ABSTRACT:
The invention is a method of making water-insoluble aliphatic primary or secondary amines, water-soluble or dispersible, which comprises reacting at a temperature of at least 120.degree. C. these amines with water-soluble acrylamide polymer which contains at least 5 mole percent acrylamide to transamidate not more than 50% mole percent of the acrylamide polymer with the water-insoluble aliphatic primary or secondary amine. The invention also covers a water-soluble or dispersible polymeric composition comprising an acrylic acid polymer having a molecular weight within the range of 500-100,000 which contains between 0.5-50 mole percent of the acrylic acid groups in the form of the amides of a water-insoluble aliphatic primary or secondary amine which contains from 10-36 carbon atoms.
