摘要：
Provided is a new method that effectively reduces odor components that are present in a hydrogenated petroleum resin, and adjusts a softening point to an appropriate range for exhibiting an adhesive performance.
A method for deodorizing a hydrogenated petroleum resin, includes stripping a hydrogenated petroleum resin at a gas flow rate of 1 to 45 WM.
