Abstract

Resins which are the copolymers of an alpha-olefin, a cyclic olefin, and an aromatic-group-containing monomer are provided. The cyclic olefins retain their cyclic structures and the aromatic-group-containing monomers retain their aromatic structures after copolymerization into the resin product. Methods for production of the new resins in the presence of a metallocene catalyst system are also provided. New adhesive compositions containing the resin and articles using the new adhesive compositions are also part of the invention.
