Title:
PRODUCTION METHOD FOR HYDROGENATED PETROLEUM RESIN
Document Type and Number:
WIPO Patent Application WO/2018/168654
Kind Code:
A1
Abstract:
Provided is a novel production method for hydrogenated petroleum resins, which is for producing a hydrogenated resin based on dicyclopentadiene and a vinylaromatic compound, the hydrogenated resin being for use as a tackifier. The production method is free from filter clogging and makes it possible to inhibit the catalytic activity from considerably decreasing during hydrogenation.
The method for producing a hydrogenated petroleum resin based on dicyclopentadiene and a vinylaromatic compound comprises reacting a dicyclopentadiene compound with a vinylaromatic compound, thermally polymerizing the resultant reaction product to obtain a thermal polymerization product, and thereafter hydrogenating the thermal polymerization product, and is characterized in that a dicyclopentadiene oligomer is removed from the thermal polymerization product and the thermal polymerization product from which the oligomer has been removed is used as a feed material to be hydrogenated.
