Abstract:
A lubricant additive prepared by the method comprising:(a) mixing a polmer consisting of a polymerized ethylene and at least one (C.sub.3 -C.sub.10) alpha-monolefin, with methyl acrylamido-glycolate methyl ether to form poly [(ethylene-c-alpha-mono-olefin) -graft-(methyl acrylamido glycolate methyl ether)];(b) reacting said poly (methyl acrylamido glycolate methyl ether) with an amino aromatic compound to form the corresponding poly [(ethylene-co-alpha monolefin)-graft-(methyl acryl amidoglycolate)] aromatic amide; and(c) recovering said aromatic amide lubricant additive product.
