Abstract: Acrylate graft copolymers prepared in a two-stage process by first reacting a backbone polymer, such as 1,2-polybutadiene, an alkylidene norbornene polymer or an ethylene/propylene/alkylidene norbornene terpolymer, with, for example, a mixture of dinitrogen tetroxide and oxygen to form a nitrooxidized polymer having incorporated therein nitro and peroxy nitrate functions which serve, in the second stage of the process, as sites for the subsequent graft polymerization of an acrylate monomer are disclosed. The thus-formed graft copolymers comprise from about 5 to about 80 weight percent of the backbone polymer with the balance being furnished by the acrylate monomer.

Abstract: A machine frame includes a pair of upstanding frame members interconnected by a pair of telescopic members which include a power cylinder for moving the upstanding members towards and away from each other. A bead breaker arm includes a pair of hooks on one end, the bottom of which pivotally engages a pin on one of the upstanding members while the other hook movably engages another pin spaced above the first pin to allow the arm to move vertically within limits defined by the hook and the opposite end of a curved surface along which the second pin engages as the arm is raised and lowered. The outer free end of the arm includes a pivotal wedge member having an upwardly curved tapered end for engaging the rim and moving between the tire bead and the rim. The other upstanding frame member includes a rim holder for limiting the rim against vertical movement.

Abstract: Lubricating compositions exhibiting an improved viscosity index are prepared by adding to a lubricating oil base stock a small amount of graft copolymer of a methacrylate ester and an ethylene/propylene/alkylidene norbornene terpolymer.

Abstract: Lube oil, characterized by improved properties, may be prepared containing polymers having pendant N-hydrocarbylcarboxamide groups - typically N-(N',N'-dihydrocarbylaminohydrocarbyl) carboxamide groups.

Abstract: Amino ester products, useful as additives to lubricating oils, may be prepared by reaction of an alpha-nitroketone and a tertiary aminoalcohol.
