Description
(A)下記一般式(1)
かつ、酸性基を有するラジカル重合性単量体及び下記一般式(2)
なお、これら酸性基を有するラジカル重合性単量体、及び上記一般式(2)で示されるラジカル重合性単量体は、前記一般式(1)で示される化合物中の不純物として不可避的に混入してくる場合もある(例えば、メタクリル酸など)。本発明においては、これらラジカル重合性単量体が一般的な不純物量以上に含まれなければよく、通常、全ラジカル重合性単量体中、2質量%以下、好ましくは1質量%以下、特に好ましくは0.5質量%以下であればよい。不純物として含まれる量が極めて多い場合には、水や塩基性水溶液で洗浄することにより、これら酸性基を有するラジカル重合性単量体や上記一般式(2)で示されるラジカル重合性単量体は容易に除去できる。
ホウ素−アリール結合を全く有しないボレート化合物は保存安定性が極めて悪く、空気中の酸素と容易に反応して分解するため好ましくない。ホウ素−アリール結合が多いほど、保存安定性に優れたものとでき、トリアリールボレート塩又はテトラアリールボレート塩が好ましく、テトラアリールボレート塩が最も好ましい。

(II)固体酸のpKa評価法
固体酸のpKa評価はハメット試薬の呈色により行なった。ハメット試薬は有機色素群であり、各々の試薬溶液へ固体酸を入れると該固体酸のpKa値に応じた発色をする。各ハメット試薬の変色するpKa値は既にわかっているので、各試薬溶液へ固体酸を入れて発色を観察することにより、その固体酸のpKa値の範囲を知ることができる。
製造例1(SA−1の製造)
強酸性陽イオン交換樹脂(三菱化学社製:ダイヤイオンPK228)をカラムに詰め、1モル/リッターの塩酸水溶液で洗浄して該樹脂中に含まれる金属イオンを除去した。続いて蒸留水により洗浄して余剰の塩酸を除去した。洗浄された樹脂は、減圧下、60℃で恒量となるまで乾燥して粉砕に用いた。樹脂の粉砕は、まず磁性乳鉢にて1次粉砕した後、粉砕によって得られる粉末の平均粒径が10μmになるまでメノウ乳鉢を用いてさらに粉砕した(以下、この粉末をSA−1)。この粉末のpKaを評価したところ、pKaは0.8よりも小さかった。またこの固体酸SA−1の酸当量は2.4meq/gであった。
ラジカル重合性単量体100gに対してPhB3.0gの割合で混合し、室温にて10分間磁気攪拌子を用いて攪拌した。攪拌停止後、液の性状を目視により判定した。液が透明で、沈殿もない場合を○、液が白濁あるいは沈殿が生じた場合を×とした。
作製した粉および液を粉液の質量比が2:1となるよう混和してペーストを作製し、該ペーストを口腔内で5分間保持することにより評価を行なった。評価は、○が問題なく口腔内で保持できる。△が保持はできるが不快感を強く感じる。×が口腔内で保持していられないほど問題がある。の3段階で評価した。
組成物の硬化性は、粉4gに対し、液2gの割合で混合したペーストを20×20×2mmの窪みのあるポリテトラフルオロエチレン製モールドへ流し込み、空気に接した面をポリエチレンシートで圧接して37℃で1時間硬化させた。得られた硬化体をモールドから取り出し、37℃の蒸留水中で24時間吸水させた。得られた硬化体のうち、硬度が計測できるほどの硬さに硬化したサンプルに関しては、松沢精機製微小硬度計で100gf、20秒荷重印加の条件でヌープ硬度を測定した。硬度が測定できるほど硬化しなかったサンプルあるいは全く硬化しなかったものに関しては×印で表記した。
粉液を混ぜた直後のペーストの色調から、硬化後の硬化体の色調変化を5段階のスコアで評価した。また、該硬化体を80℃水中に30日間保存し、保存前後の硬化体の変色度合いも同様に評価した。
スコア3 黄色に変色
スコア2 わずかに黄色に変色
スコア1 白濁するのみ
スコア0 変化なし
(VIII)硬化体表面の面荒れ評価
硬化体表面の面荒れは、粉4gに対し、液2gの割合で混合したペーストを20×20×2mmの窪みのあるポリテトラフルオロエチレン製モールドへ流し込み、片面を開放したまま37℃の温水中で1時間硬化させた。得られた硬化体の水に接した面の目視および指によるざらつき評価を行なった。表面が滑沢である場合には○、表面が著しくざらついている場合には×で評価した。
10gのCHDに対して0.3gの割合でPhBを溶解し、液成分とした。PhBは完全に溶解して透明な溶液となった。200ml容量のチャック付きポリ袋に20gのEMAおよび0.4gのSA−1を入れ、乾燥空気で袋を膨らませた状態でチャックを閉じ、袋を10分間振ることによりSA−1をEMAに分散させた。
表1に示した組成で液および粉を作製した以外は実施例1と同様な評価を行なった。その結果、実施例1と同様な良好な結果が得られた。
PhBおよびSA−1からなる重合開始剤成分の代わりにBPOおよびPEATを用いた以外は実施例1と同様な評価を行なった。その結果、液性状、官能試験および硬化体硬度は良好であったが、硬化時に黄変が起こり、さらに80℃保存した硬化体は褐色に変化した。
ラジカル重合性単量体としてPMを用い、PhBを粉に配合した以外は実施例1と同様の評価を行なった。その結果、粉および液混合後のペーストが強い酸味を呈しており口腔保持ができなかった。また、硬化体表面の面荒れも著しかった。
CHDの代わりに表2に示したラジカル重合性単量体を使用した以外は、実施例1と同様な方法で評価を行なった。この場合、液は濁って懸濁したままであり、PhBの殆どが溶解していなかった。液をよく振り、懸濁液を秤量して、実施例1と同様な評価を行なった。その結果、重合による硬化は起こらず、粉が液に部分溶解した餅状のままであった。
CHDの代わりにHE又はHEとHDの混合物を用いた以外は実施例1と同様の評価を行なった。実施例1と同様な方法で評価を行なった。この場合、液は濁って懸濁したままであり、PhBの殆どが溶解していなかった。液をよく振り、懸濁液を秤量して、実施例1と同様な評価を行なった。その結果、重合による硬化は起こらず、粉が液に部分溶解した餅状のままであった。
CHDやBPE−1の代わりに3Gまたは3GとHDの混合物を用いたこと以外は実施例1と同様の評価を行なった。その結果、硬化体の硬度や変色に関しては良好な結果が得られたが、ペーストの味が著しく苦く、硬化まで口腔挿入していられなかった。
CHDやBPE−1の代わりに14Gを用いたこと以外は実施例1と同様の評価を行なった。その結果、ペーストの味が苦く、硬化まで口腔挿入していられなかった。硬化によって硬化体は得られたものの、その硬度は極めて低く、硬度測定ができなかった。さらに、硬化体表面の面荒れが著しいことがわかった。
CHDの代わりに14GとHDの混合液を用いた以外は、実施例1と同様の評価を行なった。その結果、比較例12の組成と比較して、硬化体硬度は改善されたものの、苦味や硬化体表面の面荒れは改善されなかった。
CHDの代わりにHEMAまたはHEMAとHDの混合液を用いたこと以外は実施例1と同様の評価を行なった。その結果、ペーストの臭い、味、刺激、硬化体硬度および硬化体の変色に関しては良好であったが、硬化体表面が著しく面荒れした。
CHD50質量部と、3G、14G又はHEMA50質量部の混合液を用いたこと以外は実施例1と同様の評価を行なった。その結果、いずれの場合にも3G、14G又はHEMAを単独で用いた場合と同様の問題を生じた。
