The objective of this work is measurements and data accumulation of gas solubility and gas diffusivity as well as development of prediction method and data base of these properties. Outcomes obtained in this work are shown as follows :
1. Solubilities of solute in polymer (vapor-liquid equilibria)
Investigated systems: ethylene + high impact polypropylene, propylene + high impact polypropylene, infinite dilution vapor-liquid equilibrium ratio of hexane in ethylene + high impact polypropylene, infinite dilution vapor-liquid equilibrium ratio of hexane in propylene + high impact polypropylene
The infinite dilution vapor-liquid equilibrium ratios of hexane could be predicted by Sanchez-Lacombe (S-L) equation of state in conjunction with binary interaction parameters obtained from fitting binary phase equilibrium data.
2. Liquid-liquid equilibria for polymer and solvent system
Investigated systems: hexane + polyethylene, ethylene + hexane + polyethylene
Ternary liquid-liquid equilibrium data could be predicted by S-L equation of state with binary interaction parameter.
3. PVT of polymer
Investigated systems: polylactide, poly(butylene succinate), poly(butylenes succinate-co-adipate)
PVT properties of these biodegradable polymer melts could be predicted by group contribute modified cell model equation of state.
4. Data base development for polymer solutions
The data base was developed by using the experimental data described above and literature values. This data base, which plays a part in the thermophysical property data base developed by Dr. T. Baba, National Research Laboratory of Metrology. Japan, will be appeared on the Internet.
