ABSTRACT:
Monoethylenically unsaturated monomers including an amide monomer are copolymerized in organic solvent solution to provide an amide copolymer solution, and volatile nitrogen-containing materials are removed from the solution without removing more than 15% of the solvent, based on the weight of the solution, and then the amide copolymer is reacted in the solution with formaldehyde in the presence of an acid catalyst, to methylolate the same.
