ABSTRACT:
Norbornenyl functional azlactone compounds of the formula: ##STR1## wherein R.sup.1 and R.sup.2 are independently monovalent hydrocarbon groups or R.sup.1 and R.sup.2, together with the carbon atom to which they are attached comprise a cyclic hydrocarbon group, are prepared by Diels-Alder addition of cyclopentadiene to vinyl azlactones. The norbornenyl azlactones are useful for preparing norbornenyl functional resins by azlactone ring opening reactions. The resulting resins may be employed as polyene components of curable thiol-ene formulations.
