ABSTRACT:
A process is provided for the polymerization of 7-oxanorbornene and its derivatives. The process involves the ring opening metathesis of 7-oxanorbornene and its derivatives, preferably using water as the solvent. Such materials may be homopolymerized or, alternatively, copolymerized with other cyclic olefins such as norbornene. The resulting polymers are also novel.
