METHOD FOR PRODUCING HOMOPOLYMERIZED PRODUCT OF PHOSPHORUS-BASED ACID RESIDUE-CONTAINING UNSATURATED MONOMER, USE OF THE HOMOPOLYMERIZED PRODUCT, METHOD FOR PRODUCING SOLUTION OF THE HOMOPOLYMERIZED PRODUCT AND USE OF THE SOLUTION OF THE HOMOPOLYMERIZED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a polymerized product solely composed of a phosphorus-based acid residue-containing unsaturated monomer by solution polymerization without gelling.;SOLUTION: The method for producing the polymerized product solely composed of a phosphorus-based acid residue-containing unsaturated monomer containing at least one phosphorus-based acid residue and at least one ethylenically unsaturated bond in the molecule by solution polymerization comprises using an aliphatic lower alcohol containing 0.1 to 35 mass%, based on 100 mass% entire solvent, water as a solvent and making the concentration of the above phosphorus-based acid residue-containing unsaturated monomer to 14 mass% based on 100 mass% entire polymerization solution.;COPYRIGHT: (C)2005,JPO&NCIPI
