An improved process for producing a vinyl or vinylidene polymer comprising polymerizing a monomer having a vinyl or vinylidene group in the presence of
(a) a radical polymerization initiator,
(b) an organic phosphorus compound of the formula:
wherein R¹, R² and R³ are independently hydrogen atom, chlorine atom, bromine atom, an alkyl, an aralkyl, or an aryl,
(c) an amine hydrohalide or a quaternary ammonium halide, and
(d) a copper-containing compound, which can be carried out rapidly and can give the vinyl or vinylidene polymer having excellent mechanical strength without coloring.
