Abstract

Polycondensation of poly(p-oxybenzoyl) in solution was studied to establish the relation between the morphology of crystals and the reaction conditions. Poly(p-oxybenzoyl) whiskers can be formed by using liquid paraffin or Therm S 800 as a solvent. The observed density (1. 50-1. 51 g/cm**3) of obtained whiskers is close to density (1. 52 g/cm**3) calculated from the X-ray data. The whiskers gave sharp peaks in the X-ray diffraction patterns, higher crystal-crystal transition temperatures in the differential scanning calorimetry and higher thermal decomposition temperatures in the thermal gravimetry. These facts suggest that the obtained needle crystals can be termed polymer whiskers.
