Heavy metal deactivator/inhibitor for use in olefinic polymers

摘要

An olefine polymer composition comprises a stabilizing amount of a metal deactivator comprising a polymeric hydrazine derivative. The deactivator is of formula (I), in which at least one of R1 and R2 comprise a polymeric radical that includes a substituted or unsubstituted aromatic radical, provided that R1 and R2 are not both of formula (II). The olefin polymers include polyethylene and polypropylene.
