(JA) ポリビニルアルコール系架橋共重合体
Abstract
(EN)
The present invention relates to a polyvinyl alcohol-based crosslinked copolymer containing an unsaturated monocarboxylic acid-based constituent unit, wherein the amount of constituent units forming a carboxylate in the crosslinked copolymer relative to the total amount of the constituent units constituting the crosslinked copolymer is 1 to 35% by mole and the solubility in water is 90% or less.
