METHOD OF PRODUCING POLYMERS Russian patent published in 2017 - IPC C08F2/01 C08F20/56 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing polymers. Described is a method of producing a polymer product. An aqueous mixture containing monoethylenically unsaturated monomer or a mixture of monoethylenically unsaturated monomers is fed into a first reactor device. First reactor device comprises a positive displacement pump. Monomer or mixture of monomers is partially polymerised. Polymerised monomer or mixture of monomers is transferred from inlet to outlet of first reactor to produce partially polymerised product. At moment of outflow from first reactor in partially polymerised product not than 60 % of monomer or mixture of monomers is polymerised. Polymerisation is continued in next reactor device. Polymer product is removed from output of next reactor.

EFFECT: technical result is providing a method for more continuous production of polymer with low content of residual unreacted monomer.
