概要

論文の詳細を見る
In order to supplement the dynamical investigation of the secondary absorption region of polymethyl methacrylate, which appeared at 20℃ in 1/2 cps vibration measurement as described in the previous report, the torsional creep was observed at various temperatures from -50℃ to 30℃. Assuming that this polymer is "thermorheologically simple", the master dreep curve was constructed, and the activation energy of 30 kcal/mol was obtained.
