Cationic polymerisation of 6,6-disubstituted pentafulvenes yields highly unsaturated, reactive macromolecules of high mo. lecular weight. The mechanistic pathways leading to the polymers are discussed, and the structure XIV of the polymers has been elucidated by a combination of spectroscopic methods as well as by comparison with model compounds. In contrast to reports in the literature, the ma...

The development of an appropriate model for copolymerisation reactors that can describe the process behaviour over the complete range of conversion contributes to a better understanding of the polymerisation process, helps to avoid unsafe operating conditions and to develop operational and optimizing control strategies. The aim in this work is to study the design and operational issues of a cop...

A series of group 4 amine tris(phenolate) complexes have been prepared and characterised by single crystal X-ray diffraction and multinuclear NMR spectroscopy. It was found that the ligands afforded monomeric titanium complexes and dimeric zirconium structures in the solid-state. The complexes have been tested for the ring-opening polymerisation of rac-lactide under both solution and melt condi...

A weak but significant similarity was found between the prion protein (PrP) and some transcription factors and zinc-finger proteins. A possible interpretation of this similarity is that the PrP is a metal- (copper-) binding transcription factor and might behave like a Zn-finger protein, with the Cu2+ binding to its histidine and serine residues. Copper-binding could create intramolecular bridge...

‘Plug-and-play’ simplified electrochemical atom transfer radical polymerisation of PEGA480 under potentiostatic and galvanostatic conditions proceeds with very good control to conversions up 83%.

Responsive nanogels were synthesised via RAFT-mediated polymerisation-induced thermal self-assembly in cononsolvent mixtures of water and ethanol. The solvent mixture affected the particle size, tacticity properties.
