Notizen:
Four polystyrene samples, with molecular weight ranging from 43,300 to 1,112,000 have been irradiated in benzene solution by γ-rays, at four different intensities. Data obtained through intrinsic viscosity and light-scattering measurements on irradiated polymers indicate that, at each intensity, there exists a molecular weight below which any polymer chain is no further degraded. An equilibrium between absorbed and dissipated energy by the macromolecule is supposed, and the equation, MlimI = const. arrived at in a previous study, is verified also by the present experimental results.
