A Thermostatic Chamber for the Measurement of Light Scattering from Solids at Elevated Temperatures

Abstract
A chamber is described which, in conjunction with a Zimm type light scattering apparatus, may be used to determine the angular dependency of the scattering from polymer films at temperatures between 30°C and 200°C at scattering angles between 10° and 70° from the incident beam. The temperature is maintained by circulating heated air. The use of this chamber is illustrated with a series of measurements of scattering from a polythene film.
