Title:
METHOD FOR MANUFACTURING HYDROGENATED POLYMER
Document Type and Number:
WIPO Patent Application WO/2023/199874
Kind Code:
A1
Abstract:
The present invention provides a method for hydrogenating (nucleus-hydrogenating) an aromatic ring of an aromatic vinyl compound-based polymer in order to obtain, at a high nucleus-hydrogen addition rate, a hydrogenated polymer having sufficient heat resistance. In more detail, provided is a method for manufacturing a hydrogenated polymer by hydrogenating (nucleus-hydrogenating) an aromatic ring of an aromatic vinyl compound-based polymer, the method being characterized by comprising reducing a hydrogenation catalyst before use.
