    摘要: 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.

    摘要: Novel reverse osmosis membranes and a method for preparing such membranes are described. A substrate can be coated with a first compound bearing a plurality of onium groups and a second compound bearing a plurality of nucleophilic groups. The resulting coating cures readily upon exposure to actinic radiation.

    摘要: Heat exchange fluids are improved by incorporating therein a viscoelastic surfactant composition. The viscoelastic surfactant is employed in an amount sufficient to reduce the friction experienced by the heat transfer fluid in a heat transfer apparatus while providing good heat transfer. The improved fluids are useful in district heating applications.
