| Abstract: | The radical copolymerization of N,N-diallyl-N,N-dimethylammonium chloride (AMAC) (M1) with ethylene glycol vinyl ether (M2) in an aqueous medium proceeds at a high rate to afford random copolymers. The reactivity ratios equal to r 1 = 2.18 and r 2 = 0.01 indicate that AMAC is a more active comonomer. The overall reaction order in comonomers is 2.4, and the effective activation energy is 97.4 ± 2 kJ/mol. The monomer M1 enters into copolymerization by both of the double bonds with the formation of pyrrolidinium structures in the chain through the cyclization stage. |
