Investigation & Optimization of Parameters Affecting LTM Catalyst Activity in EMMA Copolymerization Using Box-Behnken Design

In the present study, according to the Box-Behnken Design three operational factors including [Al]/[Ni], the amount of MMA, and reaction time, in three levels were considered to optimize the late transitional metal catalyst activity which has been applied in copolymerization of ethylene and methyl methacrylate. Under the optimum conditions ([Al]/[Ni], 700; MMA, 25 mL; copolymerization time, 20 h) catalyst activity was approximately 2081 kgpol/molNi. To study the factors efficacy, per se, and their interdependent interaction effects on catalyst activity, contour and surface plots were investigated
