Abstract

Novel aromatic poly(etheraroylhydrazides), PEHZ, incorporating a methylenic sequence (with number of CH2 units m = 2, 4, 6, 8, 10, 12) in the main chain, have been obtained by solution polycondensation and characterized with several techniques. In particular, Differential Scanning Calorimetry (DSC) and Wide Angle X-ray Scattering (WAXS) gave interesting results. The complex thermal behavior and the lattice parameters of these linear polyhydrazides are a function of the number of methylene units present in the flexible segment. The relationships we found suggest a model: a polymer with disorder in aliphatic segment layers while preserving chain periodicity, that is the classical model of “conformationally disordered crystalline” polymer. © 1999 John Wiley & Sons, Inc.
