The present invention relates to a continuous method of preparing a block-graft or star-shaped copolymer. This method involves providing a living polymer, mixing the living polymer with a first monomer under conditions effective to produce a block copolymer, wherein the first monomer includes a polymerization site and a polymerization initiation site, and mixing the block copolymer with a second monomer under conditions effective to produce a block-graft or star-shaped copolymer. The present invention also relates to a continuous method of preparing a graft or graft-block copolymer. This method involves mixing a first monomer and a second monomer under conditions effective to produce a copolymer of the first and second monomers, wherein the second monomer comprises a polymerization site and a polymerization initiation site, mixing the copolymer with a third monomer under conditions effective to produce a graft copolymer, and mixing the graft copolymer with a fourth monomer under conditions effective to produce a graft-block copolymer. The present invention also relates to graft, graft-block, block-graft, and star-shaped copolymers produced by the methods of the present invention.
