실험 절차

To a polymerization reactor under high purity nitrogen atmosphere, 10 ml of purified styrene and 20 ml of toluene were introduced and reaction temperature was controlled to 50° C. Ethylene of 4 atm was added to saturate and then 5 ml of methylaluminoxane (2.1 M toluene solution, Akzo Company product) were introduced. 0.44 ml (3.75 mmol of Ti) of toluene solution in which one of the metallocene catalysts is dissolved was added while vigorously agitating. After agitating the reaction mixture for 1 hour, 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/ethylene copolymer. Polymerization results and physical properties of polymers for each catalyst are shown in Table 3.
