ABSTRACT:
An expeditious method has been found for measuring the concentration of particles found in a polymer composition such as in wire and cable jackets. This procedure involves dissolving the polymer composition in a suitable solvent so that the particles form a dispersion in the solvent. The concentration of these particles in the solvent is then measured through transmission spectroscopy and this value is related to the concentration of the particles present in the original polymer body.
