Cyclic olefin copolymers (COC) are important plastic materials due to their high heat resistance, high hydrophobicity and excellent optical properties.Ethene (E)-norbornene (NBE) copolymer is a well-known COC material.The glass transition temperature (Tg) of E-NBE copolymer can be controlled easily by comonomer composition, but the copolymer is fragile.
