| description | Provided by the present invention is a vinyl alcohol polymer crosslinked by a structure represented by the following formula (1) and/or a disulfide structure, in which the vinyl alcohol polymer is not completely dissolved in a mixture prepared by: adding the vinyl alcohol polymer to water so as to give a concentration of 4% by mass; and stirring at 95° C. for 3 hrs. in the formula (1), R1, R2 and R3 each independently represent a hydrogen atom or a substituted or unsubstituted hydrocarbon group having 8 or less carbon atoms. Also provided include an additive for a drilling mud containing the vinyl alcohol polymer, a drilling mud containing the vinyl alcohol polymer as an additive, an additive for a drilling cement slurry containing the vinyl alcohol polymer, and a drilling cement slurry containing the vinyl alcohol polymer as an additive. |
