Investigation of polymer crystallization kinetics with time dependent light attenuation measurements

J. Fritsch, W. Stille, G. Strobl. Colloid Polym. Sci. 284, 620 (2006)

Abstract

Results obtained for samples of syndiotactic polypropylene and poly(ethylene-co-octene) demonstrate the usefulness of light attenuation measurements in investigations of polymer crystallization. The earlier stages with separated growing spherulites fall in the range of Rayleigh-Debye-Gans scattering. Known relationships describing the dependence of the linear attenuation coefficient on the radius and the index of refraction of a spherulite can be applied in evaluations. The sensitivity of attenuation measurements is much higher than that of conventional tools.
