| Popis: | Two polylactide-b-poly(perfluoropropylene oxide) (PLA−PFPO) diblock copolymers were synthesized via a coupling reaction of acid chloride end-functionalized poly(perfluoropropylene oxide) and hydroxy-terminated polylactide. The solubility of these materials in CO2 was measured using a variable-volume high-pressure cell. At a concentration of 1 wt %, the PLA−PFPO copolymers were found to be soluble at modest pressures ( |
