Kinetics of Amine-Bis(phenolate) Iron-Mediated ATRP Up to High Pressure
No full textAtom-transfer radical polymerization (ATRP) of styrene catalyzed by chloro-substituted amine-bis(phenolate)iron complexes was investigated via online vis/NIR spectroscopy up to 6000 bar. Pressure significantly increases the rate of ATRP by enhancing both the equilibrium constant, K-ATRP, and the propagation rate coefficient, k(p). The observed negative reaction volume, Delta V-r(K-ATRP), is due to a stronger contraction of the ligand sphere for the Lewis-acidic Fe-III complex compared to the Fe-II complex. Despite the enormous rate enhancement of ATRP, narrow molar mass distributions may be obtained even at very high pressure and thus very high rates

Tacticity Control in the Synthesis of Poly(lactic acid) Polymer Stars with Dipentaerythritol Cores
Full text linkThe synthesis of a family of polymer stars with arms of varied tacticities is discussed. The effect of polymer tacticity on the physical properties of these polymer stars is presented. Dipentaerythritol cores support six poly(lactic acid) (PLA) arms. Lewis acidic tin and aluminum catalysts control the polymerization to afford polymer stars of variable tacticity. The analysis of these polymers by NMR spectroscopy, thermogravimetric analysis, powder X-ray diffraction, and differential scanning calorimetry reveals the effects of tacticity control on the physical properties of the polymer stars. Preliminary decomposition studies suggest that the biodegradation profile of a polymer star may also be tuned by stereochemical control. This is the first systematic altering of tacticity in PLA polymer stars, showing that polymer tacticity can have a great impact on star properties.</p

Data supporting "Iron(II) b-ketiminate complexes as mediators of controlled radical polymerisation" (2016) in Dalton Transactions - EPSRC EP/M000842/1
No full textA series of tridentate, ONO- and ONN-chelating β-ketiminate ligands were synthesised via condensation
reactions, and complexed with iron(II) using [Fe(N(SiMe3)2)2THF]. The complexation reactions proceeded
in high yields to generate novel, monomeric, tetracoordinate iron(II) complexes, each bearing a bis(trimethylsilyl)
amide ligand, as confirmed by X-ray crystallography. These complexes were amenable to
further reaction (protonolysis) with alcohols and phenols, generating alkoxide/phenolate-containing
complexes that were dimeric in the solid state. All complexes synthesised were screened as potential
mediators of the controlled radical polymerisation (CRP) of styrene and methyl methacrylate under both
atom transfer radical polymerisation (ATRP) and organometallic mediated radical polymerisation (OMRP)
conditions. Whilst all of the complexes were relatively poor ATRP mediators under the conditions used here,
regardless of monomer choice, dispersities (Đ) as low as 1.58 for styrene and 1.23 for methyl methacylate
polymerisation under OMRP conditions could be achieved. The better performance in methacrylate polymerisation
suggests the formation of a stronger metal–carbon bond in these systems. In particular, the use
of a β-ketiminate ligand functionalised with an N,N-dimethylethylene pendant arm and a 2,6-diphenylphenolate
ligand affords a potential Fe-based mediator of methyl methacrylate OMRP.Raw data files for X-ray crystallography, NMR spectroscopy and Gel-permeation Chromatography measurements
Controlled radical polymerization of vinyl acetate mediated by a vanadium complex
Full text linkInitiation of the polymerization of vinyl acetate with azobis(isobutyronitrile) in the presence of a vanadium bis(iminopyridine) complex generates vanadium-capped dormant polymer chains with excellent correlation between molecular weight and conversion and good molecular weight distributions.</p
