Abstract
Instrumentation for time-dependent stress dilatometry of polymers was constructed. Volumetric measurements in creep for polycarbonate and in stress relaxation for polyethylene were carried out. The advantage of the transverse and axial strain rate ratio for volumetric analysis, i n creep, is emphasized. An experimental finding of volume-stress linea rity in stress relaxation measurements is presented and discussed.
