(O)NH, or direct bond; D is alkylene, arylene, or (CH2CH2O)n(CH(CH3)CH2O)m; E is O, S, NR5, or direct bond; R5 is H or alkyl; G is the residue of a polyisocyanate; V is a urethane, urea, or thiourea that bonds to other parts of the polymer compound or to a monovalent blocking group; s is 1 to 5; Y is O or a substituted or unsubstituted arylene group; A is an alkylene group; w, v, and y are 0 or 1; X is the residue of a cyclic or acyclic sugar alcohol which is substituted with —R1, —C(O)R1, —(CH2CH2O)n(CH(CH3)CH2O)mR2, —(CH2CH2O)n(CH(CH3)CH2O)mC(O)R1, or mixtures thereof; n and m are independently 0 to 20; R1 is independently an alkyl group; and R2 is independently —H or alkyl group.
