摘要: Abstract Two mathematical models, Sanchez–Lacombe equation of state and the Perturbed-Chain Statistical Associating Fluid Theory were applied for modelling phase equilibrium poly( l -lactide)–CO 2 d,l -lactide-co-glycolide)–CO systems. Aspen Polymer Plus software was used. The results compared with previously obtained experimental values solubility. solubility scCO in two biodegradable polymers calculated three different temperatures (308, 313 323 K) pressure range (10–30 MPa). characteristic parameters components binary interaction models optimized order to obtain best fit between estimated gas data. suggest that both SL EOS PC-SAFT are reliable describing PLLA–CO PLGA–CO systems at proposed working conditions.
