Solubility and diffusion coefficient of supercritical-CO2 in polycarbonate and CO2 induced crystallization of polycarbonate

- Solubility and diffusion coefficient of supercritical CO2 in polycarbonate (PC) were measured.
- The dependence of sorption temperature and pressure on the crystallinity of PC was fully investigated.
- The crystallization of PC occurred when T − Tg ≥ 40 °C.
- The crystallization rate increased with the sorption pressure.
- The crystallization rate had a maximum at a certain temperature under a constant pressure.
