Abstract
N-Succinyl-chitosan (1) was depolymerized with 7.5 M aqueous HCl at room temperature or 3.3 M aqueous HCl at 40°C and the molecular weights (MW) of the products were determined by size-exclusion chromatography-multi angle light scattering (SEC-MALS) and their viscometric features were investigated. The intrinsic viscosity ([η]) obtained at the concentration of 0.1-0.3% (w/v) in saline showed a linear relationship between log[η] and logMW, which provided the coefficients in the Mark-Houwink equation.
