摘要
The polymerization of methyl acrylate (MA) with Nd(naph) 3 Al( i Bu) 3 α,α′ dipyridyl catalyst was studied. The molecular weight and its distribution were determined by gel penetration chromatography. Kinetic studies show that the MA polymerization rate is the first order with respect to monomer concentration. The apparent activation energy of MA polymerization is 49 34 kJ·mol -1 .
