“…The DSC measurements were carried out in the temperature range from -50 "C to 150 "C at a heating or cooling rate of 5 "C/min in an N, purge. The XRD works were conducted by the same method as reported earlier 14) using a heating device in the temperature range from -50°C to 150°C. 1216, 680 (s, P=N), 1 165, 1020, 952 (s, P-0-C).…”

The structural features of poly[bis(4-isopropylphenoxy)phosphazene] (PB(4-ip)PP) have been studied by electron microscopy, X-ray diffraction and differential scanning calorimetry techniques. Its orthorhombic lattice constants are determined as follows: a = 3,14 nm, b = 1,14 nm, c = 0,992 nm. The space group of this polymer is suggested to be P 2,212, -02, and the molecular conformation of the chains possibly to be (trans3cis)2. This polymer exhibits a crystal/crystal transition at 86 "C below its T(1) transition (120°C). The thermal behavior is similar to the characteristics of poly[bis@-methoxyphenoxy)phosphazene].
