Abstract
Oil-soluble polymers of N-3-aminoalkyl acrylamides, especially N-(1,1-dimethyl-3-dimethylaminopropyl)acrylamide, are obtained by copolymerization with a monomer (especially an alkyl acrylate or methacrylate) containing an alkyl group with at least about 8 carbon atoms. These polymers are useful as dispersants and viscosity modifiers for lubricants.
