Polymers containing poly(ethylene glycol) methacrylate and 2-(2-methoxyethoxy)ethyl methacrylate have been synthesized by Cu(0)-mediated radical polymerisation for use as thermoresponsive water-dispersants for carbon nanotubes.
Monodisperse silica-polyaniline core-shell nanoparticles with an average diameter of 26 nm were synthesized by in-situ polymerisation of aniline monomers adsorbed on the silica surface through electrostatic interactions.
Group 4 metal complexes containing phenoxy-amide ligands bearing soft pendant donors are shown to give more highly active ethylene polymerisation catalysts than counterparts containing hard donors or systems without a pendant donor.
The self-assembly and sol-gel polymerisation of novel alkoxysilane-functionalized polymethylsiloxanes provide versatile access to nano-assembled containers, silica-based micro- and nano-architectures and dispersed mixed metal oxide hybrid materials.
In this communication we report, for the first time, the ring-opening polymerisation in the melt of rac-lactide with heterogeneous catalysts. Homogeneous model systems based on silsesquioxanes have been prepared for comparison.
A new amide monomer for step growth polymerisation is reported: the chemistry exploits a bulky malonamide for the synthesis of polyesters and polyamides. No additives are needed and the only by-product, an amine, can be recycled.
Single-barrel scanning electrochemical cell microscopy has been adapted for polymerisation of acrylamide in droplet cells formed at gold electrode surfaces. Localised atom transfer radical enables controlled synthesis and...
Identification of the 1H, 19F, and 13C NMR signals end-groups polytrifluoroethylene synthesized by RAFT polymerisation.
