“…Polyperoxides are unique in the sense that this class of polymers degrade highly exothermically in contrast to common polymers which usually degrades endothermically . Since polyperoxides exhibit unusual phenomenon of auto‐pyrolysis, they are potential candidates as an auto‐combustible fuel . Moreover, this class of polymers have great utility in the field of coating, dismentable adhesion, synthesis of branched polymer, as thermal and photo‐initiator for vinyl monomers to prepare homopolymers and block copolymers, and so on.…”

Water soluble alternating copolymers were prepared by oxidative free radical copolymerization of 4‐vinylbenzyl methoxypoly(oxyethylene) ether (PEGSt) and molecular oxygen at 50 °C. NMR spectroscopy established alternate sequence of PEGSt and peroxy bonds (OO) along the polymer main‐chain. The obtained polymers show temperature induced hydrophilic to hydrophobic phase separation, confirmed by UV‐visible spectroscopy and dynamic light scattering. The cloud point temperature (TCP) of the polymers can be tuned by changing the chain length of side‐chain poly(ethylene oxide) and incorporation of hydrophobic methyl methacrylate in the copolyperoxides. Exothermic degradation of these polyperoxides was confirmed by differential scanning calorimetry and the degradation products have been characterized by electron impact mass spectroscopy. Finally, N,N‐dimethylacrylamide was polymerized in the presence of these polyperoxides in toluene, highlighting their potential as polymeric free radical initiator during polymerization of vinyl monomers. © 2018 Wiley Periodicals, Inc.

“…Compared to conventional peroxides, the polyperoxides have been shown to produce comb-like polymers [5] and interpenetrating networks. [6] Vinyl polyperoxides, [1 -4] which are alternating copolymers of oxygen and vinyl monomers, are of current interest not only due to their wide range of applications but also possess special features such as high exothermic degradation, [7,8] and exhibit the unusual phenomenon of auto-pyrolysis and auto-combustion [9] (explaining their role in the paradoxical effect of oxygen in vinyl polymerization), [10,11] their use in developing novel fuels [12] and curatives in coating and molding applications. [13] These apart, the vinyl polyperoxides are superior to acid poly-peroxides [14,15] as they are less sensitive to heat, shock, or friction and have better solubility in all vinyl monomers.…”

The stable vinyl polyperoxide, namely, poly(α‐phenylstyrene peroxide) (PAPSP), an alternating copolymer of α‐phenylstyrene and oxygen, has been synthesized by the oxidative polymerization of α‐phenylstyrene. It was characterized by 1H and 13C NMR, FT‐IR, DSC, GC‐MS and GPC studies. The overall activation energy (Ed) for the degradation of PAPSP was found to be 45.0 kcal/mol. The stability of PAPSP was estimated from its isothermal degradation rate and compared with other related vinyl polyperoxides. Thermal initiating potentialities of PAPSP have been studied by polymerizing styrene at 80°C. The polymerization follows classical kinetics. The mechanism of polymerization has been discussed. The active polymer, which contains PAPSP segments in the polystyrene chain was confirmed by 1H NMR study. The values of K2 for PAPSP compared to that of 2,5‐dimethyl‐2,5‐dihydroperoxyhexane and di‐tert‐butyl peroxide at 80°C indicate that PAPSP can be used as an effective high temperature initiator.

“…Vinyl polyperoxides are of interest due to their potential applications. [21,22] Studies on graft or block copolymerization of polymeric peroxides, such as poly(amethylstyrene peroxide), poly(styrene peroxide), and poly(methyl methacrylate peroxide)s with monomers have been carried out.…”
