Document Type and Number:
WIPO Patent Application WO/2020/235442
Kind Code:
A1
Abstract:
Provided are: a graft copolymer in which a backbone polymer is an aliphatic polycarbonate and a branch polymer is a polymer of a radical-copolymerizable monomer; a method for producing the graft copolymer; and a precursor for a graft copolymer. The graft copolymer of the present invention is a graft copolymer having a backbone polymer and a branch polymer bonded to the backbone polymer, wherein the backbone polymer is an aliphatic polycarbonate and the branch polymer is a polymer of a radical-polymerizable monomer. The precursor of the present invention is a precursor for a graft copolymer, wherein a backbone polymer is an aliphatic polycarbonate and the aliphatic polycarbonate has a structural unit containing a functional group having a controlled radical polymerization initiation ability.
