Abstract:
1. A method for making a vinyl polymer having a terminus to which a functional-group-introducing agent is added, comprising: supplying the functional-group-introducing agent having a low polymerizability and a functional-group-introducing solvent having a dielectric constant higher than that of the functional-group-introducing agent to a polymerization system after 80 percent by weight or more of a vinyl monomer is consumed by atom transfer radical polymerization in a polymerization solvent in the presence of a polymerization initiator and a transition metal complex functioning as a polymerization catalyst, and adding the functional-group-introducing agent to the terminus of the vinyl polymer by addition reaction, wherein 1 to 1,000 parts by weight of the functional-group-introducing solvent to 100 parts by weight of the vinyl monomer is supplied.
