A model was developed to aid in the selection of healing monomers that can rapidly dissolve catalysts in self-healing materials. Predictions are made regarding dissolution rates of Grubbs' catalyst in a small library of ring-opening metathesis polymerization (ROMP)-active norbornenyl-based healing monomers. The Grubbs' catalyst and the healing monomers were experimentally assigned sets of Hansen parameters, and it was observed that healing monomers and blends of monomers with parameters similar to the catalyst were able to rapidly dissolve the catalyst. The model is limited in its ability to predict dissolution trends of healing monomers with substantially different viscosities.
