A parallel plate viscoelastometer for molten polymers /

Soong, Su Syin. January 1983 (has links)
The nonlinear visoelastic behavior that accompanies large transient deformations in high molecular weight polymer melts and concentrated solutions is not at all well-understood, because equipment suitable for the investigation of such phenomena have not been available. This lack of understanding has limited the advancement of plastics processing technology, because the deformations that occur in polymer processing often take the melt well into the nonlinear regime. Furthermore, it has not been possible to test constitutive equations formulated to describe nonlinear phenomena. / A new rheometer, equipped with a specially designed shear stress transducer, has been developed to examine the nonlinear viscoelastic behavior of polymeric liquids. Deformations that can be generated include interrupted shear and large amplitude oscillatory shear. Using the new instrument, a thorough study was made of the rheological behavior of polyisobutylene at 22(DEGREES)C. The results obtained from these experiments were used to evaluate the predictive ability of a constitutive equation recently proposed by Mewis and De Cleyn.
