| abstract | (57) [Summary] [Structure] The following structural units (I), (II) and (II I), the content of (I) is 0.5 to 30.0 mol%, and the content of (II) is 99.4 to 50.0 mol%. And the content of (III) is 0.1 to 20.0 mol%, The total amount of (I) and (III) is 0.6 to 50.0 mol%, and the weight average molecular weight is 3,000 to 400,000. Modified polyvinyl alcohol which is 0. [Chemical 1] (In the formula, R represents H or CH 3 , and M 1 and M 2 represent H, alkali metal, ammonium, alkylammonium, and alkanolammonium, respectively.) Effect The modified polyvinyl alcohol of the present invention is dispersed. It is a novel water-soluble polymer compound having excellent performance, having resistance to divalent metal ions, and excellent in reducing dehydration of mud water, and is useful as a dispersant or a mud water regulator for excavation. |
