POLYMERISATION METHODS INVOLVING HYDROFLUOROCARBONS Russian patent published in 2009 - IPC C08F10/10 

Abstract RU 2355710 C2

FIELD: chemistry.

SUBSTANCE: invention concerns novel polymerisation methods involving hydrofluorocarbons in polymer obtainment. Polymerisation method involves contact of at least one first source material flow and at least one second source material flow in reactor system, with contact time of approximately 30 seconds or less. Method involves dilutant containing one or more hydrofluorocarbons in reactor system.

EFFECT: novel polymerisation methods and reactor system constructions reducing particle agglomeration and reactor pollution without impairing technological parametres, conditions or components and/or without impairing efficiency/throughput, and/or with possible obtainment of high-molecular polymers.
