Abstract
Polymerization of phenylacetylene was carried out with high efficiency in s upercritical or liquid carbon dioxide using rhodium. catalysts. The polymer ization rate in CO2 is higher than in conventional solvents such as THF or hexane. The polymers consist of cis-transoidal and cis-cisoidal species. Th e surface morphology, molecular weight, IR and NMR spectroscopic properties of the resulting polymers are compared to those obtained by polymerization in conventional solvents and discussed in terms of the microstructure of p olymers.
