Our investigation of the vulcanization transition beyond the mean-field level, via both a perturbative renormalization group approach and a diagrammatic analysis of the two- and three-point vertex functions to all orders in perturbation theory, shows that percolation theory correctly captures the critical phenomenology of the vulcanization transition associated with percolative aspects of the liquid and critical states.
