Abstract:
1. A curable aqueous composition comprising (a) at least one polycarboxy polymer or copolymer comprising at least two carboxylic acid groups, anhydride groups, or salts thereof; (b) at least one glycerol derivative having weight average molecular weight greater than 1000 and comprising at least three hydroxyl groups, the said glycerol derivative chosen from the group consisting of ethoxylated and propoxylated glycerol of formula I in which u, v, w, x, y, and z independently of one another are 0-50, with the proviso that the total sum of u, v, w, x, y, and z provides a weight average molecular weight of the glycerol derivative greater than 1000; wherein the glycerol derivative and the polycarboxy polymer or copolymer react with each other during heating and cure to form a flexible product, and the ratio of the number of equivalents of said carboxylic acid groups, anhydride groups, or salts thereof to the number of equivalents of said hydroxyl groups is from 1/0.001 to 1/1.
