The use of a new method, inverse GPC, as a tool for the characterization of elastomeric networks, allowed the obtaining of the distribution curves of the network strands. In agreement with previous studies it was shown that photocrosslinked materials exhibit a more homogeneous distribution of the crosslink points than do peroxide cured samples. From the GPC distribution curves, it was possible to calculate M c , the average molecular weight of a network strand.
