    Polymer blends are formulated by mixing polymers with different chemical structures to create new materials with properties intermediate between those of the individual components. While FloryHuggins (FH) theory explains some basic trends in blend miscibility, the theory completely neglects the...

    We introduce a spin field theory for many self- and mutually avoiding polymers with arbitrary stiffness on a regular lattice. The model allows for the complete crossover between flexible polymers and rods. The model also includes arbitrary polymer length distributions and arbitrary volume...
