Method for preparing dicyclopentadiene-based resin and dicyclopentadiene-based resin

The present invention relates to a method for preparing a dicyclopentadiene-based resin and a dicyclopentadiene-based resin. According to the present invention, a dicyclopentadiene-based resin can be provided having improved product quality by using a comonomer containing an aromatic olefin as a comonomer; the compatibility is high, the color characteristic is good, and the softening point is low; and the invention has improved adhesive strength due to low molecular weight and molecular weight distribution. 本发明涉及一种制备基于二环戊二烯的树脂的方法以及基于二环戊二烯的树脂。根据本发明，可以提供一种基于二环戊二烯的树脂，其通过包含基于芳香族烯烃的共聚单体作为共聚单体而具有改善的产品质量，包括高的相容性、良好的颜色特性和低的软化点，并且由于低的分子量和分子量分布而具有改善的粘合强度。
