Abstract
When amorphous poly(ethylene terephthalate) (I) yarns were annealed for a const. time at different temps., the degree of crystallinity increased with increasing temp. Unoriented samples began to crystallize at >100°; oriented samples crystd. at <100°. The faster crystallizability of oriented amorphous I at <110° showed a greater mol. mobility than that for unoriented amorphous I.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
