The dynamic polarization of protons in polystyrene was observed in a wide range of temperature to investigate the contribution of the electronic spin-spin interactions. The results are compared with a theory based on the rate equations. An important role of the electronic spin-spin interactions is clarified; the solid effect is dominant at room temperature, but it is quenched strongly by the spectral diffusion and the nuclear polarization is induced by the cross relaxation of the electronic spins at low temperature.
