실험 절차

Into a dried 4 liter stainless steel-made autoclave were introduced 630 ml of toluene, 1.2 liter of styrene, 24 mmol of triisobutylaluminum and 24 mmol of methylaluminoxane which was prepared in Example at 70° C. with stirring for 30 minutes. To the resultant mixture was added 120 μmol of 1,2,3,4,5-pentamethylcyclopentadienyl titanium trimethoxide to initiate polymerization. After an elapse of 50 minutes, a solution of 260 mmol of maleic anhydride in 360 ml of toluene was added to the mixture to continue polymerization for 60 minutes. After the completion of the reaction, the resultant polymer was taken out from the autoclave, deashed with a mixed solution of hydrochloric acid and methanol, washed with methanol for the purification thereof and dried to afford 570 g of copolymer.
