Abstract

Polymer processing flows involve a strong coupling of mechanical and thermal effects that have a significant impact on the final properties of the material. Simple molecular arguments suggest that Fourier's law must be generalized to allow for a tensorial thermal conductivity in polymers subjected to deformation. In our laboratory we have developed a novel, optical method to obtain quantitative measurements of anisotropic thermal diffusivity in polymers subjected to deformations. In this paper we report measurements of anisotropic thermal diffusivity and stress in both molten and solid polymers in uniaxial extension. These data are used to test the stress- thermal rule.
