Abstract
From the studies on meltviscosities of poly-(chlorotrifluoroethylene) the following relationship was obtained:
logη=-18.70+3.5logM+15.1×103/2.3RT
where η was the melt viscosity determined by parallel plate plastometer, M the molecular weight from the intrinsic viscosity of o-chlorobenzotrifluoride solution, R gas constant, and T absolute temperature. The experiment was carried out in the molecular weight range, 1×105-5×105 and in the temperature range, 500-556°K.
