More Information
Summary:FIELD: lubricants. SUBSTANCE: isobutylene/alpha- methylstyrene copolymer containing between o.1 and 300 wt % alpha-methylstyrene and having molecular weight from 500 to 3000 is brought into reaction with maleic anhydride and polyalkylene-polyamine. Advantageously, tetraetjylene- penaamine is used at molar ratio to isobutylene/alpha-methylstyrene copolymer between 1:1 and 3: 1. EFFECT: reduced amount of tare products in additive and improved antioxidant properties thereof. 2 cl, 4 ex
