MANUFACTURING METHOD FOR POLYMER HAVING THIOCARBONYLTHIO GROUP REMOVED

Document Type and Number:

WIPO Patent Application WO/2022/210254

Kind Code:

A1

Abstract:

Provided is a manufacturing method for a polymer having a thiocarbonylthio group removed, said method comprising a step for removing a thiocarbonylthio group from a polymer by radiating light onto a mixture containing a polymer, that has a thiocarbonylthio group at the end of a main chain, and at least one hydroxyl group-containing compound of an alcohol compound and a phenol compound.
