METHOD OF SYNTHESIS OF THE THICKENING ADDITION AGENT FOR MOTOR OIL

摘要

FIELD: chemical technology. SUBSTANCE: method involves cationic polymerization of vinylbutyl ester in the presence of catalyst - aluminiumsesquiethyl chloride at its mass ratio to monomer = (0.3-0.5):100. Process is carried out in the medium of solvent - hydrocarbon of C, C-fraction at 20-50 C. Preferably to use solvent that contains additionally mineral oil at its mass ratio to hydrocarbon = (5:95)-(99:1). EFFECT: improved method of synthesis.
