ABSTRACT:
Polymer comprising cyclopentanedioxocarbonyl vinylene units are prepared by ring opening metathesis polymerization of the endo stereoisomer of norbornene dioxocarbonyl monomer. Such polymers prepared in bulk or solution are useful as engineering thermoplastics for injection molding and solution casting. Such polymers can also be polymerized in molds.
