N2 - Crystals of highly purified PTS monomer were grown in a light free environment by self nucleation in slowly evaporating saturated acetone solutions at 273K. Low temperatures and the light free environment were chosen to avoid thermal and UV polymerization, respectively, during growth. X-ray polymerization was investigated in a controlled manner by varying the thickness of the aluminum beam filters employed. X-ray topographs were recorded in an intermittent fashion as a function of X-ray dose until reaction was complete. Similarly, UV polymerization was investigated, in situ on the X-ray camera, by recording intermittent exposures whilst the crystal was bathed in UV light in an inert atmosphere. Finally, thermal polymerization was investigated in situ by recording intermittent exposures whilst the crystal was held at a given temperature in a specially designed hot stage.
