公知の方法を用いて、スチレン/ジビニルベンゼンコポリマービーズを懸濁重合によって調製した。ジビニルベンゼンは、およそ37重量%のエチルビニルベンゼン入りで、純度63重量%であった。ビーズを、ZnCl2触媒の存在下でクロロメチルメチルエーテルと反応させて芳香環にクロロメチル基を取り付けた。生成物をトリメチルアミンと反応させて、窒素原子がクロロメチル基の炭素原子に結合する状態で、クロロメチル基の塩素原子を第四級塩化アンモニウムに変換し、樹脂(a)を生成した。
クロロメチル化反応のための触媒がFeCl3であったことを除いて、樹脂(a)を製造するための調製実施例1の手順を用いて、ビーズ(本明細書では「樹脂R1」と表示される)を調製した。次の通り、重炭酸ナトリウムの水溶液との接触、引き続く水酸化ナトリウムの水溶液との接触による洗浄によって、樹脂R1のビーズを洗浄した。
実施例1及び比較例C2からの結果として生じたビーズのナトリウム含有量を次の通り測定した。樹脂のアリコートを、電子レンジ中で硫酸での処理によって蒸解した。均一溶液が形成されるまで、混合物を加熱した。Agilent(商標)8000シリーズICP−MSを用いて、この均一溶液のアリコートを分析して以下の結果を得た。
