Azidoaryl-substituted cyclooctene monomers and synthesized and used in the
preparation of various copolymers. Among these copolymers are those
prepared from ring-opening metathesis polymerization of cyclooctene,
polyethylene glycol-substituted cyclooctene, and azidoaryl-substituted
cyclooctene. These copolymers are useful in the formation of crosslinked
films that reduce fouling of water purification membranes.
