✦ Synopsis


The unperturbed dimensions of isotactic PMMA have been obtained by the application of various theoretical treatments to laser light scattering measurements carried out in a good solvent (ethyl acetate). A mean value for /M of 7.25.10 -18 cm 2 mol g-~ was obtained. This value is shown to be in good agreement with that obtained from viscosity data in a theta solvent (acetonitrile 0 = 27.5°).
