N2  - Molecular weight distributions for block copolymers of polystyrene and   polyisoprene have been determined by gel permeation chromatography for a series of well characterized polymers. Universal calibration curves from [&#951;]M against elution volume and by plots of unperturbed dimensions (ro2)½ against elution volume have been constructed and examined. Normal-probability curves have been used to calculate the heterogeneity ratio MW/MN and the results compared with values from light scattering measurements and from osmometry.
