INFLUENCE OF LOW-MOLECULAR-WEIGHT COPOLYMERS OF ETHYLENE WITH VINYL ACETATE ON THE LOW-TEMPERATURE PROPERTIES OF DIESEL FUEL

In the reported investigation, low mol.-wt copolymers of ethylene with vinyl acetate have been synthesized for use as pour-depressants in diesel fuels. It is demonstrated that the greatest depressant action is given by a copolymer with a mol. wt of approximately 2000, containing 30-40% vinyl acetate units by weight. This copolymer- depressant, in comparison with the other copolymers that were investigated, gives a greater depression of solid point for a diesel fuel with equal content of paraffinic hydrocarbons, and identical depression with a greater content of these hydrocarbons. The efficiency of depressant action for the copolymers in diesel fuel increases with increasing mol. wt of the paraffinic hydrocarbons present in the fuel.
