This technique can be used to synthesize unique block polymers, such as a block polymer which is comprised of an A block and a B block, wherein the A block is a polymer block which is comprised of a vinyl aromatic monomer and wherein the B block is a polymer block which is comprised of (a) at least one monomer selected from the group consisting of acrylonitrile and methacrylonitrile and (b) a conjugated diolefin monomer, such as 1,3-butadiene or isoprene.
