POLYMERISATION IN AQUEOUS EMULSION WITHOUT EMULSIFIERS TO OBTAIN COPOLYMERS OF FLUORATED OLEFIN AND HYDROCARBON OLEFIN Russian patent published in 2008 - IPC C08F214/18 C08F210/02 C08F210/06 C08F2/22 C08F14/18 

FIELD: chemistry.

SUBSTANCE: described is the method of synthesising copolymers from fluorated olefin and hydrocarbon olefin, selected from ethane, propylene and mixtures of these substances, containing in essence water-emulsion polymerisation, not containing emulsifiers, fluorated olefin and hydrocarbon olefin, then copolymerisation of fluorated olefin and hydrocarbon olefin in the presence of fluoropolymer particles and/or in the presence of fluorinated liquid with a boiling point of at least 50°C at atmospheric pressure in a form, meant for improving the process of copolymerisation of fluorated olefin and hydrocarbon olefin, in this case fluoropolymer particles are formed In Situ due to polymerisation of parts of fluoropolymer olefin without substantial copolymerisation of hydrocarbon olefin or assuming that fluoropolymer particles are added at the beginning of polymerisation, and polymerisation is thermally initiated in case polymerisation is carried out in the presence of fluoropolymer particles, at that water-emulsion polymerisation, in essence free of emulsifier, means that a fluorinated surface-active substance is not available or its content is less than 500 ppm in relation to the amount of water in the system of polymerisation during its addition to the water-phase.

EFFECT: creating an effective mode of synthesizing copolymers from fluorated olefin and hydrocarbon olefin.
