Almraet--Aqueous thermal polymerization of acrylonitrile (AN) initiated by peroxomonosulphate (HSO~, PMS)-thioglycolic acid (TGA) redox system was studied in the temperature range 30-60 Β°. The effects of [monomer], [initiator], [reducing agent], pH, ionic strength and temperature on rate of polymeri

The kinetics of aqueous polymerization of acrylonitrile initiated by peroxomonosulphate-Co(II) redox system have been investigated in the range 30-50Β°C under nitrogen at a fixed ionic strength of 0.30mol-dm -3. The overall rate of polymerization, followed gravimetrically, was found to be proportiona
Kinetics of the polymerization of acrylonitrile initiated by an acidic peroxo salt (potassium monopersulphate) catalysed by Mn(II) have been investigated in aqueous systems over the range 30-50'. The rates of polymerization (Rv) have been studied for various concentrations of monomer and initiator.
The mechanism of initiation of e-caprolactone polymerization by stable salts has been investigated. Gel permeation chromatography and ~H-NMR spectroscopy were used for determining the compositions of the reaction mixtures and of the polymers. It was established that the initiation proceeds by additi
