the new approach to the preparation of polyacrylamide-based

the new initiator of the polymerization of acrylamide, leading to the formation of crosslinked polyacrylamide, was discovered. the structure of the synthesized polyacrylamide was characterized by xrd, 1h nmr, and 13c nmr spectroscopy. it was shown that 1,3-dimethylimidazolium (phosphonooxy-)oligosulphanide is able to initiate radical polymerization under drying aqueous solutions of acrylamide
