Abstract
An improved apparatus for studying temperature profiles in molten, flowing polymers has been developed. The apparatus incorporates modifications and improvements of earlier temperature profile devices. In addition, this unit made it possible to study temperature profile development as a function of axial flow length. Data taken with the apparatus were found not only to be precise and highly reproducible but also to show the proper trends with respect to physical behavior.
