It was observed that upon addition a certain amount of CuX (X = Cl/Br)/pentamethyldiethylenetriamire (PMDETA) in the presence of air
(N
Ndimethylamino)ethyl methacrylate (DMAEMA) can steadily undergo catalytic oxidative polymerization at ambient temperature.The results from gas chromatography (GC)
nuclear magnetic resonnance spectroscopy (1H-NMR) and gel-permeation chromatography (GPC) showed that both the monomer conversion and the number-average molecular weight increased gradually with the reaction time; the asprepared PDMAEMA had a structure silimar with that prepared via conventional radical polymerization.A mechanism was proposed to rationalize the above findings.
