Synthesis of water-soluble biologically active copolymers of acrylamide and sulfonylamidines of the (meth)acrylic series

A series of unsaturated sulfonylamidines and their copolymers with acrylamide were synthesized. The kinetics of copolymerization of acrylamide with an aminonium salt of N-methacrylamidosulfonyltrichloroacetamidine was studied in aqueous solution at 50°C. For this pair of monomers, reactivity ratios were determined. Chain transfer to sulfonylamidine group was identified as one of the causes reducing the molecular mass of the copolymers. Water-soluble copolymers of acrylamide and unsaturated sulfonylamidines were found to display antifungal activity towards pathogenic fungi and bacteria afflicting plants
