Abstract: L-1593 TITLE: NOVEL CARBOXYLIC ACID ACYLATING AGENTS, DERIVATIVES THEREOF, CONCENTRATE AND LUBRICANT COMPOSITIONS CONTAINING THE SAME, AND PROCESSES FOR THEIR PREPARATION INVENTOR: Norman Anthony Meinhardt and Kirk Emerson Davis Carboxylic acid acylating agents are derived from polyalkenes such as polybutenes, and a dibasic, carboxylic reactant such as maleic or fumaric acid or certain derivatives thereof. These acylating agents are characterized in that the polyalkenes from which they are derived have a Mn value of about 1300 to about 5000 and a Mw/Mn value of about 1.5 to about 4. The acylating agents are further characterized by the presence within their structure of at least 1.3 groups derived from the dibasic, carboxylic reactant for each equivalent weight of the groups derived from the polyalkene. The acylating agents can be reacted with a further reactant subject to being acylated such as polyethylene polyamines and polyols (e.g., pentaerythritol) to produce derivatives useful per se as lubricant additives or as intermediates to be subjected to post-treatment with various other chemical compounds and compositions, such as epoxides, to produce still other derivatives useful as lubricant additives.
