AbstractThe synthesis, purification and properties (micellization, rheology) of the following cyclic co- and terpolymers will be discussed. a). Cyclic triblock terpolymer of styrene, isoprene, and methyl methacrylate obtained by end-to-end intramolecular amidation reaction of the corresponding linear a,?-amino acid precursor. b). Cyclic block copolymer of styrene and butadiene formed by intermolecular coupling reaction of the corresponding a,?-dilithium block copolymer with dimethyldichlorosilane and c). Cyclic block copolymer of styrene and isoprene prepared by intramolecular �click� cyclization reaction of linear a-acetylene-?-azido-polystyrene-b-polyisoprene, obtained by using an ?-acetylene protected anionic initiator.
