| Research Abstract |
Solubilities of dyestuffs like as anthraquinone with OH, NH2, and CH3 groups in supercritical CO2 were measured at the temperature from 353 to 383 K and the pressure ranges of 10 to 15 MPa. The experimental results were correlated accurately by an equation of state as a function of temperature and pressure. Moreover the IGC apparatus was newly developed for the measurements of the polymer glass transition temperature. The pressure depression of glass transition temperature of polyacrylic acids were correlated successfully in terms of average molecular weight of the polymer.
