N-VINYL CYCLIC LACTAM POLYMER, PRODUCTION METHOD THEREOF, AND APPLICATION THEREOF |
摘要 |
<p>To provide: an N-vinyl cyclic lactam polymer, which has excellent dispersibility and adsorptivity, and high calcium-ion capturing capability and can be preferably used in, for example, a detergent additive application; an application thereof; and a production method of the N-vinyl cyclic lactam polymer, the production method being capable of efficiently producing such an N-vinyl cyclic lactam polymer. An N-vinyl cyclic lactam polymer produced by a polymerization of a monomer component containing a carboxyl group-containing unsaturated monomer with a polymer having an N-vinyl cyclic lactam unit, wherein the carboxyl group-containing unsaturated monomer is 200 to 9900 parts by weight, relative to 100 parts by weight of the polymer having an N-vinyl cyclic lactam unit, and the N-vinyl cyclic lactam polymer has a viscosity at 25 °C of 100000 mPa·s or less in an aqueous solution with a solid content of 25% by weight.</p> |
