Abstract

See full text

A process is provided for the preparation of a graft copolymer compatibilizer useful at low levels for blending with separately prepared olefin copolymers and polymethacrylate polymers to form a stable, concentrated, polymer blend. The polymer blend, as well as the compatibilizer, are useful lubricating oil additives concentrates which contain at least 80 weight percent polymethacrylate segments. The polymer blend may be further diluted with a hydrocarbon oil to form a lubricating fluid. The polymer blend offers the benefit of the thickening power of olefin copolymers, the low temperature viscosity characteristics of polymethacrylates, and is stable for prolonged periods without phase separation.
