Acid hydrolysis, under relatively mild conditions (3N HCI, 100°C), of a series of homopolymers of N-vinyl-N-methylacetamide, and copolymers thereof with vinyl acetate or methyl acrylate, afforded poly(N-vinyl-N-methylamine), poly(N-vinyl-N-methylamine-co-vinyl alcohol) and poly(N-vinyl-N-methylamine-co-acrylic acid) in almost quantitative yield. A simple and practical route to poly(N-vinyl-N-methylacetamide-co-acrylic acid) and poly(N-vinyl-N-methylacetamide-co--vinyl alcohol) has been developed and some kinetic results relating to the hydrolysis step are given. The products were characterized by viscometry, elemental analysis and NMR spectroscopy.

Water-soluble polyacrylamides have often been used to modify flow response in various water-based technologies and industrial processes, including paints, water treatment, paper manufacturing, and chemical enhanced oil recovery. Polymers are...
