title: Massive internal fracture of an amorphous polyester.
abstract: When amorphious polyethylene terephthalate is subjected to a tensile load of 2 to 4 x 10(8) dynes per square centimeter wthin the approximate temperature range 40 degrees to 70 degrees C, an unusual optical effect occurs. The transparent polymer film is suddenly transformed into a brilliantly reflecting strip with the luster of silver. Extensive formation of voids accounts for the unorthodox behavior.
