The evaluation of crystalline and non-crystalline orientation factors of PVA film from the data on x-ray diffraction, infrared dichroism, and birefringence is performed, and the following conclusion are obtained:<br>(1) By using experimental result of the infrared dichroism and x-ray diffraction analyses, infrared transition moment angle of a crystalline absorption band can be determined quantitatively The crystalline orientation factor of a uniaxially stretched PVA can be determined quantitatively from infrared dichroism measurements. The transition moment angles Θj, to the crystalline chain axis for the 1141cm-1 band are 81°25′ and 83°25′ for samples annealed at 160°C and 90°C, respectively.<br>(2) The non-crystalline orientation factor com be determined from infrared dichroism of the uniaxially stretched PVA films dyed with Congo Red, by compensating method using non-dyed films The infrared dichroic orientation factor Fam, (I. R) for the 755cm-1 band is in agreement with the non-crystalline orientation factor Fam, (Bir) calculated by assuming that the additivity of birefringence is valid.
