The present invention relates to the preparation of a new class of materials, namely, an acrylate terminated or end-capped urethane/urea copolymer containing silicone soft segments capable of dual cure via unsaturated groups and dialkoxyl silanol groups. This new class of material is a reaction product of a partially methacrylated end-capped urethane polymer containing hard segment blocks and an amino alkylene dialkoxy end-capped siloxane block polymer, containing soft-segments. The aminoalkylene dialkoxysilane end-capped siloxane segment of this copolymer can include siloxane diol segments of various molecular weights (e.g., 1,000 to 20,000) end-capped with various alkylaminoalkylene trimethoxy silanes. This copolymer is therefore capable of dual cure via these functional groups.

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.
