Effect of ionic liquids on the RAFT polymerization of butyl methacrylate

In Situ Monitoring of Polymerization-Induced Self-Assembly and Gelation During the Synthesis of Triblock Copolymers via Time-Resolved Small-Angle X-ray Scattering and Rheology

“…The dispersity index of molecular weight ( M w / M n ) was 1.3 [as determined by size-exclusion chromatography (SEC)] in the final state at all the c values studied herein (Figure S3). The obtained dispersity index is somewhat high for RAFT polymerization; this may be attributed to the fact that the apparent reaction rate in radical polymerization of methacrylate monomers in [BMIM]­[PF 6 ] is more than 10 times faster than that in conventional solvents . Nevertheless, all CTAs are found to participate in the polymerization as indicated by NMR.…”

The NMR signals from CTA, observed from 2.7 to 2.4 ppm, rapidly diminished or shifted just after the start of the polymerization (Figure S2b).…”

Bioionic Liquids: Enabling a Paradigm Shift Toward Advanced and Smart Biomedical Applications

“…While they have been used as solvents and plasticizers, BILs and ILs have also been grafted onto the structures of a vast assortment of polymers to enhance biocompatibility. [28,122] These blends and grafted polymers often create aggregates and selfassemble formations that can be adapted to drug delivery systems. [122] For example, cellulose-poly(L-lactide) grafts synthesized in imidazolium-based ILs were self-assembled into micelles and used for sustained drug release.…”

“…These assemblies had cores and shells as hydrophobic PLA and hydrophilic cellulose segments, respectively. [122,123] Similar imidazolium IL-polyacrylamidebased aggregated structures have been used for thermal and pH stimulus-responsive drug delivery. [124,125] ILs protonating groups like N,N-dimethylaminoethyl groups gave rise to the decontraction of the brush structure, reduced micellar diameter, and induced rupture of the micelle at a higher pH, thus making it a viable structure for pH-sensitive drug delivery.…”
