Functionalized degradable ROMP (ring-opening metathesis) polymers and methods, starting monomers and synthetic monomeric and polymeric intermediates for preparation of such functionalized polymers. More specifically, monomers having a bicyclic oxazinone structure, a bicyclic urea, or a heteronorbornene core structure, among others, have been found to be substrates for ROMP polymerization. ROMP polymers prepared from these monomers have been found to be both acid and base labile. Additionally, the monomers can be chemically modified at a site distal to the polymerizable moieties and bridgehead carbons. The properties of the resulting polymers and copolymers can be tailored without destabiling the monomer. Polymers and copolymers of the invention are degradable but have a glass temperature of 100° C. or more.

ROMP: A heterobicyclic olefin containing an oxazinone core is a new substrate for the ring‐openingmetathesispolymerization (ROMP). The polymers produced undergo degradation when exposed to either acidic or basic conditions. Furthermore, a monomer that can be readily diversified to access degradablepolymers bearing tailored functionality was developed.
