Method for producing polyvinyl alcohol resin |
| abstract |
Provided is a method of producing a polyvinyl alcohol resin, wherein the impurities in the resin are removed efficiently with a small amount of a washing liquid. n A polyvinyl alcohol obtained after a polymerization step (step S1) and a saponification step (step S2) is washed with a washing liquid consisting of methyl acetate: 1 to 40 parts by mass, methanol: 50 to 98.9 parts by mass and water: 0.1 to 10 parts by mass in a washing step (step S3). The solid matter concentration of the slurry containing the washing liquid then is 1 to 30 mass %. |
