摘要： 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.

摘要： A resin composition that enables formation of a film superior in cold water solubility, mechanical strength, and chemical resistance is provided. The resin composition comprises a modified PVA comprising a monomer unit represented by formula (I), and an amine compound represented by formula (II): €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒH 2 N€”R 5 €ƒ€ƒ€ƒ€ƒ€ƒ(II) a content of the amine compound with respect to 100 parts by mass of the modified PVA being from 0.01 parts by mass to 1 part by mass. In the formula (I), R 1 represents a hydrogen atom, or an alkyl group having 1 to 8 carbon atoms; 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 having 1 to 10 carbon atoms, X + representing a hydrogen atom, a metal atom, or an ammonium group, and R 4 representing a linear or branched alkyl group having 1 to 5 carbon atoms. In the formula (II), R 5 represents -R 3 '-SO 3 - X + ', -R 3 '-N + (R 4 ') 3 Cl - , or a hydrogen atom.
