Phosphonium-containing diblock copolymers from living anionic polymerization of 4-diphenylphosphino styrene.
Living anionic polymerization of 4-diphenylphosphino styrene (DPPS) achieved well-defined homopolymers, poly(DPPS-b-S) styrenic block copolymers, and poly(I-b-DPPS) diene-based diblock copolymers with predictable molecular weights and narrow polydispersities. In situ FTIR spectroscopy monitored the anionic polymerization of DPPS and tracked monomer consumption for kinetic analysis. Post-alkylat...
متن کاملBlock Copolymers of Styrene, Isoprene, and Ethylene Synthesis and Characterization Oxide Prepared by Anionic Polymerization. I
Anionic polymerization has been used as a technique for the synthesis of five-block copolymers of polystyrene (PS), polyisoprene (PI), and poly(ethy1ene oxide) (PEO). Two types of such polymers, PEO-PI-PS-PI-PEO and PEO-PS-PI-PS-PEO with varying PEO block length, have been prepared, using potassium naphthalene as the initiator and tetrahydrofuran as the solvent. The polymers were purified by ex...
متن کاملAnionic polymerization of p-(2,2′-diphenylethyl)styrene and applications to graft copolymers
Well-controlled anionic polymerization of an initiator-functionalized monomer, p-(2,2'-diphenylethyl)styrene (DPES), was achieved for the first time. The polymerization was performed in a mixed solvent of cyclohexane and tetrahydrofuran (THF) at 40 °C with n-BuLi as initiator. When the volume ratio of cyclohexane to THF was 20, the anionic polymerization of DPES showed living polymerization cha...
متن کاملEmergence and Stability of Helical Superstructures in ABC Triblock Copolymers
The emergence and stability of superstructured cylindrical phases in frustrated ABC linear triblock copolymers are investigated by the self-consistent field theory. Our results reveal that the complex single/double/triple helices-on-cylinder phases are formed when the straight cylinders-on-cylinder and rings-oncylinder phases are frustrated due to packing constraints. A free energy comparison i...
متن کاملNucleobase-functionalized ABC triblock copolymers: self-assembly of supramolecular architectures.
RAFT polymerization afforded acrylic ABC triblock copolymers with self-complementary nucleobase-functionalized external blocks and a low-Tg soft central block. ABC triblock copolymers self-assembled into well-defined lamellar microphase-separated morphologies for potential applications as thermoplastic elastomers. Complementary hydrogen bonding within the hard phase facilitated self-assembly an...
