Abstract: Adhesive composition and articles are described comprising a carrier substrate (e.g. release liner or backing) and an adhesive composition disposed on the carrier substrate. The adhesive composition comprises at least 20 wt.% of a polymer; unpolymerized cyclic olefin; and a (e.g. latent) ring opening metathesis polymerization catalyst or precatalyst thereof. The polymer may have a Tg less than 25° C. and/or may be an acrylic polymer. Also described is a method of bonding.

Abstract: Benzotriazole phenols with substituents either ortho to the phenol hydroxyl group and/or para to the phenol hydroxyl group can be prepared from the unsubstituted benzotriazole phenol by coupling reactions. The ortho substituent group can be a simple alkoxy or amino group, or the ortho substituent group can be a linking group, linking the benzotriazole phenol to another benzotriazole phenol group.
