Abstract: A method of manufacturing a copolymer resin of dicyclopentadiene and a vinyl aromatic compound, by which the resin can be continuously manufactured with reduced generation of high molecular weight products of the vinyl aromatic compound and insoluble substances from dicyclopentadiene, and at high yield. The manufacturing method includes continuously injecting polymerization raw materials into a preheated solvent in the reaction system, and concurrently ejecting a part of the reaction solution containing the solvent and the polymerization raw materials outside the reaction system, while raising the temperature of the polymerization raw materials. This enables rapid rise of the temperature of the polymerization raw materials by utilizing sensible heat, resulting in reduced generation of insoluble substances. In addition, providing a reaction step following the raw material injection step allows the polymerization reaction to proceed until a desired molecular weight is achieved, resulting in improved yield.
