摘要/Abstract

摘要： The solubility of styrene from polystyrene in supercritical carbon dioxide is measured at 323 K, 333 K, and 343 K in the
pressure range from 12 to 28 MPa. Based on the association concept and the theory of dense gas sorption in polymers, a
displacement and association mechanism on supercritical fluid extraction of the monomer from the polymer is proposed. And, a
novel mathematical model for correlating the solubility data obtained from the experiments is also proposed in the paper.
