This research entails solution polymerization in a supercritical fluid          (SCF) as solvent.  The thesis is that the advantage of polymerization           in SCF is that polymer (product) solubility can be easily controlled by         varying the temperature and pressure.  This, in turn, implies that              polymer of a desired narrow molecular weight (MW) range can be produced         because as soon as this MW is attained, the temperature or pressure are         changed, and all the monomer and polymer are instantaneously                    precipitated out of solution.  The reaction thus comes to an immediate          halt.  There is an added advantage in that the SCF remains a gas and            the expensive, highly energy-intensive process of separating product            from solvent is eliminated.
