Abstract

We study transitions to periodic structures in block copolymers melts, including concentration fluctuations self-consistently in the analysis. Phase diagrams are constructed for diblock and triblock copolymers of finite molecular weight. The concentration fluctuations increase the stability of the isotropic state, and induce a shift in k *, the wave vector of maximum scattered intensity, to lower values as the transition is approached. We calculate the shift in k * near the transition, and obtain the anisotropic scattering function in the ordered state.
