SUCCINIC ACID OR SUCCINIC ANHYDRIDE SUBSTITUTED WITH HYDROCARBON HAVING ASYMETRIC MOLECULAR WEIGHT - POLYAMINE LUBRICANT ADDITIVE

摘要

There are disclosed oil-soluble alkenyl succinimides having improved sludge dispersant and varnish inhibition properties characterized in that the alkenyl groups, e.g., polyisobutenyl, have a C60 - C80 average and have an asymmetrical molecular weight distribution with minimization of the presence of radicals below C40.
