Abstract
Disclosed are an additive composition comprising a graft and amine-derivatized copolymer prepared from ethylene and at least one C3-C10 alpha-monoolefin and, optionally, a polyene selected from non-conjugated dimes and trienes comprising from about 15 to 80 mole percent of ethylene, from about 20 to 85 mole percent of the C3-C10 alpha-monoolefin and from about 0 to 15 mole percent of the polyene having an average molecular weight ranging from about 1,000 to 40,000 which has been reacted with at least one olefinic carboxylic acid acylating agent to form one or more acylating reaction intermediates characterized by having at least about 1.5 weight percent of a carboxylic acid acylating function within their structure and reacting the reaction intermediate with an amino-aromatic polyamine compound from the group consisting of an N-arylphenylenediamine, an aminothiazole, an aminocarbazole, an aminoindole, an aminopyrrole, an amino-indazolinone, an aminomercaptotriazole, and an aminoperimidine to form the graft and amine-derivatized copolymer, and a lubricating oil composition containing same.
