AbstractThe polymerization of methyl methacrylate with Ni (II) benzoyl trifluoroacetonate was investigated. The rate of polymerization was proportional to the square root of the initiator concentration and 1.5 power of the monomer concentration. The activation energy for the overall polymerization was 13.4Kcal/mole, which yields 17.6Kcal/molefor the activation energy and 9.58 × 105sec−1for the collision frequency factor for the initiati
