The invention includes a composition comprising a vinyl sulfone monomer, a thiol monomer and an acrylate monomer. In one embodiment, the thiol monomer reacts with the vinyl sulfone monomer preferentially over the acrylate monomer, and this differential selectivity allows for the control of the architecture of crosslinking polymer network. The invention further includes a composition comprising an electrophilic monomer, a nucleophilic monomer, a nucleophilic catalyst and an acid, wherein the concentrations of the nucleophilic catalyst and acid are selected as to provide a specific induction time for the polymerization reaction of the composition.
