Title:
METHOD FOR PRODUCING PETROLEUM RESIN AND HYDROGENATED PETROLEUM RESIN
Document Type and Number:
WIPO Patent Application WO/2004/052955
Kind Code:
A1
Abstract:
A method for producing a petroleum resin, which comprises carrying out a copolymerization reaction in the presence of a cyclopentadiene type compound, a vinyl-substituted aromatic compound containing substantially no high molecular weight polymeric material and a solvent. The method allows the production of a petroleum resin and a hydrogenated petroleum resin which is reduced in the content of a high molecular weight polymeric material and has a narrow molecular weight distribution.
