Claims (5)
- 1.無水マレイン酸とメチルアルキルビニルエーテルとのエチル又はブチル半エ ステルコポリマーのエタノール溶液を製造するにあたり、(a)溶融無水マレイ ン酸、モル過剰の液状メチルビニルエーテル及びフリーラジカル開始剤を含むア セトン溶液を、約68°〜85℃で、アセトンが予め装■された反応器中に、同 時に供給することにより、溶剤としてのアセトン中でモノマーを共重合し、 (b)エタノール又はブタノールを用いて上記コポリマーのアセトン溶液をエス テル化し、 (c)エタノール蒸気を約85°〜95℃で上記コポリマー溶液中に常圧下で連 続的に注入することにより、上記エステル化溶液中のアセトンをエタノールと溶 剤交換し、その間同時にアセトンを蒸留して留出させることを含む無水マレイン 酸とメチルアルキルビニルエーテルとのエチル又はブチル半エステルコポリマー のエタノール溶液の製造方法。
- 2.上記蒸留の間、溶液が撹拌状態に維持されるように、エタノール蒸気をコポ リマー溶液の表面下に散布する請求項1記載の方法。
- 3.フリーラジカル開始剤が、アルキル若しくはアシルペルオキシド又はペルオ キシエステルである請求項1記載の方法。
- 4.上記エステル化及び溶剤交換工程を、エタノールを用いて同時に実施する請 求項1記載の方法。
- 5.エステル化アルコールがブタノールの場合、溶剤交換をエステル化の次に、 エタノールを用いて実施する請求項1記載の方法。
