The respective flow times, τ0 and t, were measured at 25°C for the solvent and polymer solutions, with relative viscosities ηr = t/τ0. The extrapolation to zero concentration was made by using both the Huggins and Kraemer equations (Cantor and Schimmel 1980; Tsvetkov 1989) and the average values were considered as the value of intrinsic viscosity.","tracks":[]}
