Abstract: A modified dicyclopentadiene-based resin is provided. The modified dicyclopentadiene-based resin is formed from a dicyclopentadiene-based resin having an amino group, a phenol and a polyoxymethylene by a cyclization reaction. The dicyclopentadiene-based resin having an amino group is formed by nitration reaction and hydrogenation reaction of dicyclopentadiene phenolic resin.

Abstract: A modified maleimide resin is provided. The modified maleimide resin is formed from a dicyclopentadiene (DCPD)-based resin having an amino group and a maleic anhydride by a condensation polymerization. The dicyclopentadiene-based resin having an amino group is formed by nitration and hydrogenation of dicyclopentadiene phenolic resin.

Abstract: A modified dicyclopentadiene-based resin and a preparation method thereof are provided. The preparation method of the modified dicyclopentadiene-based resin includes sequentially performing nitration reaction and hydrogenation reaction of a dicyclopentadiene phenolic resin to form a modified dicyclopentadiene-based resin for which the structure has at least two amino groups. The hydrogenation reaction is performed in a solvent at a temperature of 50° C. to 120° C.
