| titleOfInvention | Method for producing hydrophilic polymer |
| abstract | (57) [Problem] To find a method for obtaining a hydrophilic polymer by a simple process from a monomer component containing a water-soluble monomer and a poorly water-soluble monomer. A method for producing a hydrophilic polymer from a poorly water-soluble monomer and one or more water-soluble monomers by solution polymerization, wherein the poorly water-soluble monomer is dissolved in water at 50 ° C. Solubility 5 % By weight, and an ethylenically unsaturated group and a group directly connected to a carbon atom of the ethylenically unsaturated group are -R 1- [C HR 2 (CH 2 ) m O] n -R 3 [where R 1 is -C OO -, - CH 2 COO - , - CONH -, - CHCO NH—, —NH—, — (CH 2 ) p NH— (where p is 1 to 4) and — (CH 2 ) q O— (where q is 1 to 4), and R 2 is hydrogen Or a methyl group, m is 1 3, n represents 1 to 60, and R 3 represents a hydrophobic group containing 4 or more carbons. And a method for producing a hydrophilic polymer using, as a polymerization solvent, a hydrophilic solvent having a solubility in water at 25 ° C. of 10% by weight or more, or a mixed solvent of the hydrophilic solvent and water. It is. |
