“…the conversion equivalent, is not referred to the conversion of specific species present in the compound, although it is a lumped representation of various crosslinks formed or dissociated during the crosslinking of elastomers. The power law model was initially applied for crosslinking of polyethylene (PE) [9] and then for several other polymers [10], nitrile butadiene rubber (NBR) [11], fluorinated elastomers [12], ethylene-propylene-diene monomer rubber (EPDM) [13][14][15][16][17], EPDM/PE blends [18], poly(ethylene-co-methyl acrylate)/ poly(dimethyl siloxane) (PDMS) blends [19], PE/PDMS blends [20], poly(ethylene-co-vinyl acetate) (EVA)/PDMS blends [21], and epoxidized polybutadiene (BR) [22]. The model developed by Piloyan, on the other hand, was applied for processing of PE [23] and crosslinking of PE foams [24].…”

The chemistry of peroxide crosslinking was considered with the intention of the development of a fundamental kinetic model for the crosslinking process. The kinetics of the crosslinking of several elastomers by action of organic peroxides was studied, where dicumyl peroxide (DCP), t‐butyl peroxide (TBP), and di(2‐t‐butylperoxyisopropyl) benzene (DTBPIB) have been chosen as representative peroxides. The reaction mechanisms that have been proposed for the different steps in crosslinking chemistry were critically evaluated with the objective of developing a general description of the governing chemistry, where the mechanisms are consistent for all reaction steps in the crosslinking process. A fundamental kinetic model has been developed for the peroxide crosslinking, using population balance method that explicitly acknowledges the nature of the elastomer backbone and network, and thus reactants, intermediates and products with various reactivities. The kinetic model simulation was able to describe the complete crosslinking process including homolytic cleavage of the peroxide, beta cleavage of the oxy radical, hydrogen abstraction, addition reactions, radical coupling (crosslink formation), polymer scission and radical transfer for a wide range of compositions, and assortment of elastomers, using a single set of rate constants.

“…The title compound, (I), a simple organic peroxide, has gradually become almost the most important additive in operations affected by molecular transport, such as grafting (Konar et al, 1993;Ramar & Alagar, 2004) and cross-linking (Wang et al, 1998;Ferrero, 2006), which are based on the formation of oxyradicals due to the thermal decomposition of the peroxides. It's widely used in the art as vulcanizing agents for resins and elastomers, as cross-linking agents for polyolefins.…”
