ABSTRACT:
A polymer comprising at least one polymer chain is produced by polymerizing, in the presence of a radical generating source and an iodide compound, at least one monomer M.sub.1 having a radically polymerizable unsaturated bond between a carbon atom and an iodine atom constituting a carbon-iodine bond of the iodide compound to form at least one polymer chain between the carbon atom and the iodine atom, wherein the polymerization reaction is carried out in the presence of a monomer M.sub.2 which is different from the monomer M.sub.1 and has a larger addition reactivity with a carbon radical which is generated by cleavage of the carbon-iodine bond of the iodine compound than that of the monomer M.sub.1.
