“…Polymers containing peroxide groups in the main chain of polystyrene (PS), polyvinyl acetate (PVA) and polymethacrylic acid (PMAA) were obtained by radical polymerization in the presence of oligomeric peroxide of sebacic acid (PSA). Oligomeric peroxide was obtained by the method of interfacial polycondensation according to the method [6]. The degree of polycondensation of PSA (n) was in the range of 12-25.…”

Peroxide-containing polymers containing diacyl peroxide groups in the main chain and in the side parts of macromolecules were obtained. The thermal decomposition of peroxide groups in macromolecules is well described by the first-order kinetic equation of rate. During the decomposition of O–O groups of polymers containing peroxide groups in the main chain, a decrease in the degree of polymerization of polymers is observed. The solvent in which the process takes place and the nature of the polymer-matrix, which contains peroxide groups, affects the rate of decomposition of peroxide groups and the degree of degradation of polymer macromolecules. Peroxide-containing polymers can be successfully used to obtain block copolymers, crosslinking agents, and macromolecular initiators.

The adsorption of oligomeric peroxide of sebacic acid and benzoyl peroxide on aerosils and magnesium oxide is studied. The parameters of the adsorption processes are determined. It is shown that the adsorption occurs via formation of hydrogen bonds between surface OH-groups of adsorbents and peroxide groups. The adsorption of benzoyl peroxide on the surface of aerosils and magnesium oxide is low. The thermal decomposition of oligomeric peroxide of sebacic acid and benzoyl peroxide in the presence of aerosil is investigated. The thermal decomposition of oligomeric peroxide of sebacic acid in the presence of aerosils is faster than in a homogeneous system. The corresponding activation energy increases as the aerosil content in the system decreases. In contrast to oligomeric peroxide of sebacic acid, aerosils has no effect on the thermal decomposition rate of the benzoyl peroxide. The polymerization of styrene in the presence of aerosil leads to the formation of a mineral-polymer composite. An increase in aerosil content in the polymerization system leads to a decrease in the rate of polymerization of styrene.
