ABSTRACT:
The present invention provides for polymeric stabilizers which are the acid-catalyzed reaction product of a phenolic compound or a ring substituted aromatic compound and an olefin polymer containing either terminal unsaturation and/or pendant unsaturation along the polymer chain. These stabilizers are readily compatiable with olefin polymer and copolymer matrixes and offer good protection of the matrix polymer against one or more of heat, oxygen, ultra violet or radiation degradation. Other advantages include low volatilization as well as low tendency to migrate from the polymer matrix.
