摘要

The local heat generation that accompanied tensile drawing of polymer films was Successfully observed by infrared diermography as a series of temperature distribution images. These images showed that the high temperature part where rearrangements of molecular orientation and microcrystallities occurred was located mainly at the end of the necked part for the polymers that exhibited necking or appeared uniformly throughout films for the polymers that did not exhibit necking. The generated heat could be roughly estimated, and the relation between the estimated heat and mechanical work led to the thermodynarnic investigation. (c) 2006 Wiley Periodicals, Inc.
