    摘要: Crude oils having high pour points, mineral lubricating oils and fuel oils are improved in one or more of their characteristics such as their dispersancy, pour point, viscosity and viscosity index characteristics by the addition of a copolymer of (a) a monomeric aziridineethyl acrylate or methacrylate and (b) a monomeric alkyl ester of acrylic or methacrylic acid whose alkyl substituent contains 8 to 18 carbon atoms, said copolymer having a molecular weight of at least about 20,000 and a mole ratio of (a):(b) within the range of about 1:2 to about 1:99, respectively, e.g., aziridineethyl methacrylate:lauryl methacrylate (1:19).
