    Abstract: Provided is a method for producing a petroleum resin using a tube-type reactor, the method producing a petroleum resin that exhibits good properties as an adhesive component for a hot-melt adhesive which has a narrow molecular weight distribution and a high softening point, and which exhibits good adhesive capability and also has little insoluble matter. A method of producing a petroleum resin by using a raw material containing at least a cyclopentadiene-based component (A) and a styrene-indene-based aromatic component (B) so as to carry out a thermal polymerization reaction of the raw material, the method comprising: a first polymerization reaction step of thermally polymerizing the raw material using a loop reactor; and a second polymerization reaction step of thermally polymerizing a polymerization reaction product obtained in the first polymerization reaction step using a plug flow reactor.

    Abstract: Disclosed is a method for producing a prepreg, the prepreg having: a reinforcing fiber layer including reinforcing fibers and a resin composition containing component (A), component (B), and component (C), the reinforcing fibers being impregnated with the resin composition in between the fibers; and a surface fiber layer provided on the surface of the reinforcing fiber layer and including a fabric including polyamide fibers and a resin composition containing component (A), component (B), and component (C), the polyamide fibers being impregnated with the resin composition in between the fibers. The method for producing a prepreg includes a disposition step of disposing the fabric on the surface of a reinforcing fiber base material and an impregnation step of supplying a resin composition to the reinforcing fiber base material and impregnating the reinforcing fibers with the resin composition in between the fibers.
