Well-defined PE-b-PTFE diblock copolymers via combination of coordination chain transfer polymerization and condensation reaction: Facile preparation and surface modification of polyethylene film
In this paper, a series of well-defined polyethylene-b-polytetrafluoroethylene diblock copolymers (PE–b– PTFEs) were prepared by a coupling reaction of hydroxyl-terminated polyethylene (PE–OH) and isocyanateterminated 1H,1H-perfluoro-1-tetradecanol (PFDO–NCO). PE–OH was prepared by the coordination chain transfer polymerization using 2,6-bis[1-(2,6-diisopropylphenyl)imino ethyl] pyridine iron (...
متن کاملThe limits of precision monomer placement in chain growth polymerization
Precise control over the location of monomers in a polymer chain has been described as the 'Holy Grail' of polymer synthesis. Controlled chain growth polymerization techniques have brought this goal closer, allowing the preparation of multiblock copolymers with ordered sequences of functional monomers. Such structures have promising applications ranging from medicine to materials engineering. H...
متن کاملSynthesis of well-defined conjugated copolymers by RAFT polymerization using cysteine and glutathione-based chain transfer agents.
Novel cysteine and glutathione-based chain transfer agents were synthesized and successfully applied to the straightforward synthesis of well-defined conjugates via a RAFT process.
متن کاملSynthesis of well-defined epoxy-functional spherical nanoparticles by RAFT aqueous emulsion polymerization†
The environmentally-friendly synthesis of epoxy-functional spherical nanoparticles has been achieved using polymerization-induced self-assembly (PISA) in aqueous solution. Firstly, a non-ionic hydrophilic stabilizer block, poly(glycerol monomethacrylate) (PGMA), was prepared by reversible addition–fragmentation chain transfer (RAFT) solution polymerization in ethanol. This water-soluble precurs...
متن کاملRapid Synthesis of Well-Defined Polyacrylamide by Aqueous Cu(0)- Mediated Reversible-Deactivation Radical Polymerization
Atom transfer radical polymerization (ATRP) of acrylamide (AM) has proved challenging, typically exhibiting low conversions and broad molecular weight distributions (MWDs). Herein, we report the synthesis of well-defined polyacrylamide (both homo and block copolymers) via aqueous copper(0)mediated reversible-deactivation radical polymerization (Cu(0)RDRP), exploiting the in situ disproportionat...
