HCID 62697Benzene, ethenyl-, polymer with 1,3-butadiene

Procedure

5 ml (50 μmol of Ti) of toluene solution in which the metallocene 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.
