Abstract
We study early stages of spinodal decomposition (SD) in polymer/liquid crys tal mixtures by solving linearized time-dependent Landau-Ginzburg equations for concentration (conserved order parameter) and orientation (nonconserve d order parameter). We calculate structure factors for concentration and fo r orientation, depending on a quench temperature and concentration. We find a new SD process driven by instability of the orientational order paramete r.
