    摘要: 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. The disclosed compositions and methods generally provide longer shelf lifes and better oxidative resistance to materials than currently available antioxidants.

    摘要: Compounds are synthesized that contain nitrogen and hindered phenol functionalities of an aromatic amine and hindered phenol for use as oxidative stabilizers for organic materials, paints, lubricants, elastomers, and in other applications. The disclosed methods can efficiently synthesize target monomers and polymers without the use of expensive catalysts. Further, the disclosed methods can scale up to industrially useful quantities. In general, the methods provide an improved, highly efficient and economical process for the synthesis of macromonomers having nitrogen containing moiety and sterically hindered phenols and their corresponding polymers.
