실험 절차

To a 100 ml-flask in a glove box, (C5Me4SiMe3) Sc(CH2SiMe3)2 (THF) (10 mg, 21 μmol) and [Ph3C][B(C6F5)4](19 mg, 21 μmol) were added, and toluene (30 ml) was further added. To the obtained solution a mixture of styrene (2.148 g, 21 mmol) and isoprene (1.431 g, 21 mmol) was added, and the whole was subjected to a polymerization reaction at 25° C. After 12 hours, methanol was added to stop the polymerization reaction. The reaction mixture was poured into methanol (200 ml) to precipitate a polymer. The precipitated polymer was filtrated, and dried at 60° C. under reduced pressure, to thereby obtain 1.64 g of isoprene-styrene copolymer.
