Synopsis

This article centers on the depolymerization of dextrans under the action of thennomechanical forces induced by rapid passage of concentrated dextran solutions through capillaries and homogenizing valves. Viscosity measurements combined with theoretical equations related to the properties of the dextran solutions led us to characterize the flexibility of dextrans chains in water. The influences of temperature and pressure gradient through the restrictions on the extent of depolymerization are described. The thermomechanical treatment is particularly effective in the presence of acid catalysts.

Intrinsic viscosity measurements were carried out on dextran samples (of different molecular weights) in aqueous solutions at 25, 28, 31, 34, 37, 40, and 43°C. The extrapolation methods were used for the data; they gave unperturbed dimensions, K 0 , of the chain. The unperturbed root-mean-square end
