Phase separation in solid poly(styrene-stat-methyl methacrylate) copol
ymers (styrene volume fractions 0.1-0.9) was investigated by polarized
Rayleigh-Brillouin and Rayleigh light scattering methods. Both these
methods showed evidence of microphase separation caused by chemical po
lydispersity of the copolymers. (C) 1998 Elsevier Science Ltd. All rig
