摘要：

The influence of stirring rate on the suspension copolymerization of methyl methacrylate-styrene system was studied. A significant growth of particle size during the copolymerization reaction takes place. It was found that the increase of stirring rate produces a reduction of particle size, being possible to relate the final average particle size to the stirring rate. The kinetic of copolymerization reaction corresponds to that of bulk free radical initiated polymerization and it is not affected by the stirring rate. Copolymerization composition and average molecular weight distribution are in reasonable agreement with the data reported in the literature for the same monomer systems in bulk polymerization. This copolymer shows enhanced thermal stability compared to methyl methacrylate polymers.
