Thermal frontal polymerization using redox components was studied in an attempt to increase the front velocity while decreasing the temperature of the front to produce a self-sustaining front of polymerization in a thinner layer. The cobalt-containing polymer, Intelimer 6050X11, was used in combination with cumene hydroperoxide and a triacrylate. The presence of the Intelimer decreased the front velocity but allowed for thinner layers of polymerization and the production of a composite material with higher filler concentrations. The addition of the reductant, 6-O-palmitoyl-L-ascorbic acid, increased the front velocity in the presence or absence of Intelimer when kaolin clay was the filler material. Interesting nonplanar modes of propagation were also observed in the fronts that contained the cobalt-containing Intelimer.
