Gyorgy, Csilla published the artcileSynthesis and derivatization of epoxy-functional sterically-stabilized diblock copolymer spheres in non-polar media: does the spatial location of the epoxy groups matter, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is epoxy functionalized sterically stabilized diblock copolymer sphere synthesis.
Epoxy-functional sterically-stabilized diblock copolymer spherical nanoparticles were synthesized via polymerization-induced self-assembly (PISA) in mineral oil. Epoxy groups were located either (i) in the nanoparticle cores or (ii) within the steric stabilizer chains. For the first system, RAFT dispersion polymerization of glycidyl methacrylate (GlyMA) was conducted using a poly(lauryl methacrylate) (PLMA63) precursor. The second system involved statistical copolymerization of GlyMA with lauryl methacrylate to produce a P(LMA50-stat-GlyMA9) precursor followed by chain extension using Me methacrylate (MMA). 1H NMR studies and THF GPC anal. indicated that high monomer conversions (â?95%) and narrow mol. weight distributions (Mw/Mn â?1.17) were obtained for both formulations. Dynamic light scattering indicated hydrodynamic diameters of 26 nm and 28 nm for P(LMA50-stat-GlyMA9)-PMMA67 and PLMA63-PGlyMA89 spheres, resp. Transmission electron microscopy studies confirmed a well-defined spherical morphol. in each case. Post-polymerization modification of these spherical nanoparticles was examined by reacting the epoxy groups with benzylamine. For the PLMA63-PGlyMA89 spheres, an [amine]/[epoxy] molar ratio of unity was sufficient to react all the epoxy groups. In contrast, the P(LMA50-stat-GlyMA9)-PMMA67 spheres required a fifty-fold excess of benzylamine for complete reaction. Furthermore, epoxy ring-opening reactions were conducted using either a trace amount of water or 50% volume/volume aqueous acetic acid at 110°C.
