摘要： A method for preparing tapered block copolymers in a polymerization process by charging an initiator and monomers sequentially with one or more charges of first one of the monomers, then with a mixture of the two monomers, and then with one or more charges of the second monomer alternating with one or more charges of the first monomer with subsequent coupling to produce a polymodal tapered block copolymer. Suitable monomers include conjugated dienes and monovinylaromatic compounds.
