Title:
ALIPHATIC POLYCARBONATE RESIN, CROSSLINKED ALIPHATIC POLYCARBONATE RESIN, METHODS FOR PRODUCING SAME, AND ADHESIVE SHEET
Document Type and Number:
WIPO Patent Application WO/2024/070798
Kind Code:
A1
Abstract:
Provided is an aliphatic polycarbonate resin having an ether structure in a main chain thereof, and having a structure in which a repeating unit represented by formula (Ia), a repeating unit represented by formula (Ib), a repeating unit represented by formula (Ic), and a repeating unit represented by formula (Id) are randomly copolymerized. Accordingly, it is possible to provide a novel aliphatic polycarbonate resin and a crosslinked aliphatic polycarbonate resin, which have a low glass transition temperature (Tg) and use carbon dioxide as a raw material. (In formula (Ia) and formula (Ib), R1 and R2 are hydrocarbon groups having at least 4 carbon atoms, and may be the same as or different from each other. In formula (Ic) and formula (Id), R3 and R4 are hydrocarbon groups having a crosslinkable functional group, and may be the same as or different from each other.)
