Abstract:
Experimental molecular weight distribution curves are presented for two degraded cellulosic materials. Both samples were degraded to approximately the same average degree of polymerization, the first by the normal viscose-aging process and the other by acid-catalyzed hydrolysis. Comparison of these curves reveals a fundamental dif ference in the distribution of chain lengths in these two degraded materials.
