PROBLEM TO BE SOLVED: To provide a phosphate-modified vinylic polymer excellent in balance of conductivity, water resistance and solvent resistance and to provide a method for producing the polymer. SOLUTION: At least one kind of hydroxy group-containing vinylic (co)polymer selected from the group consisting of an unsaturated alcohol-based copolymer containing at least an unsaturated alcohol unit and a fatty acid vinyl unit and/or a halogen vinyl unit and a partially acetalized unsaturated alcohol-based polymer is reacted with a phosphoric acid source compound and water to provide the phosphate-modified vinylic polymer excellent in balance of conductivity, water resistance and solvent resistance.
