Abstract:
A modified PVA that enables formation of a film superior in cold water solubility, mechanical strength, and chemical resistance is provided. The modified PVA comprises a monomer unit represented by formula (I), and a structural unit represented by formula (II): wherein: a content of the monomer unit (I) is from 0.05 mol % to 10 mol %, and a content of the structural unit (II) is from 0.001 mol % to 0.5 mol % with respect to the total monomer units in the modified PVA; a viscosity average degree of polymerization is from 300 to 3,000; and a degree of saponification is from 82 mol % to 99.5 mol %. In the formula (I): R 1  represents a hydrogen atom, or a methyl group; and R 2  represents —R 3 —SO 3 − X + , —R 3 —N + (R 4 ) 3 Cl − , or a hydrogen atom, R 3  representing an alkanediyl group, X +  representing a hydrogen atom, a metal atom, or an ammonium group, and R 4  representing an alkyl group.

Claim (Index 12):
The modified polyvinyl alcohol according to  claim 1 , wherein in the formula (II) R 5  represents a linear or branched alkyl group having 1 to 8 carbon atoms.
