. Based on the copolymerization products of styrene, low molecular weight polyethylene and large-scale petrochemical waste - bottoms distillation of butyl alcohols, a bifunctional additive for diesel fuels with depressant and lubricating properties has been developed. The maximum filterability temperature of diesel fuels with the developed additive was up to minus 32 ° C, the adjusted diameter of the wear spot was 438 mm.
styrene, low molecular weight polyethylene, butanol distillation residues, depressor and lubricating properties.
