The shortcomings of the phantom network concepts have stimulated a number of attempts to find theoretically a more satisfactory elastic free energy function to describe the properties of elastomers at different states of deformation. The efforts to explain the real network behaviour by a special non-topological mechanism can be divided into four types. The first group considered intra- and intermolecular effects los-ni) wjtii these assumptions it is hard to explain values of the Mooney-Rivlin parameter which are of the order of the corresponding Cj parameter. 

The term "topological mechanism" refers to intramolecular changes of bond lengths and/or angles without breaking of bonds or formation of new bonds.
