Transparent polymers with good optical properties have attracted significant attention due to their application potential in many areas. Among many transparent polymers, cyclic olefin polymers have excellent transparency, high thermal stability, and low birefringence. For automotive applications, high glass transition temperature is critical because it is directly related to the thermal stability required for end use. COPs are mainly synthesized through ROMP of cycloolefins followed by subsequent hydrogenation of remaining double bonds in the polymer backbone. Herein, we report the ROMP of DCPD containing a functional group (eDCPD). The epoxy functional group was introduced into an allylic position of the cyclopentene ring not only to prevent the crosslink reaction during the polymerization of DCPD but also to enhance the thermal properties of the COPs. Introduction of a polar functional group and a bulky comonomer is expected to improve the adhesion and thermal properties of COPs.
