摘要： There are disclosed a viscosity index improver comprising a polymer containing at least 70% by weight of structural units of an alkyl (meth)acryrate monomer containing not more than 10 carbon atoms in the alkyl group, and a lubrication oil, comprising said improver added to a lubrication base oll selected from the group consisting of mineral oils, MLDW oils, iso-paraffin-containing high viscosity index oils, synthetic hydrocarbon lubricating oils, synthetic ester lubricating oils, and mixture of two or more of these. The improver exhibits improved low-temperature viscosity characteristics and oxidation resistance, as compared with conventional methacrylate polymer viscosity index improvers. It gives extremely low viscosity at -40.degree. C., particularly when used in high viscosity index oils. Besides, when used in conjunction with a molybdenum-containing FM agent, it has a characteristic of providing low friction coefficient even after oxidative degradation. Thus, lubricating oil, prepared using the improver, shows improved low-temperature flow properties and oxidative stability at high temperature, and are usable even under severe circumstances and of improved reduced fuel cost.

摘要： An oil-soluble lubricating oil additive useful as a dispersant, comprising Mannich Base condensates of an alkyl (hydrocarbon or polymer) substituted hydroxy aromatic compound with an aldehyde and a heavy polyamine. A heavy polyamine is a mixture of polyalkylenepolyamines comprising small amounts of lower polyamine oligomers such as tetraethylene pentamine and pentahexamine but primarily oligomers with 7 or more nitrogens, 2 or more primary amines per molecule, and more extensive branching than conventional polyamine mixtures.

摘要： A blend and a process for producing that blend in which a high ethylene content ethylene-propylene polymer and a lower ethylene content ethylene-propylene polymer are subjected to simultaneous blending and shearing to reduce their molecular weights and molecular weight distribution and to yield a product that can be recovered as a solid using conventional plastic processing equipment. The sheared blend of polymers can function as a shear stable viscosity index improver with improved lower temperature properties.
