Abstract:

As an alternative to using statistical mechanical calculation of the free energy of a network, one may go directly to the dynamics of the molecules and derive the dynamical constitutive equation. This has several advantages. 1 There does not need to be separation of microscopic and macroscopic behaviour i. e. one can avoid the calculation of a free energy and the subsequent assumption that this free energy can be employed in Naviers equations. In polymer problems this separation is not valid. 2 Transport coefficients have a structure for networks, and this cannot be obtained from static statistical mechanics. 3 The permanent constraints of the network invalidate conventional Gibbs formula and need difficult generalizations such as the replica method. A dynamical approach avoids this. Keywords Polymers.
