Abstract
Methods are proposed to transform GPG chromatograms into molecular mass distributions /MMD/ using the universal calibration and the intrinsic viscosity of the material measured at GPC circumstances, and in conditions, for which KMHS-constants are known. The results of the calculation are the MMD and the interrelation between the Kuhn-Mark-Houwink-Sakurada constans, K and a for GPC circumstances. It is also shown, that as a simplification a-values available for any condition can be used for the calculation using the experimentally measured intrinsic viscosities in GPC circumstances and within circumstances, for wich KMHS-constants are known.Keywords
