Abstract Pole figure analysis has been applied to different types of poly(vinyl chloride) (PVC) samples. Drawn samples of formulations containing increasing amounts of plasticizer show that the presence of plasticizer at concentrations exceeding 20 pph decreases the orientation of the crystalline phase for a given draw ratio. Cast and pressed films of PVC show incipient orientation in the plane of the films. This orientation can be removed to a great extent by immersing the films in diethyl ether. The method is experimentally feasible and the resolution achieved is determined by the automation of the equipment.
