    摘要: A novel branched poly(3-hydroxypropionic acid)polymer of Chemical Formula 1:


    R-[A-(B)n]k  [Chemical Formula 1]

    wherein: R is a trivalent or higher functional group derived from a polyfunctional monomer: A is a direct bond, or a linking group derived from ether, sulfide, ester, thioester, ketone, sulfoxide, sulfone, sulfonate ester, amine, amide, imine, imide, or urethane; B is a substituent of Chemical Formula 1-1 or Chemical Formula 1-2:




    * is a moiety connected to A; k is an integer of 3 or more: and n is an integer of 1 to 700, and a method for preparation thereof, which makes it possible to effectively prepare a polymer that achieves an excellent production yield while maintaining the intrinsic physical properties of poly(3-hydroxypropionic acid).
