The second stage polymerization would stop when all the styrene monomer in
the reaction solution was consumed, as the residual alpha- methylstyrene would
then be below the ceiling concentration at the polymerization temperature . H
Thus ...

For example, thermoplastic elastomeric compositions of poly(styrene-b-diene-b-
styrene) with high 1,4-polydiene microstructure can be prepared by sequential
monomer addition using an alkyllithium 7 9 initiator in hydrocarbon media. ' One
