Oxidative Polymerisation of Vinyl Monomers

Synthesis, spectral characterization, and thermochemical studies of poly(phenyl methacrylate peroxide)

“…in addition to copolymers with oxygen. 1 The features of the simultaneous occurrence of polymerization and oxidation have been the subject of numerous investigations, and it has led to the establishment of oxidative polymerization as an independent field of radical-chain polymerization.…”

First report on a semicrystalline vinyl polyperoxide

“…In fact, no crystallinity in polyperoxides is known, although more than a dozen of them have been reported so far. [1][2][3][4][5][6][7][8] In an effort to obtain a crystalline polyperoxide that has a simple and experimentally realizable structure, we found poly(␣-phenyl styrene peroxide) (PAPSP) to be a suitable candidate. It has the required symmetry and sufficient flexibility, although tacticity and intermolecular forces are absent just as in polyethylene.…”

Determination of the Reactivity Ratios for the Oxidative Copolymerizations of Indene with Methyl, Ethyl and Butyl Acrylates

“…Polymerization of vinyl monomers in the presence of high pressures of oxygen, called oxidative polymerization yields alternating copolymers with oxygen, known as polyperoxides. [1,2] They find importance as polymeric fuels, [3] thermal, [4,5] photo [6] and base catalyzed initiators [7] for vinyl monomers to synthesize homopolymers, block copolymers and novel comb polymers and curators in coating and moulding applications. [8] Polyperoxides have gained considerable interest over the past several years because of their unique highly exothermic pyrolysis behavior, [9] in contrast to other common polymers which generally degrade endothermically.…”

“…The term oxidative copolymerization [2,11] is applied when two monomers (R 1 and R 2 ) reacting in the presence of oxygen at high pressures, produce copolymers of the type 1 [(R 1 1O1O1 ) X 1 (R 2 1O1O1 ) Y 1 ] n . Compared to simple vinyl polyperoxides obtained from a vinyl monomer and oxygen, those obtained by the copolymerization of a mixture of vinyl monomers in the presence of oxygen have been less studied.…”

“…Compared to simple vinyl polyperoxides obtained from a vinyl monomer and oxygen, those obtained by the copolymerization of a mixture of vinyl monomers in the presence of oxygen have been less studied. [2] In an earlier work on the oxidative copolymerization, relative rates of oxidation of different monomers and their reactivity towards a peroxide radical was investigated. [12,13] The oxidation of two monomers can be considered as a special case of terpolymerization, when the monomers do not homopolymerize.…”
