This article considers the use of a pour-point depressant consisting of a mixture of ethylene with methyl methacrylate (EMMA) and ethylene with vinyl acetate (EVA) to improve the low-temperature indexes of diesel fuels. It is determined that the greatest effect with respect to limiting filterability temperature from the addition of EMMA is achieved with an EVA content of approximately 0.04%. The use of both a copolymer promoting the formation of a large number of crystallization centers (EMMA) and a copolymer that is a good modifier of the wax crystal surface (EVA) leads to a limitation of the crystal growth and preservation of the fine-crystal structure as the fuel temperature is lowered.
