Resumen

The critical fluctuations of a polymer blend (PVME/d-PS) were investigated by neutron small angle scattering. A mean-field behavior was observed, except in a region very close to the critical temperature where a transition to an Ising-like behavior occurs. The width of this region is T-Tc2.4 K for a mixture with average molecular weights of 89 000 (PVME) and 232 000 (d-PS).
