A new synthetic route for the preparation of alkenyl functionalized aryl cyanate ester monomers

A new, simplified synthetic route is reported for a novel family of functio nalized cyanate monomers. Importantly, the synthetic route has fewer purifi cation requirements, making it a potentially cheaper and more efficient rou te than previously reported syntheses. The products have been characterized extensively using nuclear magnetic resonance spectroscopy, infrared spectr oscopy, and elemental analysis. Bearing alkenyl groups, these materials hav e the ability to form copolymeric networks with a wide variety of monomers, to yield high performance composite matrices.
