heal.abstract	Transient bulk creep tests under isothermal conditions at various temperatures were excuted for a cold-setting pure epoxy polymer. The difficulty encountered with transient bulk experiments due to nonlinear variation of free volume with temperature when the specimens were tested in hydrostatic pressure was overcome by applying the linear compressibility method. For this purpose long thin cylinders made of the material were subjected to internal pressure and the elongation of a generator of the cylinder yielded directly the bulk compliance. The bulk compliance composite curve of the substance was formed by applying the principle of reduced variables. It was shown that the bulk compliance presents a rather weak dispersion, which is extended over a broad time range. The transition region of the curve in the time scale was borader than the shear and extension bulk compliance transition regions. An explanation based on the molecular mechanisms of deformation was given for the similarities apparent between shear and bulk viscoelastic behaviour. © 1970 Dr. Dietrich Steinkopff Verlag.	en
