DISSOLUTION OF TERT-BUTYLSTYRENE COPOLYMER INTO JET FUEL WITH THE AID OF AN HYDROXYLIC LIQUID AND AN AMINE

摘要

PV. 30779 MODIFICATION OF LIQUID HYDROCARBONS Specified copolymers of tert-butylstyrene are dissolved in a liquid aliphatic hydrocarbon fuel, especially an aircraft fuel, by the steps of (i) blending the finely-divided copolymer with a non-solvent hydroxylic liquid miscible with the fuel, (ii) mixing the blend into the fuel so as to give a copolymer concentration of 0.1 - 1% by weight, and (iii) dissolving in the fuel so treated an amino compound in an amount of 0.01 - 0.6 mole per 100g of copolymer present. The copolymers thus dissolved impart to the fuel a resistance towards mist formation when the fuel is subjected to conditions of shock.
