3D-ising and Lifshitz critical behavior in a mixture of a polymer blend and a corresponding diblock copolymer

Thermal composition fluctuations and the associated crossover from the 3D-Ising to the isotropic Lifshitz universality class have been studied in a three-component mixture made of a critical polymer blend and the corresponding diblock copolymer. The rather complex phase diagram and the critical exponents of the isotropic Lifshitz universality class will be presented. (C) 2000 Elsevier Science B.V. All rights reserved
