Order in side-chain liquid crystalline diblock copolymers
… that precede a wide array of applications. Using sequential anionic polymerization we synthesized a large number of well-defined SCLCBC's. These materials consist of an amorphous, polystyrene (PS) block and a methacrylate-based, LC block with side-chain mesogens that exhibit the Sc* mesophase. The …

Cobalt Nanoparticle-Macromolecular Complexes and Their Conversion to Oxidatively Stable Entities
… block copolymers were synthesized through the sequential anionic polymerization of styrene and tert-butyldimethylsilyloxystyrene. The silyl ether protecting groups on the second block were hydrolyzed under acidic conditions to afford poly(styrene-b-4-vinylphenol), and the pendent phenols of the …

Synthesis and Self-Assembly of Novel ABC Miktoarm Star Terpolymers
… for such materials was developed, combining anionic polymerization and copper-catalyzed azide-alkyne cycloaddition. At the example of ABC miktoarm star terpolymers and an ABA’ miktoarm star copolymer containing a poly(N-methyl-2-vinypyridinium iodide) (P2VPq) segment, the counterion-mediated …

Synthesis, Characterization, and Properties of Tailored Functional Block Copolymers
… of a specially constructed reactor setup for sequential anionic polymerization that allows parallel block copolymer synthesis based on one identical A-block on a lab scale. For this reason, this setup facilitates the preparation of block copolymer series in a combinatorial fashion. It consists …

Development of Thermoplastic Elastomers with Improved Elastic Properties Based on Semicrystalline Block Copolymers
… triblock copolymers have been synthesized by sequential anionic polymerization of butadiene, isoprene, and ethylene oxide (PB-b-PI-b-PEO) followed by homogeneous catalytic hydrogenation. Anionic polymerization in a one-pot procedure was accomplished by using the phosphazene base t-BuP4, which …

"Smart" Hydrogels based on Trishydrophilic Triblock Terpolymers
… The crucial aspect of this procedure, based on sequential anionic polymerization, was the utilization of the phosphazene base t-BuP4, enabling the anionic polymerization of epoxide monomers in the presence of lithium counterions. It was shown, that ethoxyethyl glycidyl ether polymerizes easily …
