PROBLEM TO BE SOLVED: To provide a method for simply and easily producing a phosphate ester monomer including a high-purity phosphate monoester at high yield.SOLUTION: There is provided a method for production of a phosphate monoester monomer represented by formula (1) (Ris H or methyl; Ris 2-4C alkylene group; and n is an integer of 1 to 30) comprising reacting hydroxyalkyl (meth)acrylate and/or alkylene oxide adduct thereof with polyphosphoric acid under the presence of N,N'-dimethylformamide. There is also provided a method for production of a phosphate ester monomer including blending polyphosphoric acid with DMF, adding hydroxyalkyl (meth)acrylate and/or alkylene oxide adduct thereof, reacting, and hydrolyzing a reaction product.SELECTED DRAWING: None 【課題】リン酸モノエステルの純度が高いリン酸エステル系モノマーを高収率で簡便に製造方法の提供。【解決手段】Ｎ，Ｎ'−ジメチルホルムアミド（ＤＭＦ）の存在下、ヒドロキシアルキル（メタ）アクリレート及び／又はそのアルキレンオキサイド付加物物と、ポリリン酸とを反応させる、式（１）で表されるリン酸モノエステル系モノマーの製造方法。ポリリン酸とＤＭＦとを混合し、ヒドロキシアルキル（メタ）アクリレート及び／又はそのアルキレンオキサイド付加物を添加し、反応させ、反応生成物を加水分解することにより、リン酸エステル系モノマーの製造方法。（Ｒ１はＨ又はメチル基；Ｒ２はＣ２〜４のアルキレン基；ｎは１〜３０の整数）【選択図】なし
