Transparent polymers with good optical properties have attracted significant attention due to their potential in a wide range of applications, including optical storage device, optical fiber, sheet product, camera lenses, projection displays and diffractive optical lenses. Among many transparent polymers, cyclic olefin polymers have excellent transparency, good chemical resistance, and low birefringence. However, for automotive applications, high glass transition temperature is necessary because it is directly related to the thermal stability required for end use. COPs are mainly synthesized through ROMP of cycloolefin followed by subsequent hydrogenation of remaining double bonds in the polymer backbone. The hydrogenation enhances the chemical resistance and heat resistance of COPs obtained by ROMP, but decreases the glass transition temperature due to the increased backbone flexibility. Herein, we report the functionalization of COPs to enhance the thermal properties of COPs. |
