ETHYLENE/VINYL ACETATE/UNSATURATED ESTERS TERPOLYMER AS ADDITIVE ENCHANCING THE LOW-TEMPERATURE RESISTANCE OF LIQUID HYDROCARBONS |
摘要 |
Use of at least one copolymer comprising at least one alpha-olefin (78-87 mol.%), preferably ethylene; vinyl ester (12-28 mol.%), preferably at least vinyl acetate; and at least one alpha-beta unsaturated mono-carboxylic acid ester (1-4 mol.%), preferably at least 2-ethyl hexyl acrylate, as an additive for improving cold resistance and filterability of fuel, is claimed. An independent claim is included for a hydrocarbon composition comprising large quantity of medium distillate having a boiling temperature of 100-500[deg] C and minor quantity of the copolymer. |
