Description
で示される四員環エーテル(オキセタン環)官能基であり、アルケニルエーテル官能基とは、下記式(2)
で示されるアルケニルエーテルからなる官能基である。
CQ:カンファーキノン。
DMPT:p−ジメチルアミノトルイジン。
DMBE:4−ジメチルアミノエチル安息香酸エチル。
条件1又は条件2の雰囲気下で、6mmφ×0.3mmの孔を有するポリテトラフルオロエチレン製のモールドの底面に、パスツールピペットを用いて硬化性組成物を塗布した。同様に組成物液面上面約5mmの距離から歯科用可視光線照射器(トクヤマデンタル社、パワーライト)にて60秒間光照射し、光硬化させた。硬化体の照射面にべたつきがある物を×、べたつきは無いが表面が白化しているものを△、べたつきおよび白化がないものを○とした。
条件1又は条件2の雰囲気下で、6mmφ×1.5mmの孔を有するポリテトラフルオロエチレン製のモールドに硬化性組成物が平らになるように充填した。雰囲気中に3分間放置し、その後、ポリプロピレンフィルムで覆い、さらにスライドグラスで圧接した状態で、充填面上5mmの位置から歯科用可視光線照射器にて60秒間光照射し、光硬化させた。硬化後、ポリプロピレンフィルムを剥がし、微小硬度計MHT−1(松沢精機株式会社製)、加重200g、加重時間30秒にて照射面の硬度を測定した。
6mmφ×1.5mmの孔を有するポリテトラフルオロエチレン製のモールドに硬化性組成物を充填し、ポリプロピレンフィルムで覆い、この未硬化の状態で分光色差計(カラーアナライザーTC−1800MK−II)を用い、黒バックにてL* 0、a* 0、b* 0を測定した。
ΔE*={(L*−L* 0)2+(a*−a* 0)2+(b*−b* 0)2}1/2
また、この試料片表面を硬化前の組成物と比較し、著しく着色している物を×、極僅かに着色している物を○、肉眼では着色が確認できない物を◎とした。
条件1の雰囲気下で硬化性組成物を2×2×25mmの金型に充填し、ポリプロピレンフィルムで覆い、光照射器にて1.5分間光照射し硬化させた。硬化物を37℃で一晩保存した後、オートグラフ(島津製作所社製)を使用し、支点間距離20mm、クロスヘッドスピード0.5mm/分で3点曲げ強度と曲げ弾性率を各々5個の硬化物について測定し、その平均値を算出した。
相対湿度20%以下の環境下でOX−1とDVE−1とを、OX−1が1モルに対して、DVE−1が0.111モルとなるように量を調節して配合した。この場合、OX−1は2官能のオキセタン化合物であるからaが2であり、DVE−1は二官能のアルケニルエーテル化合物であるからbが2であるから、(a×A):(b×B)=(2×1):(2×0.111)=90:10である。
OX−1とDVE−1との配合割合を、表1に示す官能基の割合となるよう変えた以外は実施例1と同様にして物性を評価した。結果をあわせて表1に示す。なお、表中、オキセタン化合物の欄の数値は(a×A)+(b×B)を100とした場合の(a×A)を、アルケニルエーテル化合物の欄の数値は同じく(b×B)を示す(以下、全ての表において同じ)。
重合開始剤を、IMDPIが0.1質量部、CQが0.03質量部、4−ジメチルアミノ安息香酸エチル0.03質量部とした以外は実施例1と同様にして硬化性組成物を調製し物性を評価した。結果を表2に示す。
OX−1とDVE−1との配合割合を、表1に示す官能基の割合となるよう変えた以外は実施例5と同様にして物性を評価した。結果をあわせて表2に示す。
球状シリカ−ジルコニア(粒径0.5μm)と球状シリカ−チタニア(粒径0.1μm)の重量比7:3の混合物20gを、pH4.0に調整した塩酸80mlに縣濁させ、攪拌しながら3−グリシジルオキシプロピルトリメトキシシラン1.2gを滴下した。1時間攪拌後、エバポレーターで水を留去し、得られた固体を乳鉢で粉砕後、減圧下80℃で15時間乾燥した。乾燥後、得られた粉末を無機フィラーaとし、シリカゲルを乾燥剤としたデシケーター中で保存した。
OX−1とDVE−1との配合割合を、表1に示す官能基の割合となるよう変えた以外は実施例9と同様にして歯科用充填修復材料を調製し物性を評価した。結果をあわせて表3に示す。なお、微小硬度の欄において「測定不可」とあるのは表面が極めて脆い硬化体であり、前記微小硬度計の測定下限未満の硬度であったことを表す(以下、表4、5においても同じ)。
オキセタン化合物としてOX−1に代えてOX−2を用い、表4に示す官能基割合となるようにDVE−1と混合して用いた以外は、実施例9と同様にして歯科用充填修復材料を調製し物性を評価した。結果をあわせて表4に示す。
アルケニルエーテル化合物としてDVE−1に代えてDVE−2を用い、表5に示す官能基割合となるようにOX−1と混合して用いた以外は、実施例9と同様にして歯科用充填修復材料を調製し物性を評価した。結果をあわせて表5に示す。
