The Torsional Quartz Crystal Method for Viscoelastic Measurements of Dilute Polymer Solutions

概要

論文の詳細を見る
Mason's torsional crystal method was improved for measuring the viscoelasticity of dilute polymer solutions. Resonant periods and conductances of the torsional crystals in liquids were measured by means of a universal electronic counter with a period multiplier unit up to 10^5 periods and a phase-sensitive detector, respectively. Three quartz crystals, one of which had a polished surface, were used to calibrate the constants of the crystals in Newtonian liquids at the frequencies of the fundamental and the third harmonic at a temperature of 30.0℃. Complex intrinsic rigidities of monodisperse poly-α-methyl styrenes in cyclohexane solutions were measured at 39.0℃.
