FIELD: production of liquid fuel being used at low temperature. SUBSTANCE: composition comprises oil soluble ethylene copolymer. Beside fragments of ethylene derivatives said composition also comprises fragments having formula (1) <EMI ID=0.292 HE=6 WI=21 TI=CHI> and fragments having formula (2) -CH<SB>2</SB>-CRR<SP>2</SP>-, their summary amount being 7.5-35 mol %. In these formula <EMI ID=0.293 HE=3 WI=3 TI=CHI> and R<SP>2</SP>-OOCR , where R is hydrocarbyl group (wherein C is less or equal 8), proviso that fragments (1) differs from fragments (2) and if (1) is -(CH<SB>2</SB>-CH(OOCCH<SB>3</SB>),, then its content is not less than 5 mol %. Or said composition comprises oil soluble ethylene copolymer comprising 7.5-35 mol % of fragments having formula (1) and oil soluble ethylene copolymer which comprises 7.5-35 mol % of fragments having formula (2) beside ethylene derivatives. Composition may additionally comprise polymer additives. EFFECT: decreased formation of paraffin at low temperature. 25 cl, 12 tbli
