Abstract The first synthesis of high-molecular-weight poly (N, N-diallyl-N-methylamine) by thermal (at 30 and 50° C) and photoinduced (at 21° C) radical polymerization of N, N-diallyl- N-methylamine (DAMA) in aqueous solution in the presence of an equimolar amount of trifluoroacetic acid (TFA) and by polymerization of the newly synthesized equimolar DAMA· TFA salt is reported. Data of 1 H NMR spectroscopy indicate that the molecules of the ...
