Abstract:<\/p>\n

Kinetic studies have shown that the use of systems based on secondary and tertiary hydroperoxides with N, N-diethyldithiocarbamate copper (II) can be used as effective sources of free radicals in the polymerization of methyl methacrylate in moderately low temperatures region (323\u2013343 K). The introduction of an aromatic ring in molecules of hydroperoxides (ethylbenzene hydroperoxide and cumene hydroperoxide) increases the reactivity of the initiating system \u00abhydroperoxide \u2013 complex\u00bb in comparison with tertiary butyl hydroperoxide. The shift of the gel effect to the region of high conversions during the polymerization of methyl methacrylate was noted. Such systems allow not only to accelerate the polymerization of the monomer, but also to conduct it in a controlled mode. H1 NMR spectroscopy showed that the formed polymers contained end dithiocarbamate fragments. Such groups are labile. It has been shown that the obtained and isolated in the presence of the initiating system tertiary hydroperoxide \u2013 N,N-diethyldithiocarbamate of copper(II) polymers are macroinitiators that can initiate a new portion of the monomer.<\/p>\n
