FIELD: chemistry.
SUBSTANCE: invention relates to compositions of an aqueous emulsion of organic peroxide. Disclosed is a composition of an aqueous emulsion of organic peroxide for the polymerisation or copolymerisation of unsaturated monomers of the ethylene series, containing (wt%): one or more organic peroxides (10–65); at least one anti-gelling agent (2–25); at least one emulsifier (0.01–10); optionally at least one additive; water, the amount of which is determined so as to make up the remainder of the total weight of the composition (up to 100); wherein the emulsifier is a colloidal agent, which is polyvinyl acetate with a degree of hydrolysis greater than 80 %, and a viscosity determined for an aqueous solution with a concentration of 4 wt% at 20 °C less than or equal to 3 mPa⋅s, wherein the viscosity is determined by a Brookfield RVT viscometer, spindle No. 3, 20 rpm, according to ISO 2555. Invention also relates to a method for producing said composition and to its use.
EFFECT: use in the claimed composition of said emulsifier allows to achieve the stability of the emulsion without increasing the viscosity of the emulsion in the cold, which leads to unsatisfactory expiration time.
