Title:
METHOD FOR PRODUCING HYDROGENATED PETROLEUM RESIN
Document Type and Number:
WIPO Patent Application WO/2019/189295
Kind Code:
A1
Abstract:
A method is provided by which a hydrogenated petroleum resin having satisfactory compatibility with base polymers and a good hue can be produced at a hydrogen pressure of 4 MPaG or less. The method for producing a hydrogenated petroleum resin comprises a hydrogenation step in which a product of the polymerization of dicyclopentadiene with a vinylaromatic compound is hydrogenated in the presence of a catalyst, the hydrogenation step being conducted under the conditions of (A) to (C). (A) The catalyst is used in an amount of 0.125-0.4 parts by mass per 100 parts by mass of the resin contained in the polymerization product. (B) A reaction pressure of 4 MPaG or lower. (C) A reaction temperature of 240°C or higher.
