Abstract: An error analysis was made to evaluate the method of estimating number average molecular weight of polymer samples from the intrinsic viscosity and GPC chromatogram[2]. The evaluation was made according to a mcdel chrematogram of normal distribution and the result was in good agreement with that obtained from the real polymer samples.

Key words: GPC, intrinsic viscosity, number average molecular weight, polymer
