A first object of the present invention is to provide a vinyl polymer that has a molecular chain into which a structure containing a polar functional group is introduced, and that is useful as a precursor of a graft polymer. A second object of the present invention is to provide a process for producing the vinyl polymer. These objects can be achieved by the present invention providing a vinyl polymer having a polar functional group (X), and further having, at the position of at least one molecular terminal thereof, a group (A) containing a carbon-carbon double bond.
