Abstract:
Provided are a method for producing a multibranched polymer that can produce a multibranched polymer having a narrow molecular weight distribution in a one-pot procedure and the multibranched polymer. A method for producing a multibranched polymer includes the step of polymerizing a first vinyl monomer having a polymerization-initiating group in an α-position of a vinyl bond and a second vinyl monomer free of polymerization-initiating group in an α-position of a vinyl bond by a living radical polymerization.
