特開平3-220211号公報の実施例に記載された方法と同様にしてフラッシュ乾燥された環状オレフィンランダム共重合体を得た。すなわち、以下のような方法で環状オレフィンランダム共重合体を得た。
VO(OC2H5)Cl2をシクロヘキサンで希釈し、バナジウム濃度が6.7ミリモル/L-シクロヘキサンであるバナジウム触媒を調製した。
エチルアルミニウムセスキクロリド(Al(C2H5)1.5Cl1.5)をシクロヘキサンで希釈し、アルミニウム濃度が107ミリモル/L-ヘキサンである有機アルミニウム化合物触媒を調製した。
重合器より抜出した、環状オレフィン系ランダム共重合体溶液を、配管に送り込み、前混合を行ない、ボイラー水およびpH調節剤として、濃度が25重量%のNaOH溶液をこの混合溶液に添加し、前記した重合反応を停止させ、また、共重合体中に残存する触媒残渣をこの混合溶液中から除去(脱灰)した。この脱灰された混合溶液を、フラッシュ乾燥工程に入る前に一旦、有効容積1.0m3の撹拌槽を用いて1時間混合した。
二重管式フラッシュ乾燥器(外管径2B、内管径3/4B、長さ27m)とフラッシュホッパー(容積200L)とを用いて、上記したような加熱工程を経た混合溶液から重合溶媒とともに大半の未反応テトラシクロドデセンを除去した。二重管式フラッシュ乾燥器の加熱源として、2.5MPa(25kg/cm2G)の水蒸気を用いた。このようにして、樹脂Aを得た。樹脂Aの極限粘度は0.50dl/g、TMAは143℃であった。測定条件は以下のとおりである。
135℃でアトランティック型粘度計を用い、極限粘度を測定した。

製造例1で得られた樹脂Aをシクロヘキサンに溶解し、濃度15重量%に調製した。その溶液300gにラニーニッケル触媒(ニッケル含有量40重量%)1.3gを加え、水素分圧3MPa、温度100℃で4時間反応した。触媒を濾過した後、反応液をアセトン中に加えて、重合体を析出させ、ろ過・乾燥により樹脂Bを得た。樹脂Bの水素添加率はほぼ100%、極限粘度は0.5dl/g、TMAは143℃であった。
