On the Functions of Molecular Sponge in Heterophase Chain Reactions of Block Polymers (on the Example of Polystyrene Arylation by Dibenzoyl Peroxide)

Abstract

Features of interactions of amoqhous polystyrene with dibenzoyl peroxide, which are not explained by the homogeneous mechanism, are described by the heterophase scheme possessing two conjugated reactionary paths, localized in separate shuctural zones of polymer matrix. The reaction scheme is based on the carcass-micellar model of supermolecular organization. according to which zones of two types exist in molecular-sponge cells. These zones, different by fluctuation dynamics of polymer chains and sizes of micropores (traps for reacting particles) provide inadequate condition for excitation of the acts of initiation, propagation and termination of the reaction sequences. The principle of the interzone conjugation of kinetic chains under the conditions of fluctuation dynamics of the molecular sponge chains, limited by the supermolecular carcass, is exhibited.

A Three-Step Synthesis of Benzoyl Peroxide

“…Chemically, it is used as a polymerization initiator for the synthesis of polystyrene and acrylate polymers and copolymers. 6 These polymers are crucial components to Super Glue, plexiglass, and many types of plastics. Benzoyl peroxide's bleaching properties make it a common additive in many foods, including flour, cheese, and whey.…”

“…Benzoyl peroxide also has applicability in industrial, food science, and dental applications. Chemically, it is used as a polymerization initiator for the synthesis of polystyrene and acrylate polymers and copolymers . These polymers are crucial components to Super Glue, plexiglass, and many types of plastics.…”
