    摘要: A polymeric article which is subject to attack by oxygen ozone and/or ultraviolet light is coated with a thin coating of a polymer which is resistant to oxygen, ozone and UV light. It protects the article from cracking or degradation due to any of these causes. The uncoated article serves as a substrate. The substrate may be any polymer which is subject to attach by oxygen, ozone and/or ultraviolet light. A preferred coating is cured from a highly saturated polymer having only a small amount of unsaturation, as for example, hydrogenated nitrile rubber (HNBR, or hydrogenated nitrile/butadiene copolymer), highly saturated styrene/butadiene copolymer, hydrogenated polybutadiene, or hydrogenated styrene/vinylpyridine/butadiene terpolymer. The hydrogenated or highly saturated polymer of the coating is obtained by hydrogenating an unsaturated polymer which is a polymer of 1,3-butadiene (5-100% by weight) and optionally one or more monoethylenically unsaturated polymers (0-95% by weight). The cured coatings are typically elastomeric. The coating is applied as an uncured highly saturated polymer latex, which is dried and cured in place on the substrate to yield the desired coated article. The thickness of the coating may be about 0.5 mil (0.0005 inch) up to approximately 10 mils (0.01 inch).
