Abstract: The generalized intrinsic viscosity-molecular weight equations in the forrn of [n]=kθ[A+(1+AB)M1/2+BM] for polyethylene glycol in tetrahydrofuran and water were deduced by intrinsic viscosity, vapor pressure osmometry and size exclusicn chromatography methods:25℃:[η]=0.126(1+0.004M1/2)(5+M1/2) H2O, 35℃: [η]=0.140(1+0.004M1/2)(3.5+M1/2)

Key words: Polyethylene glycol, Size exclusion chromatography, Intrinsic viscosity equation
