Abstract
A method for manufacturing a graft polymer, that ensures more stable progress of a living radical polymerization by using a monomer structural unit containing an iodine initiating group as an initiator, includes performing a living radical polymerization of a compound with a vinyl monomer by an organic catalyst to manufacture the graft polymer. The compound has a recurring unit represented by a formula (1) below in a main chain: where, R: linking group (linear, branched, or cyclic alkylene group having 1 to 30 carbon atoms that may contain an ether bond, an amide bond, or an ester bond, an aromatic group), R, R, R, R, R: an aromatic group, an aliphatic group, a hydrogen atom, an aliphatic group, and n=1 to 5.
