Norbornene polymers containing bound phenolic antioxidant

Claim 1

A polymeric composition of matter comprising a reaction product obtained by ring opening polymerization using a metathesis catalyst of a norbornene-type monomer and 0.05 to 10 parts by weight per 100 parts of said norbornene-type monomers of a norbornenyl phenolic antioxidant defined as follows: ##STR6## where R 1 , R 2 , and R 3 are individually selected from hydrogen and alkyl groups of 1 and 3 carbon atoms; R 4 is selected from hydrogen, alkyl groups containing 1 to 12 carbon atoms, and alicyclic groups of 4 to 8 carbon atoms; R 5 is selected from alkyl groups of 1 to 6 carbon atoms, and alicyclic groups of 4 to 8 carbon atoms; R 6 is selcted from alkylene and alkenylene groups containing 1 to 8 carbon atoms; and R 7 is selected from hydrogen, alkyl and alkenyl groups of 1 to 8 carbon atoms, amount of said norbornenyl phenolic being sufficient to improve antioxidant properties of said reaction product.
