Synthesis of oligomers in dense carbon dioxide. The aim of the project is to develop a novel technique for the synthesis of low molecular weight polymers (oligomers) using dense carbon dioxide as a polymerisation solvent. The use of elevated pressure is the major impediment to the commercialisation of such technology. The technique proposed in this project will enable oligomers to be produced at greatly reduced operating pressures and may lead to a more general procedure for conducting other t ....Synthesis of oligomers in dense carbon dioxide.

Linking topology and rheology for designing supramolecular polymer networks. This project aims to develop a foundation for understanding how microscopic topology and intermolecular interactions control the flow behaviour of supramolecular polymer networks. Brownian dynamics algorithms will be developed to unravel the complex dynamics of the network and calibrated by comparison with carefully designed experiments. The expected outcome of the project is a quantitative framework for connecting the ....Linking topology and rheology for designing supramolecular polymer networks. This project aims to develop a foundation for understanding how microscopic topology and intermolecular interactions control the flow behaviour of supramolecular polymer networks. Brownian dynamics algorithms will be developed to unravel the complex dynamics of the network and calibrated by comparison with carefully designed experiments. The expected outcome of the project is a quantitative framework for connecting the molecular structure and energy landscape with resulting macroscopic properties. This project should yield significant benefit in the rational design of supramolecular systems in which the thermorheological properties can be tuned over a wide range of force/time scales with applications spanning from enhanced oil recovery to injectable hydrogels.Read moreRead less
