実施例3のビス(トリメトキシシリル)エチレンの代わりに、ビス(トリエトキシシリル)エタン[下記構造式(9)]を3.75部用いた以外は同様に組成物を調製した。
次に、実施例1~5及び比較例1~4で調製した各組成物のタックフリータイムを測定した。
そして、内径が10mmのガラスシャーレに実施例1~5及び比較例1~4で調製した各組成物を充填し、23℃、50%RHで1日経過後に空気に触れた表面部分から硬化した部分までの厚さを測定し、深部硬化性を評価した。
また、実施例1~5及び比較例1~4で調製した調製直後の各組成物を厚さ2mmのシート状に押し出し、23℃,50%RHの空気に曝し、次いで、該シートを同じ雰囲気下に7日間放置して得た硬化物の物性(初期物性)を、JIS K-6249に準拠して測定した。なお、硬さは、JIS K-6249のデュロメーターA硬度計を用いて測定した。
更に、この硬化物を85℃,85%RHの恒温恒湿器に7日間保管したものを同様に測定した。また、この硬化物を150℃のオーブンで7日間加熱したものを同様に測定した。
下記に、実施例1~5及び比較例1~4の結果を表に示す。
