PLANT AND METHOD OF PRODUCING FLOW-MIXED POLYMER Russian patent published in 2024 - IPC B01J19/18 B01J19/24 C08F2/01 C08F2/04 C08F210/16 

FIELD: processing of plastics.

SUBSTANCE: group of inventions can be used in the manufacture of polymer materials. Plant for producing a flow-mixed polymer comprises first reactor line for production of first polymer, second reactor line for production of second reactor and mixing unit for mixing of first and second polymers. First reactor line includes the first polymerisation reactor and the first purification separator located after the reactor. Second reactor line includes the second reactor and the second purification separator located after the reactor. First and second separators are connected to the mixing unit located after the separators. Ratio of internal volumes of the first and second reactors is in range from 95:5 to 55:45. Invention also discloses a version of the plant and a method of producing a flow-mixed polymer.

EFFECT: group of inventions increases melting and glass transition temperatures of the polymer while maintaining its density and melt flow rate.
