Description
レイノルズ数=N*(D2/D1)*D1 2*ρ/μ
に基づき、式中、Nはシャフトの回転速度(回転数/秒)であり、D1は内部ケーシングの直径の長さであり、D2は管の直径の長さであり、ρはセメントの密度(kg/m3)であり、μはセメントの粘度(Kg/m.s)である。この式は、バードら著、輸送現象、ウィリー出版、1960年、p.96に説明されているように、当業者に公知であって、参照してここに援用する。
V=F/(π/4*(D1 2−D2 2))
で定義することができ、式中、Vはセメントの上方向の空塔速度であり、Fはセメントの流速(m3/s)であり、D1は反応器のケーシングの内径であり、D2は管の直径である。
従来の連続重合法を用いて、一連のポリマー試料を調製した。具体的には、約25リットルの容量を有する連続撹拌タンク型反応器(CSTR)に、固形分含量約16から約18%で、ヘキサンに溶解させた1,3−ブタジエン単量体およびスチレン単量体を含む重合媒体を投入した。供給した全単量体は、ブタジエンを含めたバランスと共に、約28から約32%のスチレンを含んでいた。また、反応器に、単量体100重量部に対して約0.044から約0.05重量部のn−ブチルリチウムを投入した。
異なる反応配置を採用する以外はサンプル1−12と同様の方法を使用して、一連のポリマー試料を調製した。特に、サンプル1−12で使用した反応器は、「太軸」撹拌装置を備えていた。この撹拌装置は、図5に示したものと同様である。具体的には、内部管は、直径が約15cmであり、幅が約1.3cmのタブを備えていた。その結果、直径約2.5cmの環を有する環状反応器が作り出された。大部分の他の点については、開始剤投入物が単量体100重量部に対して約0.042から約0.057重量部のn−ブチルリチウムを含むものの、重合媒体は同様であった。試料1−12で行ったのと同様の分析を行い、結果を表1に示した。
