## Abstract The structural features of poly[bis(4βisopropylphenoxy)phosphazene] (PB(4βip)PP) have been studied by electron microscopy, Xβray diffraction and differential scanning calorimetry techniques. Its orthorhombic lattice constants are determined as follows: __a__ = 3,14 nm, __b__ = 1,14 nm,
The crystal structure and chain conformation of polyibis(3,4-dimethylphenoxy)phosphazene] -PB(dMe)PP -have been studied by X-ray diffraction techniques. The unit cell of this polymer shows an orthorhombic form with the crystallographic parameters a=2.05, b= 1.49, c (chain axis) =0.998 nm. Its space
