Description
温度計、還流冷却管及び窒素導入管を備えた四つ口フラスコにアクリルアミド100部(モノマー総モル和に対し91.1モル%)、62.5%硫酸7.2部、ジメチルアミノエチルメタクリレート14.6部(6.0モル%)、80%アクリル酸水溶液 2.8部(2.0モル%)、N,N−ジメチルアクリルアミド0.8部(0.5モル%)、メタリルスルフォン酸ナトリウム1.0部(0.4モル%)、及びイオン交換水440部を仕込み、窒素ガスを通じて反応系の酸素を除去した。系内を61℃にし撹拌下に重合開始剤として過硫酸アンモニウム0.23部及び亜硫酸水素ナトリウム0.1部を投入した。90℃まで昇温した後、2時間保温した。重合終了後、尿素120部、イオン交換水520部を投入し、pH3.7、濃度20%、粘度4000cpsの両性ポリアクリルアミド水溶液を得た(1)。このようにして得られたポリマーに25%燐酸15.2部を添加し、pH2.4に調整した。
実施例1と同様の反応器にアクリルアミド100部(モノマー総モル和に対し90.6モル%)、70%ジメチルアミノエチルメタクリレートのベンジルクロライド4級化物34.6部(5.5モル%)、イタコン酸6.1部(3.0モル%)、N,N−ジメチルアクリルアミド0.8部(0.5モル%)、メタリルスルフォン酸ナトリウム1.0部(0.4モル%)、及びイオン交換水480部を仕込み、実施例1と同様に重合を行なった。重合終了後、尿素120部、イオン交換水510部を投入し、pH3.8、濃度20%、粘度3500cpsの両性ポリアクリルアミド水溶液を得た(2)。このようにして得られたポリマーに25%燐酸15.8部を添加し、pH2.4に調整した。
実施例1と同様の反応器にアクリルアミド100部(モノマー総モル和に対し89.2モル%)、75%ジメチルアミノエチルアクリレートのベンジルクロライド4級化物22.7部(4.0モル%)、イタコン酸12.3部(6.0モル%)、N,N−ジメチルアクリルアミド0.8部(0.5モル%)、メタリルスルフォン酸ナトリウム0.7部(0.3モル%)、及びイオン交換水490部を仕込み、実施例1と同様に重合を行なった。重合終了後、尿素120部、イオン交換水500部を投入し、pH3.9、濃度20%、粘度3900cpsの両性ポリアクリルアミド水溶液を得た(3)。このようにして得られたポリマーに25%燐酸15.2部を添加し、pH2.4に調整した。
表1に記載の成分を変更した他は、実施例1と同様にして表1に記載の各両性ポリアクリルアミドを得た。得られたポリマーに25%燐酸15.2部を添加し、表1に記載のとおり調整した。
実施例1〜3で得た燐酸添加前の両性ポリアクリルアミド水溶液(1)〜(3)にそれぞれ硫酸を混合し、pH2.4の水溶液を調製した。
実施例1〜3で得た燐酸添加前の両性ポリアクリルアミド水溶液(1)〜(3)にそれぞれ塩酸を混合し、pH2.4の水溶液を調製した。
尿素を添加しない以外は、比較例1と同様にして両性ポリアクリルアミド水溶液を調整し、これに燐酸を混合し、pHを2.5の水溶液を調整した。
ジメチルアミノエチルメタクリレートを添加しない以外は、比較例2と同様にして両性ポリアクリルアミド水溶液を調整した(pH3.9)。
カチオン価残存率は30℃で1ヶ月経過後のサンプルのカチオン価を調整直後のサンプルのカチオン価で除算することで求めた。カチオン価はサンプルを塩酸にてpH2.0とした後、トルイジンブルーを指示薬として1/400規定(N)のポリビニル硫酸カリウム水溶液によりコロイド滴定によって測定した。
段ボール古紙をナイアガラ式ビーターにて叩解し、カナディアン・スタンダード・フリーネス(C.S.F.)350mlに調整したパルプに硫酸バンドを1%添加した後、攪拌し均一に混合した。得られたパルプスラリーを0.5%まで希釈し、手抄紙試験機により水分量80%の湿紙を調製した。湿紙の片面に、実施例、比較例で得た抄き合わせ紙用添加剤をイオン交換水で0.2%に希釈した液を、パルプ固形分に対して0.5%となる割合でスプレー塗布した後、紙力剤塗布面ともう1方の湿紙とを重ね、乾燥して抄き合わせ紙を得た。得られた抄き合わせ紙を24時間調湿後、J−TAPPI紙パルプ試験方法No.19−77に従って層間接着強度(T字剥離強度(g/in))を測定、またJIS P8131に従って比破裂強度を測定した。
