Brief Communications


The effect of orientation on the acoustic properties of a polyethylene terephthalate film is examined. In a crystallized, uniaxially oriented film the velocity of ultrasound measured along the orientation axis is lower than in an amorphous oriented film, while the velocity of ultrasound measured at angles of over 35° to the direction of orientation rises after crystallization. Evidently the supramolecular organization of the polyethylene terephthalate film before and after heat treatment is quite different.
