Description
また、付加されるアルキレンオキサイドは、ランダム重合で付加されるため、上記化学式(1)の4つのアルキレン基(−OR−)は、それぞれが炭素数1〜4のアルキレン基であれば、同一であっても異なっていてもよいが、4つのアルキレン基がエチレン単体、又はエチレン及びプロピレンの双方のいずれかであることが好ましく、4つのアルキレン基全てがエチレンであることが特に好ましい。
上記化学式(1)において、アルキレン付加物の付加モル数は、総量として1モル以上であるが、1〜20モルが好ましく、4〜12モルがより好ましい。特に、付加されたアルキレン付加物がエチレンオキサイド単体の場合には、エチレンオキサイド4〜12モルが好ましく、4〜8モルがより好ましく、4〜6モルが特に好ましい。また、付加されたアルキレン付加物がエチレンオキサイド及びプロピレンオキサイドの場合には、エチレンオキサイド4〜8モル及びプロピレンオキサイド2〜4モルが好ましい。
次に、切断中の泡立ちを想定して、実施例1乃至実施例9に係る固定砥粒ワイヤーソー用水溶性切断液、及び比較例1乃至比較例4に係る固定砥粒ワイヤーソー用水溶性切断液を有栓式100mlメスシリンダーに50ml入れ、有栓した後、激しくシェイクし、その直後の初期泡立ち量及び泡立ちが消えるまでの消泡時間を確認した。その結果を表3に示す。なお、安定性は、25℃で1週間静置し、○:1週間分離・沈殿なし、△:4日以上、1週間未満で分離・沈殿発生、×:4日未満で分離・沈殿発生とした。
次に実施例1乃至実施例9に係る固定砥粒ワイヤーソー用水溶性切断液、並びに比較例1乃至比較例4に係る固定砥粒ワイヤーソー用水溶性切断液を使用し、表4の条件で切断試験を行い、切断したウェハーの断面曲線の最大谷高さ(PV)を測定した。結果を表5に示す。
