The volume change ratio of PMMA at 12 MPa has the most significant increment, instead of that at 20 MPa.
- •
Tg of PMMA decreased from 380.5 to 311.4 K withCO2 pressure 0.1–12 MPa, and increased from 311.4 to 323.1 K with 12–22 MPa.
- •
When CO2 pressure is beyond 12 MPa, hydrostatic pressure has a more significant effect on swelling ratio than swelling.
