摘要

A complex product of (1) an interpolymer of dialkylaminoalkyl methacrylate, C1-C6 alkyl methacrylate, C10-C14 alkyl methacrylate and C16-C20 alkyl methacrylate monomers and (2) a liquid alkylbenzene of a molecular weight between about 100 and 5000, prepared by polymerizing the monomers comprising said interpolymer in the presence of said liquid alkylbenzene. A mineral oil composition of improved viscosity, pour depressing and detergent-dispersant properties and concentrates thereof comprising between about 10 and 95 wt. % of a mineral oil of lubricating viscosity and between about 0.1 and 90 wt. % of said complex product.
