Title:
STAR POLYMER, COATING MATERIAL, COATING FILM, AND METHOD FOR PRODUCING STAR POLYMER
Document Type and Number:
WIPO Patent Application WO/2022/236548
Kind Code:
A1
Abstract:
A star polymer includes a core portion and an arm portion that is a polymer chain attached to the core portion. The arm portion has a functional group at a distal end thereof, the arm portion has a number average molecular weight of 10,000 or more as measured by gel permeation chromatography (GPC (RI)), and the star polymer has a number average molecular weight of 100,000 or more as measured by gel permeation chromatography (GPC (RI)).
