Abstract
Studies of molecular weight heterogeneity have been carried out on various celluloses, both before and after exposure to the degradative effect of ultraviolet radiation. Fractionation was carried out on the nitrate derivatives of the samples studied. The data show that significant changes have taken place in the molecular weight distribution patterns of the degraded celluloses.
