Norbornenyl azlactones
First Claim
1. A curable thiol-ene composition comprising a polyene, a polythiol and an initiator of thiol-ene addition reactions wherein the polyene component comprises a compound having a plurality of groups of the formula:
- ##STR10## wherein R1 and R2 are independently monovalent hydrocarbon groups or R1 and R2, together with the carbon atom to which they are attached comprise a cyclic hydrocarbon group R3 is --NR4 --, --S--, or --O-- and R4 is H or alkyl.

Abstract
Norbornenyl functional azlactone compounds of the formula: ##STR1## wherein R1 and R2 are independently monovalent hydrocarbon groups or R1 and R2, 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.
