実験手順
In a 1000-ml three-necked round-bottomed flask equipped with stirrer, thermometer, and dry nitrogen sweep were placed methyl acrylate (x g), styrene 100-x g, tetrahydrofuran (400 ml), and azobisisobutyronitrile (1 g). The stirred solution was heated at reflux for 24 hours. The cooled solution (100 ml portion) was slowly poured into methanol (400 ml) being agitated in a blender. The resulting white precipitate was collected on a Buchner funnel, sucked dry, slurried with fresh methanol (to remove styrene), and vacuum-dried at 50°C. The amounts of monomers used and polymer molecular weight were as follows:
