Description
上記（ｉ－１）において、アンモニウム基を有するモノマーとしては特に制限はないが、例えばジアリルジメチルアンモニウムクロライド、ビニルトリメチルアンモニウムクロライド、アリルトリメチルアンモニウムクロライド、ｐ－ビニルベンジルトリメチルアンモニウムクロライド、３－（メタクリルアミド）プロピルトリメチルアンモニウムクロライドが挙げられる。また、上記アンモニウム基を有するモノマーの誘導体としては、該モノマーのアミン等が挙げられ、例えば、ジアリルメチルアミン、ビニルアミン、アリルアミン、ｐ－ビニルベンジルジメチルアミンおよび３－（メタクリルアミド）プロピルジメチルアミン等が用いられる。 In the above (i-1), the monomer having an ammonium group is not particularly limited, and for example, diallyldimethylammonium chloride, vinyltrimethylammonium chloride, allyltrimethylammonium chloride, p-vinylbenzyltrimethylammonium chloride, 3- (methacrylamide). ) Propyltrimethylammonium chloride. Examples of the derivative of the monomer having an ammonium group include amines and the like of the monomer, and examples thereof include diallylmethylamine, vinylamine, allylamine , p-vinylbenzyldimethylamine and 3- (methacrylamide) propyldimethylamine . Used.
ビニルアルコール系重合体（Ａ）の粘度平均重合度に特に制限はないが、製造容易性の観点から、好ましくは２００００以下、より好ましくは１００００以下、さらに好ましくは４０００以下、特に好ましくは３０００以下である。一方、ビニルアルコール系重合体（Ａ）の力学特性および水への耐溶出性の観点からは、好ましくは１００以上、より好ましくは２００以上、さらに好ましくは４００以上である。ビニルアルコール系重合体（Ａ）の粘度平均重合度は、例えばＪＩＳ Ｋ ６７２６に準拠した方法により測定できる。ビニルアルコール系重合体（Ａ）が後述のように架橋構造を有する場合、例えばビニルアルコール系重合体（Ａ）が架橋構造としてアセタール構造またはエステル構造を有する場合、粘度平均重合度の測定は、架橋構造を切断した後に行うことができる。前記切断は、一般的な方法（例えば、酸若しくはアルカリを用いた加水分解）により行うことができる。
The viscosity average degree of polymerization of the vinyl alcohol polymer (A) is not particularly limited, but is preferably 20000 or less, more preferably 10000 or less, still more preferably 4000 or less, and particularly preferably 3000 or less from the viewpoint of ease of production. be. On the other hand, from the viewpoint of the mechanical properties of the vinyl alcohol polymer (A) and the elution resistance to water, it is preferably 100 or more, more preferably 200 or more, still more preferably 400 or more. The viscosity average degree of polymerization of the vinyl alcohol polymer (A) can be measured, for example, by a method according to JIS K 6726. When the vinyl alcohol -based polymer (A) has a crosslinked structure as described later, for example, when the vinyl alcohol -based polymer (A) has an acetal structure or an ester structure as a crosslinked structure, the measurement of the viscosity average degree of polymerization is carried out. It can be done after cutting the structure. The cutting can be carried out by a general method (for example, hydrolysis using an acid or an alkali).
