We propose a class of thermodynamically admissible models for complex fluids, based on a tensor and a scalar as configurational variables. These models are developed within the GENERIC framework of nonequilibrium thermodynamics, which introduces a number of important restrictions. For clarifying the symmetry properties of friction matrices, we introduce the concepts of bare and dressed Onsager-Casimir symmetry. It is shown that nonisothermal generalizations of many successful models are contained in the proposed class, such as the Doi-Ohta model for emulsions and blends or the pompon model for melts of branched polymers. for LaTeX users @article{HC\"Ottinger2002-48, author = {H.
