| titleOfInvention | (Meth) acrylic acid water-soluble polymer |
| abstract | PROBLEM TO BE SOLVED: To provide an industrially useful (meth) acrylic acid type which can achieve both excellent calcium resistance and thickening, has an insoluble content sufficiently reduced, and can be suitably used for many applications. A water-soluble polymer is provided. SOLUTION: (Meth) acrylic acid (salt) monomer (A) 60-95 mol%, the following general formula (1); CH 2 = C (R) -COOZ 1 (O) p Z 2 OX (1) (In the formula, R represents a hydrogen atom or a methyl group. Z 1 and Z 2 are the same or different and represent an alkylene group having 8 or less carbon atoms. X represents a hydrocarbon group having 4 or less carbon atoms. P represents an integer of 0 or 1.) The (meth) acrylate monomer (B) represented by 5 to 40 mol%, and the monomers (A) and (B) A monomer containing 0 to 35 mol% of another copolymerizable monomer (C) (provided that the total amount of monomers (A), (B) and (C) is 100 mol%). A water-soluble polymer obtained by polymerizing components, wherein a 0.2% by mass aqueous solution has a viscosity of 10 mPa ยท s or more, an insoluble content of 5% by mass or less, and a calcium resistance of 5 ml or more (meth). Acrylic acid water-soluble polymer. [Selection figure] None |
