上記NaOH水溶液洗浄工程で得られた有機相に、0.2mol/LのHCl水溶液を水相比で15容量%となるように加え、500rpmで10分間撹拌した。撹拌後に得られた溶液を内径4.2cm、高さ40cmの円筒型ガラス容器に満たし、所定時間経過後の、下から20cmの位置の有機相(ポリカーボネート-ポリオルガノシロキサン共重合体を含む塩化メチレン溶液)を採取し、その有機相中の水分量を前記方法により測定した。経過時間ごとの有機相中の残存水分量をプロットすることで経過時間と有機相中の残存水分量との関係式を求め、その関係式から有機相中水分が1.5質量%に到達するまでの時間(分)を求めた。
その後、有機層を全量採取し、遠心機(日立工機(株)製「CF6L」)を用いて3000rpmで5分間遠心分離し、分離した水分を除去して有機相を得た。
上記HCl水溶液洗浄工程で得られた有機相に、純水を水相比で15容量%となるように加え、500rpmで10分間撹拌した。撹拌後に得られた溶液を内径4.2cm、高さ30cmの円筒型ガラス容器に満たし、所定時間経過後の、下から20cmの位置の有機相(ポリカーボネート-ポリオルガノシロキサン共重合体を含む塩化メチレン溶液)を採取し、その有機相中の水分量を前記方法により測定した。経過時間ごとの有機相中の残存水分量をプロットすることで経過時間と有機相中の残存水分量との関係式を求め、その関係式から有機相中水分が1.5質量%に到達するまでの時間(分)を求めた。
その後、有機層を全量採取し、遠心機(日立工機(株)製「CF6L」)を用いて3000rpmで5分間遠心分離し、分離した水分を除去して有機相を得た。
実施例7において、PDMS-1に代えてPDMS-2~PDMS-8を用いたこと以外は実施例7と同様にして、共重合体を製造し、洗浄及び油水分離を行い、各工程における有機相中水分が所定値に到達するまでの時間を求めた。結果を表2に示す。
