The present invention provides a method for forming a polymer by using a mixture containing a polymerization initiator which is an adduct of a boron compound and a first unsaturated hydrocarbon compound, and a second unsaturated hydrocarbon compound, generating a radical by oxidization of the polymerization initiator and adding the radical to the second unsaturated hydrocarbon compound, thereby forming the polymer. According to the present invention, excellent controllability of alkylboranes for radical polymerization can be maintained and the structure of a polymerization initiation terminal can be freely selected and controlled. Thus, a terminal-modified polymer having functionality imparted to the terminal group can be prepared. In addition, a polymerization initiator having a plurality of polymerization starting points can be prepared, and polymers with special structures including multibranched polymers, grafted-type (comb-type) polymers and brush-shaped polymers can be prepared.
