FIELD: chemistry.
SUBSTANCE: proposed is a polymerisation method for producing (co)polymer of one or more monomers from which at least 50 wt % is vinyl chloride, an in which one or several organic peroxides, chosen from a group consisting of diacyl peroxides, peroxy esters, peroxydicarbonates and their mixtures, are used together with control agents, chosen from a group consisting of organic hydroperoxides, organic compounds with ethylene saturation, which cannot be homo-polymerised, compounds with unstable carbon-hydrogen bonds, oximes and their mixture, under the condition that, solubility of peroxydicarbonate (peroxydicarbonates) in water at 0°C is not less than 5 pts/mln. The method is a standard polymerisation method in an aqueous dispersion or a polymerisation method in an aqueous dispersion in which at least part of one or several organic peroxides, used as the initiator, is added to the reaction mixture at polymerisation temperature. The invention also relates to formulations, containing organic peroxide and sufficient amount of additive, stabilising the organic peroxide, suitable for use in the given polymerisation method and (co)polymers, obtained using method of polymerisation in an aqueous dispersion.
EFFECT: wider field of using the compounds.
