Abstract:  The initial rate of heat evolution for methyl methacrylate polymerization (v0) is decreased by adding poly(methyl methacrylate) into the polymerization system. The effect of poly(methyl methacrylate) on the value of v0 is a function of concentration and relative molecular mass of poly(methyl methacrylate). The addition of polymer does not significantly influence the maximum rate of polymerization, but shortens the time needed to reach it as well as the overall time period of polymerization. In the presence of solvent cyclohexanone the value of v0 is not affected by poly(methyl methacrylate) addition.
