Carbon dioxide is an attractive solvent for a variety of chemical processes because it is inexpensive, non-toxic, and non-flammable. Solvent separate is simple because C02 reverts to the gaseous state upon depressurisation. For a few selected processes, liquid or supercritical C02 (S0002) is alrea used as a solvent on a significant industrial scale, e.g., decaffeination of coffee, precipitation polymerisation of tetrafluoroethylene and copolymers, dry- cleaning (MiCell). A number of other applications are being tested at the pilot scale. Nonetheless, there are two key issues that have hindered the industrial implementation of C02 and that will limit future growth of this technology if unresolved, i.e., (1) the relatively high pressures needed to achie reasonable solvent densities with C02; (2) the fact that C02 is a very poor solvent for most common non-fluorinated hydrocarbon polymers. Chea C02-soluble hydrocarbon polymers may be the enabling technology for applications such as precision cleaning of microelectronics, dispersi polymerisation, coatings, microlithography and biotechnology (e.g., inexpensive surfactants for solubilisation of biomolecules). For these reasons, propose to develop hydrocarbon polymers based on vinyl monomers that are substantially soluble (>5% w/v) in C02 at low temperatures (25C) and low pressures (55-70 bar). We propose to develop high-throughput (HTP) methodologies for all stages of the investigation (i.e., synthesis, characterisatic and phase behaviour measurement).
