Versuchsvorschrift

To a polymerization reactor under high purity nitrogen atmosphere, 50 ml of purified styrene and 50 ml of 1,3-butadiene were introduced and reaction temperature was controlled to 25° C. Then, 5 ml of triisobutylaluminum (1,0 M toluene solution) and 5 ml of methylaluminoxane (2.1 M toluene solution, Akzo Company product) were sequentially introduced. 5 ml (50 μmol of Ti) of toluene solution in which the metallocene catalyst is dissolved was added while vigorously agitating. After agitating for 2 hours, 10 wt % of chloric acid-ethanol solution was added to terminate a reaction the reactant was filtered, washed with ethanol and dried in a vacuum oven of 50° C. to obtain a final styrene/1,3-butadiene copolymer. Polymerization results and physical properties of polymers for each catalyst are shown in Table 5.
