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 lives and better oxidative resistance to materials than currently available antioxidants.
摘要:
Disclosed are macromolecular antioxidants represented by a structural formula selected from I-VI: and polymeric macromolecular antioxidants comprises at least one repeating unit represented by a structural formula selected from VIIa, VIIb, VIIIa, VIIIb or a combination thereof: possessing superior oxidative resistance and higher thermal stability than commercially available antioxidants, and synthesis and applications of these macromolecular antioxidants and polymeric macromolecular antioxidants.
摘要:
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.
