Query: Two Simple Approaches to Sol-Gel Transition   We represent a theory of polymer gelation as an analogue of liquid-glass
transition in which elastic fields of stress and strain shear components appear
spontaneously as a consequence of the cross-linking of macromolecules. This
circumstance is explained on the basis of obvious combinatoric arguments as
well as a synergetic Lorenz system, where the strain acts as an order
parameter, a conjugate field is reduced to the elastic stress, and the number
of cross-links is a control parameter. Both the combinatoric and synergetic
approaches show that an anomalous slow dependence of the shear modulus on the
number of cross-links is obtained.
