Özet

Specific retention volume, V-g(0) of benzene, ethyl benzene, n-propyl benzene, isopropyl benzene and chlorobenzene on poly(4-methyl-1-pentene) were obtained by inverse gas chromatography at temperature range in degrees C of 240 and 280. The Flory-Huggins polymer-solvent interaction parameters were determined. The solubility parameter of poly(4-methyl-1pentene), delta(2) was determined as 7.64 (cal/cm(3))(1/2) at room temperature by extrapolation of the values obtained at high temperature. Then, dielectric constant and dipole moment of poly(4-methyl-1-pentene) were calculated by means of solubility parameter determined experimentally. The data found in this study are in agreement compared with the ones obtained in the literature.
