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.
