Description
a)ラジカル重合の禁止剤溶液を、不活性の加圧ガスと一緒に、少なくとも1つの導管(供給管)を介してモノマー含有容器に入れる工程であって、当該導管は、上昇領域を含み、かつ当該導管の端部で容器中に禁止剤溶液を導入するための及びガスを吹き込むための手段を有し、並びに
b)容器の中身と禁止剤溶液を、導管にガスを吹き込むことによって混合する工程
を含み、ここで、工程(a)において、加圧ガスの流速を、禁止剤溶液の流動様式として栓流又は環状流が導管の上昇領域中で生じるように調節し、かつ工程(b)において、容器中のガス空塔速度を≧0.1mm/sに調節する、ラジカル重合可能なモノマーの再安定化法によって解決される。
(a)禁止剤溶液に届く採取管を有する禁止剤溶液のための槽(Kessel)、
(b)ガス供給管を介して禁止剤溶液のための槽と連結されている少なくとも1つの加圧ガス貯蔵容器、
(c)加圧ガス貯蔵容器に備わった減圧手段、
(d)ガス供給管におけるガス空塔速度の調節手段及び
(e)モノマー容器に通じる導管への採取管の接続手段
を含む、供給ユニットの形態で提供される。
導管中に存在するすべての禁止剤溶液がタンクに確実に輸送されるように、加圧ガスの流速は、禁止剤溶液の流動様式として栓流又は環状流が、殊に導管の上昇部で生じるように調節される。栓流又は環状流の形成は、なかでも加圧ガスの流速及び導管直径に依存する。好ましくは、加圧ガスの流速は、6〜12m/s、殊に8〜12m/sの範囲にある。流速の突き止め方は当業者に知られている。例えば、それはA.E.Dukler及びY.Taitel著のMultiphase Science and Technology,第1章,第1頁〜第94頁に記載の方法に従って行われることができる。
