Abstract

The invention discloses a macromolecular polymerized phenol modified polydicyclopentadiene material and a preparation method thereof. The modified polydicyclopentadiene material is prepared by using dicyclopentadiene monomers, a main catalyst, a co-catalyst and macromolecular polymerized phenol as raw materials and through a reaction injection molding process, wherein a molar ratio of the dicyclopentadiene monomers to the main catalyst to the co-catalyst is 1,000-2,000:1:15-30; and the adding amount of the macromolecular polymerized phenol is 1%-10% by mass of the dicyclopentadiene. In the macromolecular polymerized phenol modified polydicyclopentadiene material, the macromolecular polymerized phenol has an anti-oxidant capacity, can generate a condensation cross-linking reaction under the effects of a dicyclopentadiene metathesis polymerization system and a catalyst, forms an interpenetrating polymer network polymer with polydicyclopentadiene, and achieves the objects of strengthening, toughening and anti-aging, so that the modified polydicyclopentadiene material has relatively high strength, toughness and anti-aging performance.
