Synthesis of high-molecular-weight polyamine by radical polymerization of N,N-diallyl-N-methylamine

Article abstract of DOI:10.1007/BF02494771

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 ¹H NMR spectroscopy indicate that the molecules of the monomer under chosen conditions are in the protonated form. This leads to a decrease in the contribution of the reaction of degradative chain transfer to the monomer and its transformation into effective chain transfer to the monomer. A bimolecular chain termination mechanism was established and the possibility of controlling the polymerization rate and the molecular weight of the polymer was demonstrated.
