Local structure of the networks-cross-linking regions

Local structure of the networks-cross-linking regions 

Most physical gels have complex multiple junctions. In Section 7.4, we studied ther-moreversible gelation with junctions of variable multiplicity. In this section, we consider a new method to find the local structure of the networks, i.e., the structure of the network junctions. 

The Eldridge-Ferry method [2] gives the total enthalpy melting A//o of a junction by Anding the slope of Inc against /T through therelaAon 

1 (a) Model of a network junction. The multiplicity k and cross-link length are two fundamental 

Another equation from which the Eldridge-Ferry method starts is the relation between the molecular weight M of a polymer and the gel melting temperature. It is given by
