To investigate the mechanical anisotropy in oriented nylon 12, the direction of the hydrogen bond in the a-c plane of the α form was determined by wide-angle X-ray diffraction measurements under various pressures. The hydrogen bond of the a form is nearly parallel to the rolled plane, unlike in the γ form. The mechanical properties of unoriented and doubly-oriented samples were investigated by viscoelastic measurements. In all doubly-oriented samples, the temperature dependence of the storage moduli at 0° and 90° to the chain direction in the rolled plane exhibited a cross-over, which is interpreted in terms of the manner of connection between crystalline and amorphous regions. The storage modulus of the α-form sample in the 90° direction was higher than that of the γ form because of the difference in the direction of the hydrogen bond.
