Correlations between the sol fraction and concentration of elastically active network chains

Relations between the concentration of elastically active network chains in the gel, v_eg, and the weight fraction of the gel, w_g′ have been examined in crosslinked systems obtained by stepwise alternating polyaddition of a mixture of a tri- and bi-functional monomer bearing one kind of functional groups to a bifunctional monomer bearing another kind of groups. A reduction factor has been found bringing the dependence between log v_eg and w_g almost to a single curve independent of the parameters characterising the initial composition of the system and conversion of the functional groups.
