Process for the determination of the visco-elastic characteristics of polymers and arrangement to carry out the process

Abstract

A process for the determination of the visco-elastic characteristics of polymers which includes stimulating a rolling pendulum which is supported on a flat horizontal surface of a polymer sample, to free, attenuated rolling oscillations at different tempertures of the polymeric sample and measuring the attenuation and/or material frequency of the rolling oscillations in dependence on the temperature of the polymeric sample. An apparatus for carrying out such process which includes a table for the accommodation of the sample, which has a flat surface, means for heating or cooling of the table top to certain temperatures, means for adjustment of the table, whereby the flat surface of the polymeric sample is positioned in the a horizontal position, a rolling pendulum that is supported by the surface of the polymeric sample, and means for the reading of the oscillations of the rolling pendulum.
