ABSTRACT:
Oil-soluble dispersants are formed by reacting (i) at least one aliphatic hydrocarbyl substituted succinic acylating agent in which the hydrocarbyl substituent contains an average of at least 40 carbon atoms with (ii) a mixture consisting essentially of hydrocarbyl polyamines containing from 10 to 50 weight percent acyclic alkylene polyamines and 50 to 90 weight percent cyclic alkylene polyamines. Such dispersants exhibit improved compatibility with fluoroelastomers as compared to succinimides formed from conventional alkylene polyamine mixtures predominating in acyclic isomers.
