Abstract
A cyclic olefin polymer synthesized by ring opening metathesis polymerization (ROMP) has a high cis double bond content. Such polymers can exhibit advantageous mechanical properties. A polymer composite includes a first domain of a polymer having a high cis double bond content and a second domain of a polymer having a high trans double bond content. Methods for the manufacture of high cis content cyclic olefin polymers and composites thereof are also provided.
