Entropy Driven Phase Transition in Polymer Gels: Mean Field Theory
We present a mean field model of a gel consisting of P polymers, each of length L and Nz polyfunctional monomers.Each polyfunctional monomer forms z covalent bonds with the 2P bifunctional monomers at the ends of the linear polymers.We find that the entropy dependence ECHINACEA LOZENGES on the number of polyfunctional monomers exhibits an abrupt ch
