Abstract
【解決手段】アミジン構造を含有する水溶性高分子の安定な油中水滴型エマルジョンと多官能性単量体および/または架橋性単量体の存在下共重合したアミジン構造を含有しない水溶性高分子の安定な油中水滴型エマルジョンの混合物である安定な油中水滴型エマルジョン組成物およびこれを用いた汚泥の脱水方法を提供する。
【選択図】なし
Description
R1は水素又はメチル基、R2、R3は炭素数1〜3のアルキルあるいはアルコキシル基、R4は水素、炭素数1〜3のアルキル基、アルコキシル基あるいはベンジル基であり、同種でも異種でも良い、Aは酸素またはNH、Bは炭素数2〜4のアルキレン基またはアルコキシレン基を表わす、X1−は陰イオンをそれぞれ表わす。
R5は水素又はメチル基、R6、R7は炭素数1〜3のアルキル基、アルコキシ基あるいはベンジル基、X2−は陰イオンをそれぞれ表わす。
R8は水素、メチル基またはカルボキシメチル基、QはSO3 −、C6H4SO3 −、CONHC(CH3)2CH2SO3 −、C6H4COO−あるいはCOO−、R9は水素またはCOO−Y1 +、Y+およびY1 +は水素イオンまたは陽イオン
加水分解に用いる塩基としては、水溶液中で塩基性を示すものであれば特に制限はないが、水酸化ナトリウム、水酸化カリウムなどアルカリ金属の水酸化物を用いることが好適である。また加水分解の際ゲル化を防止するため水酸化アンモニウムやヒドロキシルアミン塩を添加することが好適である。
