    • A series of mono, bi and tricarbocyclic compounds, most of which have olefinic unsaturation in the ring, which may or may not have substituents thereon. While the bi and tricyclic rings may be unsubstituted, these compounds which have olefinic unsaturation, particularly multiple olefinic unsaturation, are polymerizable and copolymerizable in known polymerization systems. They are particularly good crosslinking agents. These compounds are further useful in the sense that they can be cleaved oxidatively, to corresponding carboxylic acids, aldehydes and/or alcohols which have known utility in the plasticizer and detergent arts. The compounds which do not have olefinic unsaturation can also be oxidatively cleaved to produce oxygenated, e.g., acid, alcohol or aldehyde, compounds having known utility.
    • 一系列单环,双和三环化合物,其中大多数在环中具有烯属不饱和键,其可以具有或不具有取代基。 虽然双环和三环可以是未取代的,但是具有烯属不饱和键,特别是多个烯属不饱和键的这些化合物在已知的聚合体系中是可聚合的和可共聚的。 它们是特别好的交联剂。 这些化合物在它们可以被氧化裂解的意义上可进一步用于在增塑剂和洗涤剂领域已知有用的相应的羧酸,醛和/或醇。 不具有烯属不饱和键的化合物也可被氧化裂解以产生氧化的,例如酸,醇或醛,已知有用的化合物。
