    摘要： Provided is a method for producing a hydrogenated petroleum resin having good compatibility with a base polymer and a good hue under a hydrogen pressure of 4 MPaG or less.
    A method for producing a hydrogenated petroleum resin, includes a hydrogenation step of hydrogenating a polymerization product of dicyclopentadiene and a vinyl aromatic compound in the presence of a catalyst, in which the hydrogenation step is performed under conditions (A) to (C) below:
    (A) an amount of the catalyst used: 0.125 to 0.4 parts by mass relative to 100 parts by mass of a resin in the polymerization product;
    (B) a reaction pressure: 4 MPaG or less; and
    (C) a reaction temperature: 240°C or higher.

    摘要： This invention provides a method of manufacturing a curable petroleum resin and a curable petroleum resin obtained therefrom. The method includes (a) a process of thermally polymerizing a composition for polymerization which includes silanes and monomers, including cyclic olefins having at least one ethylenically unsaturated group selected from among C5 fractions, C9 fractions, and dicyclopentadiene of naphtha cracking, thereby enabling petroleum resins, which are thermoplastic resins, to be applied as reactive adhesives, and ultimately being capable of providing eco-friendly reactive adhesives.
