ABSTRACT:
A product is disclosed which comprises a ring-opened base polymer of at least one norbornene-type monomer and a thin polymer film on at least a portion of said base polymer of a vinylidene chloride polymer or an unsaturated nitrile polymer whereby the product has improved weatherability and reduced odor. The method of making the product is characterized by applying the polymer film from an organic solution of a vinylidene chloride resin or an unsaturated nitrile resin and then drying the coating to remove the organic solvent.
