Abstract
In this work two fractions of D-xylan isolated from corn cobs were analyzed by viscometry, using dimethyl sulphoxide and NaOH 4% aqueous solution as s olvent. The polymers presented good stability in the alkaline medium, witho ut indications of hydrolysis during the 15 h of study. A comparative study of the viscometric behavior of the polymers as well the intrinsic viscositi es and the Huggins constants was done, and related to the structure of the polymers.
