This invention relates to a cycloolefin copolymer, which is prepared via ring-opening metathesis polymerization using, as monomers, dicyclopentadiene obtained by chemically bonding two cyclopentadiene molecules using a Diels-Alder reaction and tricyclopentadiene obtained by chemically bonding three cyclopentadiene molecules using a Diels-Alder reaction, in which the cyclopentadiene is a C5-fraction of naphtha cracking, and to a method of preparing the same. This copolymer is a non-crystalline transparent resin and is useful for a variety of end uses.

Cycloolefin polymer compound and method of preparing the same

A cycloolefin-based copolymer and a hydrogenation process are disclosed, wherein the cycloolefin-based copolymer is prepared by using: a monomer which can be easily and economically obtained by hydrogenating dicyclopentadiene that occupies much of C5 fractions from naphtha cracking; or a monomer which can be obtained by chemically bonding three molecules of cyclopentadiene via Diels-Alder reactions and then hydrogenating the cyclopentadiene. The copolymer can be used in various fields as an amorphous transparent resin.
