Lubricating oil compositions containing modified succinimides (V)

专利摘要

Disclosed herein are additives which are useful as dispersants and detergents in lubricating oils and fuels. In particular, this invention is directed toward polyamino alkenyl or alkyl succinimides wherein one or more of the amino nitrogens of the succinimide is substituted withwherein R4 is hydrocarbyl of from 1 to 30 carbon atoms; R5 is hydrocarbyl of from 2 to 30 carbon atoms or -R6-(OR6)p- wherein R6 is alkylene of 2 to 5 carbon atoms and p is an integer from 1 to 100; and m is an integer of from 0 to 1. ......
