METHOD OF PRODUCING LOW-MOLECULAR COPOLYMERS OF TETRAFLUOROETHYLENE AND PROPYLENE Russian patent published in 2018 - IPC C08F214/26 C08F16/24 C08F2/06 

Abstract RU 2674034 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method for producing low molecular weight copolymers of tetrafluoroethylene and propylene and can be used in the industry of synthetic rubber for thermo-aggressive resistant sealants, protective coatings and composites that are resistant to long-term operation at elevated temperatures. Method for producing low molecular weight copolymers of tetrafluoroethylene and propylene by copolymerizing monomers of tetrafluoroethylene and propylene in the presence of a solvent and an initiator is described. Initiator is tert-butylperoxy-benzoate or tert-butylperoxy-2-ethylhexyl carbonate or compounds of the general formula C2F5(CF2OCF(CF3))n-C(O)OOC(O)-(CF(CF3)OCF2)nC2F5 where n=0–2.

EFFECT: method allows to obtain low molecular weight copolymers of tetrafluoroethylene and propylene with an increased yield in combination with a simplified technology.
