The scattering of light from thin polymer films. I. Experimental procedure

Abstract The measurement of the scattering of light by solid polymers is a means for studying their structure. Films are the most convenient form for working with highly scattering polymers, which are subjected to such treatment as temperature variation, mechanical deformation, and orientation. In measuring scattering from films, it is necessary to correct the observed scattered intensity for ( a ) refraction at film interfaces, ( b ) reflection, and ( c ) secondary scattering. The necessary correction factors are described in this paper. The application of these correction factors is illustrated in the case of scattering by a polyethylene film.
