The thermal polymerization of styrene in the presence of polymer initiators, copoly(arylene phthalides) of the diphenyl oxide series with different ratios of two adjacent (“head-to-head”) and single (“head-to-tail”) phthalide groups, was stud

The quantum-chemical simulation of possible reactions occurring at the initial stage of the free-radical polymerizations of styrene and methyl methacrylate in the presence of fullerene C60 is performed. The reactions of interaction between initiating

It has been demonstrated experimentally and theoretically that the essentially different inhibiting effects of fullerene C60 on the initial stage of the polymerizations of styrene and methyl methacrylate (including complete hampering of styrene polym

We propose a method for quantitative processing of experimental UV spectrometry data for mixtures of substituted fullerenes, taking into account measurement uncertainties. The experimental data can be represented as a system of Bouguer–Lambert line

The induction period in the kinetic curves of styrene polymerization in the presence of fullerene C60 was found to increase significantly at a solvent (benzene, toluene, ortho-dichlorobenzene, CCl4) concentration of ≥50 mol %. The free-radical poly

The antiradical activity of fullerene C60 was studied for the oxidation of 1,4-dioxane and styrene initiated by azobisisobutyronitrile and benzoyl peroxide as model reactions. The effective rate constants of the reaction of peroxyl radicals with full

Poly(methyl methacrylate) and polystyrene functionalized by fullerene C60 tend to form micellar structures comprising a fullerene cluster as a core and a macromolecular shell. Films prepared from PMMA-C60 and PS-C60 micellar solutions are polymer mat

A spectral method is developed to determine the content of fullerene in polymers formed in its presence during the free-radical polymerization and copolymerization of methyl methacrylate, allyl methacrylate, allyl chloride, and styrene. The method is

The addition of ferrocene to the styrene-benzoyl peroxide-fullerene C60 system results in changes in the kinetics of the process. This phenomenon is apparently related to not only formation of an effective redox initiating system based on benzoyl per
