Abstract
Abstract Polymers containing a norbornenyl group are readily crosslinked by irradiation to produce insoluble products. The crosslinked products are useful as coatings on wood, metal, etc., as selfsupporting films, wire insulation, for the treatment of fabrics to render them more durable and crease resistant, as well as in the many known areas in which synthetic polymers are employed such as the production of molded and extruded shaped articles.
