On the Degrees of Polymerization Obtained in the Overall Polymerization Processes
Kobunshi Kagaku, 1959 ビニル重合における重合度 (P) は重合率の函数として近似的に次のように示される。a) テロゲンとして作用する溶剤を用いた場合 ただし [M] はモノマー, [S] は溶剤濃度, Csは移動定数, xは重合率である。b) 普通の連鎖移動剤として作用する溶剤を用いた場合 (熱重合) ただし, Po, Piはそれぞれ塊状重合および溶液重合 (x=0) の際の重合度である。c) a) にポリマーの連鎖移動を考慮した場合ただしCpolyはポリマーの移動定数である。a), b), c) の式がスチレンー四塩化炭素の熱重合の結果に適応され, 正しいとこを認めた。
