試料粒子約1.0gを熱風乾燥機で105℃、16時間乾燥して重量を測定する(Wds[g])、次に試料粒子を温度20℃で相対湿度65%RHに調整された恒温恒湿器に24時間放置し、吸湿した試料粒子の重量を測定する(Wws[g])、以上の結果をもとに、次式により算出した。
飽和吸湿率[%]={(Wws−Wds)/Wds}×100
粒子の平均粒子径は、島津製作所製レーザー回折式粒度分布測定装置「SALD2000」を使用し、水を分散媒として測定した結果を、体積基準で表し、そのメディアン径をもって平均粒子径とした。
実施例6以外の水酸基量は、まず重合後加水分解前のサンプルの元素分析を行い、酸素原子重量比及び窒素含有量を測定することで、酢酸ビニルユニット含有量(A[mmol/g])及びアクリロニトリルユニット含有量(B[mmol/g])を求めた。その後、加水分解後のサンプルの赤外分光測定により、完全に酢酸ビニルユニット及びアクリロニトリルユニットが加水分解されていることを確認し、水酸基(ビニルアルコールユニット)と塩型カルボキシル基(アクリル酸ナトリウムユニット)に完全に変換されたものとして重量変化を求め、これらの数値より算出したものである。
原料ポリマー1gに対する酢酸ビニルユニット分の重量変化[g]
= 0.044A−0.086A = −0.042A
原料ポリマー1gに対するアクリロニトリルユニット分の重量変化[g]
= 0.094B−0.053B = 0.041B}
水酸基量[mmol/g] = A/(1−0.042A+0.041B)
塩型カルボキシル基量は、全カルボキシル基量からH型カルボキシル基量を差し引くことによって求めた。まず、十分乾燥した試料1gを精秤し(X[g])、これに200mlの水を加えた後、50℃に加温しながら1N塩酸水溶液を添加してpH2とすることで、試料に含まれるカルボキシル基を全てH型カルボキシル基とし、次いで0.1N水酸化ナトリウム水溶液で常法に従って滴定曲線を求めた。該滴定曲線からH型カルボキシル基に消費された水酸化ナトリウム水溶液消費量(Y[ml])を求め、次式によって試料中に含まれる全カルボキシル基量を算出した。
全カルボキシル基量[mmol/g]=0.1Y/X
別途、上述の全カルボキシル基量測定操作中の1N塩酸水溶液添加によるpH2への調整をすることなく同様に滴定曲線を求め、試料中に含まれるH型カルボキシル基量を求めた。これらの結果から次式により塩型カルボキシル基量を算出した。
塩型カルボキシル基量[mmol/g]=(全カルボキシル基量)−(H型カルボキシル基量)
耐水性評価用サンプルは、ポリイソシアネート(バーノックDN−980K、DIC社製)6.5g、試料粒子5g、ポリオール(アクリディックA−801−P、DIC社製)23.5gを混合しPETフィルムにバーコーター#50で塗工した後に、130℃で30分乾燥させたものを用いた。耐水性評価は上記サンプルを水に10分間浸漬させた後に表面の水分を拭き取り、塗工部分に白化が見られるかどうかを目視で判断し、白化が見られた場合を×、白化が見られなかった場合を○とした。
吸湿性発現率は、上記の飽和吸湿率(A[%])、上記の耐水性評価サンプルにおける試料粒子の含有量(B[g/m2])及び吸湿量(C[g/m2])、耐水性評価サンプルと試料粒子を添加しないこと以外は同様にして塗工して得られたブランクサンプルの吸湿量(D[g/m2])を測定し、次式により算出したものである。なお、吸湿量CおよびDについては、上記の飽和吸湿率の項と同様の方法で測定した。
吸湿性発現率(%)=[(C−D)/B×100]/A×100
試料粒子40部およびウレタン樹脂(スーパーフレックス(登録商標)E−4800、第一工業製薬社製)100部を混合し、ナイロンメッシュ(200メッシュ)上にガラス棒を用いて50μmの厚さで塗工し、室温で乾燥する。得られた塗工布について、JIS L 1099(A−1法)に基づき透湿度を測定する。
アクリロニトリル74部、酢酸ビニル1部、ジビニルベンゼン25部からなるモノマー混合液を、0.5部の過硫酸アンモニウムを含む水溶液300部に添加し、次いでピロ亜硫酸ナトリウム0.6部を加え、攪拌機つきの重合槽で65℃、2時間重合する。得られたポリマーをろ過して水洗する。次に該ポリマー100部を10%水酸化ナトリウム水溶液567部に添加し、95℃で48時間加水分解反応を行った。次いで、得られたポリマーをろ過、水洗して吸湿性微粒子1を得た。該粒子の評価結果は表1のとおりであり、耐水性は良好であった。また、耐水性評価で用いたサンプルについて吸湿性発現率を測定したところ90.7%以上であった。
実施例1において、モノマー混合液として、アクリロニトリル75部、ジビニルベンゼン25部からなるものを用いた以外は実施例1と同様に操作して吸湿性微粒子2を得た。該粒子の評価結果は表1のとおりであり、水に浸漬することにより白化した。
実施例1において、モノマー混合液として、アクリロニトリル64部、酢酸ビニル1部、ジビニルベンゼン35部からなるものを用いた以外は実施例1と同様に操作して吸湿性微粒子3を得た。該粒子の評価結果は表1のとおりであり、耐水性は良好であった。
実施例1において、モノマー混合液して、アクリロニトリル65部、ジビニルベンゼン35部からなるものを用いた以外は実施例1と同様に操作して吸湿性微粒子4を得た。該粒子の評価結果は表1のとおりであり、水に浸漬することにより白化した。
実施例1において、モノマー混合液として、アクリロニトリル56.7部、酢酸ビニル8.3部、ジビニルベンゼン35部からなるものを用いた以外は実施例1と同様に操作して吸湿性微粒子5を得た。該粒子の評価結果は表1のとおりであり、耐水性は良好であった。
実施例1において、モノマー混合液として、アクリロニトリル5部、酢酸ビニル60部、ジビニルベンゼン35部からなるものを用いた以外は実施例1と同様に操作して吸湿性微粒子6を得た。該粒子の評価結果は表1のとおりであり、耐水性は良好であった。
実施例1において、モノマー混合液として、アクリロニトリル10部、酢酸ビニル65部、ジビニルベンゼン25部からなるものを用いた以外は実施例1と同様に操作して吸湿性微粒子7を得た。該粒子の評価結果は表1のとおりであり、耐水性は良好であった。
メタクリル酸10部、4−ヒドロキシルブチルアクリレート3部、アクリロニトリル62部、ジビニルベンゼン25部からなるモノマー混合液を、0.5部の過硫酸アンモニウムを含む水溶液300部に添加し、次いでピロ亜硫酸ナトリウム0.6部を加え、攪拌機つきの重合槽で65℃、2時間重合する。得られたポリマーをろ過して水洗する。洗浄液をガスクロマトグラフィーで分析することで、ポリマー中のメタクリル酸、4−ヒドロキシルブチルアクリレートの導入量を求めた。次にポリマー100部を2%炭酸ナトリウム水溶液567部に添加し、30℃で4時間カルボキシル基の中和反応を行った。次いで、得られたポリマーをろ過、水洗して吸湿性微粒子8を得た。該粒子の評価結果は表1のとおりであり、耐水性は良好であった。なお、このときの水酸基量に関しては、上記ガスクロマトグラフィー分析で求めたメタクリル酸ユニット(A[mmol/g])の理論的な中和反応による重量変化と、上記ガスクロマトグラフィー分析で求めた4−ヒドロキシルブチルアクリレートユニットの導入量(B[mmol/g])から算出したものである。
原料ポリマー1gあたりのメタクリル酸ユニット分の重量変化[g]
= 0.108A−0.086A = 0.022A
水酸基量[mmol/g] = B/(1+0.022A)
5gの吸湿性微粒子1、ビスフェノールAジグリシジルエーテル27.8g、ジシアンジアミド2.2g、ジメチル尿素0.8gを混合しPETフィルムにバーコーターで塗工した後に、120℃で30分乾燥させることによって、エポキシ樹脂に吸湿性微粒子1に添加したサンプルを作成する。かかる測定サンプルを用い、上記と同様にして耐水性と吸湿性発現率を評価した。該サンプルは水に浸漬した後も白化せず、良好な耐水性を示した。また、吸湿性発現率も85.1%と良好であった。
またp−シアノイソシアン酸フェニル(和光純薬製)1部を50部のメチルエチルケトンに溶解し、吸湿性微粒子1を2部加えて80℃で12時間攪拌させた後、粒子をろ過、アセトンで3回洗浄し、50℃で12時間乾燥させた微粒子9を得た。該粒子の赤外吸収スペクトルを図2、吸湿性微粒子1の赤外吸収スペクトルを図1に示す。図2には図1に見られないシアノ基に由来する2241cm−1、ウレタン結合を示す1739cm−1に吸収が確認される。すなわち、吸湿性微粒子1とp−シアノイソシアン酸フェニルを反応させて得られた微粒子9にはウレタン結合とシアノ基が導入されており、このことより、吸湿性微粒子1の水酸基がイソシアネート基と反応して共有結合が形成されることが理解される。
参考例1において、吸湿性微粒子1の代わりに吸湿性微粒子2を用いたこと以外は同様にして操作を行ない、微粒子10を得た。該粒子の赤外吸収スペクトルを図4、吸湿性微粒子2の赤外吸収スペクトルを図3に示す。図3、図4はほぼ同様のスペクトルであり、水酸基を持たない吸湿性微粒子2はイソシアネート基と反応しないことが理解される。
