| titleOfInvention | Polymeric lubricating oil additives |
| abstract | Polymers and copolymers useful as lubricating oil additives are prepared by polymerizing an ester of an unsaturated tri-carboxylic acid wherein at least one of the ester groups comprises a saturated alkyl group having at least 8 carbon atoms and preferably not more than 22 carbon atoms with or without an ethylenically unsaturated copolymerizable monomer. Specified as copolymerizable monomers are vinyl esters, e.g. vinyl acetate, vinyl halides, vinyl ethers, vinylidene halides, vinyl ketones, maleates, fumarates, acrylates, e.g. methyl acrylate, methacrylates, butadiene and styrene. Benzoyl peroxide may be used as a catalyst and the reaction is best carried out in an inert atmosphere, e.g. of nitrogen, at a temperature of 80 DEG C. Specified acids are aconitic, methylaconitic, and a -g -D -butene tri-carboxylic acid and the alcohols from which the esters are prepared may be particularly the mixed alcohol obtained from the hydrogenation of coconut oil. |
