Sophisticated macromolecular structures by cationic ring-opening polymerizations

A combination of different types of cationic ring-opening polymerizations (CROPs) has been used to construct macromolecular structures containing polymer segments with different physicochemical properties. The cyclic monomers used are tetrahydrofuran (THF), N-tert-butyl aziridine (TBA), 2-methyl-1,3-oxazoline (MeOX) and 1,3-dioxolane (DXL). The macromolecular structures include different block and graft copolymers, telechelics and macromonomers, star- and comb-shaped polymers, polymer networks and interpenetrating polymer networks (IPNs)
