Described are antioxidant macromolecules and methods of making and using same.

Macromolecular antioxidants comprising differing antioxidant moieties: structures, methods of making and using the same

Compositions comprise first antioxidants and first additives, such as, a surface additives, performance enhancing additives and lubricant protective additives and optionally second additives and/or second antioxidants. The compositions are useful to improve lubricants, lubricant oils and other lubricant materials. The compositions and methods generally provide longer shelf lives, increased oxidative resistance, improved quality and/or enhanced performance to lubricants or lubricant oils.

Lubricant oil compositions

Disclosed are compounds represented by structural formula (I): methods of producing compounds represented by structural formula (I). and their use in inhibiting oxidation in an oxidizable material.

Nitrogen and hindered phenol containing dual functional macromolecular antioxidants: synthesis, performances and applications

A polymer is characterized by a repeat unit represented by Structural Formula (I): or a copolymer thereof. A crosslinked polymer characterized by a repeat unit represented by Structural Formula (II), (III), (IV) or (V): or a copolymer thereof, wherein at least one such repeat unit of a first polymer strand is crosslinked with at least one repeat unit of a second polymer strand by at least one bridging unit, the first and second polymer strands and the repeat unit being components of the crosslinked polymer.

Mixed organic and inorganic polymers

A sterically hindered phenol and phosphite based compound represented the following formula: and its use as an antioxidant in a wide range of materials including, but not limited to, food, plastics, elastomers, composites and petroleum based products is disclosed herein.

Macromolecular antioxidants based on sterically hindered phenols and phosphites

Disclosed are compositions comprising antioxidants and stabilizers, such as, acid scavengers or organic phosphorus stabilizers, and optionally further comprising co-stabilizers. The disclosed compositions are useful as stabilizers for polyolefins and other polymeric materials.
