摘要：

A viscosimetric method was used to investigate the molecular association of dextran, 20% and 40% periodate-oxidized dextrans in aqueous solutions. Intrinsic viscosity numbers, [eta], found by Huggins and Kraemer equations, decreased in the presence of denaturing agents like urea, thiourea and guanidinium sulfate. Intrinsic viscosity values also decreased with increasing temperature. This decrease has been even less in the presence of denaturing agents. (C) 1997 Elsevier Science Ltd.
