As reported in the previous paper (J. Appl. Phys. Japan 27 (1958) 652), ADP longitudinal oscillator has many advantages over quartz when used for measuring complex Young's modulus of high polymers by the composite oscillator method. In the present paper experimental techniques of determining complex rigidity of high polymers by the use of a torsional ADP oscillator are described with some results for polystyrene and polymethyl-methacrylate. In this case, contrary to the case of a longitudinal oscillator, ADP crystal seems to be not always preferable to quartz because of the complicated construction and difficulty in mounting of the oscillator.
