Procedure

The procedure of Example 7 was repeated with the exception that styrene monomer was used in place of phenyl benzoate to permit the formation of a triblock copolymer of ABA configuration. The materials employed were α-methylstyrene 400 grams; styrene 6.8 grams for formation of the first block. An additional 5 grams of styrene were employed in place of phenyl benzoate; 1,3-butadiene 48 grams; 0.28 millimole secondary butyllithium for impurities, and 0.96 millimole for initiation.
