    • The present invention relates to a quick set composition and a method for preparing the composition. The composition comprises an aqueous sol of a polymer having a backbone that contains pendant cationic groups and pendant acid groups. The sol is prepared by forming a solution of a polymer that contains pendant cationic groups and pendant acid groups in an aqueous-based solvent that contains water and a suitable organic solvent and removing a sufficient amount of the organic solvent from the solution to form a composition characterized by being reversibly dissolvable and reconstitutable by addition and removal of a suitable organic solvent. The composition of the present invention provides quick-set films that can be prepared in the absence additional surface active agents and with a substantial absence of organic solvents.
    • 本发明涉及快速固化组合物及其制备方法。 组合物包含具有主链的聚合物的水性溶胶,所述主链含有阳离子侧基和侧基酸基。 通过在含有水和合适的有机溶剂的水性溶剂中形成含有阳离子侧基和侧基的基团的聚合物溶液来制备溶胶,并从溶液中除去足够量的有机溶剂以形成组合物 其特征在于通过添加和除去合适的有机溶剂是可逆地溶解和重新构成的。 本发明的组合物提供可在不存在另外的表面活性剂和基本上不存在有机溶剂的情况下制备的快速凝固膜。
