FIELD: chemistry. ^ SUBSTANCE: apparatus for producing polymer resin includes a polymerisation vessel, a support element, a protective element, a closed-cycle cooling apparatus, a starting material inlet channel and an element which defines the flow channel. The protective element forms a first flow channel between itself and the side surface of an axial mixer. The closed-cycle cooling apparatus includes a circulation inlet channel lying on the side surface of the protruding part opposite the protective element. The element which defines the flow channel lies between the support element and the protective element so as to close the side surface of the axial mixer and fix the support element and the protective element. Said element which defines the flow channel forms a second flow channel between itself and the side surface of the axial mixer, and a third flow channel for connecting the second flow channel with the starting material inlet channel. The flow channels from the first to the third make up a continuous flow channel, and the highest end of the first flow channel is open inside the protruding part. The gap, part of the first flow channel other than the highest end, the second flow channel and third flow channel are insulated from the inner zone of the protruding part. Disclosed also is a method of producing a polymer resin and a polymerisation vessel for the polymer resin. ^ EFFECT: obtaining resin of high transparency, ensuring complete and homogeneous mixing and polymerisation of the starting material, improved removal of polymerisation reaction heat. ^ 14 cl, 1 tbl, 7 dwg, 2 ex |
