FIELD: chemistry.
SUBSTANCE: invention relates to low-molecular ternary copolymers of vinylidene fluoride and a monomer containing a fluorosulphate group of general formula: 
, where Rf=-CF2OSO2F, -CF2O(CF2)2OSO2F; l=29-66; m=9-18; n=2.4-4 with number-average molecular weight 3000-9000.
EFFECT: obtaining low-molecular ternary copolymers of vinylidene fluoride, having high fluidity, on the basis of which, in the absence of a solvent, cold curing oil-and-petrol resistant sealants can be obtained, having good physical and mechanical properties and having high stability during contact with aggressive media.
