Polymer theory
WebPSCF is a package of programs for numerically solving the Edwards-Helfand self-consistent field theory (SCFT) to describe spatially inhomogeneous equilibrium structures formed by polymer liquids. The most common use of the package is to treat spatially periodic structures (i.e., periodic ordered phase) formed by molten block polymers or ...

After briefly treating transient network models the reptation approach is introduced. Starting from the basic theory, the various possible molecular mechanisms and their relaxational modes are added, as presented in the various more developed models. Again the emphasis is on linear and
Web1 Theory of Polymer Brushes. The theory of polymer brushes at both planar and curved surfaces is well developed. Only a brief outline of the theoretical discussions is given … Polymers are high molecular mass compounds formed by polymerization of monomers. The simple reactive molecule from which the repeating structural units of a polymer are derived is called a monomer. A polymer can be described in many ways: its degree of polymerisation, molar mass distribution, tacticity, copolymer distribution, the degree of branching, by its end-groups, crosslinks, cry…
