FIELD: chemical industry; methods of production of polyethylene in the tubular reactors with curing chambers or without them.
SUBSTANCE: the invention is pertaining to the method of production of polyethylene in the tubular reactors with the curing chambers or without them. The method provides, that the chain-radical initiator with cold ethylene or without it is fed into the flowing liquid medium containing ethylene with a comonomer. Conduct swirling of two being mixed streams at an angle or by means of the provided swirling component - in the cross section of the stream. In the zone of the area of introduction of the chain-radical initiator there is a narrowing of the cross-section, in which through a eccentrically located optimized outlet hole of the finger-shaped feeding component in the swirled stream introduce the chain-radical initiator.
EFFECT: the invention ensures a reliable introduction of the initiator in the tubular reactors with curing chambers or without them.
