Title:
STAR-SHAPED POLYMER, PAINT, COATING, AND METHOD FOR PRODUCING STAR-SHAPED POLYMER
Document Type and Number:
WIPO Patent Application WO/2024/020780
Kind Code:
A1
Abstract:
A method for producing a star-shaped polymer including a core portion and an arm portion includes a step of preparing an intermediate polymer by performing living radical polymerization of a monofunctional vinyl compound in the presence of a catalyst while using as an initiator a cyclodextrin skeleton-containing compound having polymerization initiation groups serving as initiation points for polymerization, to prepare an intermediate polymer including a core portion and a plurality of first blocks each including a structural unit derived from the monofunctional vinyl compound and bonded to an initiation point of the core portion; and a step of preparing a star-shaped polymer by performing living radical polymerization of a monofunctional vinyl compound as a second block constituent component in the presence of a catalyst while using the intermediate polymer as a macroinitiator, to prepare a star-shaped polymer including a plurality of second blocks each including a structural unit derived from the monofunctional vinyl compound.
