Abstract
A method for producing a petroleum resin including removing a low-molecular mist by means of a filter.
Claims16
A method for producing a hydrogenated petroleum resin, the method comprising:
- polymerizing a cyclopentadiene-based compound and an aromatic vinyl compound, thereby obtaining a polymer;
- hydrogenating the polymer to prepare a molten hydrogenated petroleum resin;
- and
- granulating the molten hydrogenated petroleum resin, thereby obtaining hydrogenated petroleum resin pellets,
- wherein the granulating comprises sucking a low-molecular mist generated from the molten hydrogenated petroleum resin through a suction path having a filter in a granulator, and removing the low-molecular mist with the filter.
