Title:
VINYL ALCOHOL POLYMER
Document Type and Number:
Japanese Patent JP3618440
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a water-soluble vinyl alcohol polymer which can provide a film possessing excellent flexibility and blocking resistance by introducing a specified structural unit into the side chain of a polymer having a vinyl alcohol unit in its molecule.
SOLUTION: A vinyl ester (e.g. vinyl acetate) is copolymerized with a monomer comprising a structural unit represented by the formula (wherein R represents H, a 1-4C straight-chain or branched alkyl) (e.g. glycerol monoallyl ether). The resultant copolymer is saponified in an alcohol soln. or a dimethylsulfoxide soln. to prepare a vinyl alcohol polymer having on its side chain a structural unit represented by the formula. The content of the structural unit represented by the formula in the vinyl alcohol polymer is pref. about 0.1 to 50mol%. The vinyl alcohol polymer has good solubility in water and is useful as a coating agent for paper, an adhesive for wood, a binder for a ceramic, a coating material, a dispersion stabilizer and the like.
