Abstract
Preliminary x-ray studies were carried out on the wholly para-oriented aromatic polyamide-hydrazide fiber based on p-aminobenzhydrazide and terephthaloyl chloride. Clearly evident from a quantitative study of the meridional scattering are many orders of a large repeat length (29.69 Å, or a multiple thereof) giving the diffraction pattern a “collagen-like” appearance. An orthorhombic unit cell with a = 8.5 Å, b = 4.9 Å, and c = 29.69 Å (chain axis repeat) fits the available x-ray data. With two molecules per unit cell, the calculated density is 1.51 g/cm3.Keywords
