Supercritical, carbon dioxide in the reaction with the most frequently used tin-organic catalyst of 2-ethylhexanoate was also used by Bratton et al. (67) They have shown that the process occurs in the same mechanism as in conventional solvents, maintaining the linear increase in the average molecular weight with monomer conversion, but with less efficiency.

Supercritical, fluid carbon dioxide is used for SFC. The theoretical aspects of this technique are first investigated with respect to mobile-phase characteristics, optimum linear velocities, and peak capacities. Application of sequential GC and SFC is demonstrated for the analysis of a gasoline/crude ,oil, mixture and a sample of clear nail lacquer.
