“…In-depth characterization of the thermal decomposition of organic peroxides, from the chemical and kinetic point of view, is thus useful both for industrial applications and safety considerations. Dicumyl peroxide (DCP) is one of the most widely used peroxides in the polymer industry as a cross-linking agent for polyethylene and with ethylene vinyl acetate copolymers, and it has been used as a curing agent for unsaturated polystyrene . It has been reported that its thermal decomposition, due to temperature control failure and/or process disturbances, is likely to lead to the occurrence of runaway phenomena. , Although many reports have focused on the effect of acid catalysts upon DCP thermal stability, it is amply recognized that, even in the absence of such catalysts, this peroxide undergoes thermal decomposition when heated in solutions of cumene .…”

A kinetic model is developed to simulate the thermal decomposition of dicumyl peroxide (DCP) in cumene with\ud and without oxygen in the reacting system, based on a reaction network that is comprised of a set of 51 reactions. An optimization\ud procedure is adopted to obtain the best estimates for most of the related kinetic parameters, few of which are available in\ud the literature. The model is successfully validated by simulating the concentration profiles of all the species participating in\ud the decomposition of DCP in cumene, under varying initial conditions, using previously best-estimated values of the kinetic\ud parameter

“…In the rst step, organic peroxide undergoes homolytic cleavage at high temperature to form peroxide-free radicals. e primary radicals can be fragmented into secondary radicals [6,13,14]. Peroxide radical species then react with rubber chains leading to the formation of macromolecular radicals, which usually recombine to form carbon-carbon cross-links [13,[15][16][17].…”

Rubber magnetic composites were prepared by incorporation of barium ferrite in constant amount—50 phr into acrylonitrile-butadiene rubber. Dicumyl peroxide as the curing agent was used for cross-linking of rubber magnets alone, or in combination with four different types of co-agents. The main aim was to examine the influence of curing system composition on magnetic and physical-mechanical properties of composites. The cross-link density and the structure of the formed cross-links were investigated too. The results demonstrated that the type and amount of the co-agent had significant influence on cross-link density, which was reflected in typical change of physical-mechanical properties. The tensile strength increased with increasing amount of co-agents, which can be attributed to the improvement of adhesion and compatibility on the interphase filler-rubber due to the presence of co-agents. Magnetic characteristics were found not to be influenced by the curing system composition. The application of peroxide curing systems consisting of organic peroxide and co-agents leads to the preparation of rubber magnets with not only good magnetic properties but also with improved physical-mechanical properties, which could broaden the sphere of their application uses.
