摘要： NEW WATER-SOLUBLE TO WATER-DISPERSIBLE REACTION PRODUCTS ARE PROVIDED WHICH ARE OBTAINED BY CONDENSING A CARBOXYLIC ACID POLYMER WITH AN ALKYLENIMINE AND AN ALKYLENE OXIDE. A TYPICAL PRODUCT OF THE PRESENT INVENTION IS OBTAINED BY CONDENSING A POLYACRYLIC ACID WITH ETHYLENIMINE AND PROPYLENE OXIDE. THE NOVEL CONDENSATION PRODUCTS OF THE PRESENT INVENTION HAVE A PLURALITY OF UTILITIES. THE CONDENSATION PRODDUCTS OF THIS INVENTION EXHIBIT PROPERTIES WHICH MAKE THEM EPECIALLY USEFUL IN PAPER-MAKING APPLICATIONS, AS DRAINAGE AIDS, FLOTATION AIDS, FLOCCULATING AIDS, RETENTION AIDS, AND AS WET STRENGHT RESINS.
