Co dinuclear catalyst for methyl methacrylate polymerization

Effect of polymerization parameters including cocatalyst concentration, polymerization time, andtemperature on the behavior of a dinuclear α-diimine Co (Ⅱ)-based catalyst was investigated. Therewas an optimum activity at (۶۶.۸۷۵ g (PMMA)/mmol Co. h) [Al]/[Co]= ۱۰۰۰:۱ molar ratio, using amodified methylaluminoxane (MMAO) at ۴۰ °C and ۲ h. Also, spherical polymer particles wasobtained at reaction temperature of ۴۰ °C.
