Abstract
AbstractThe retention diagram of polycaprolactone for tert‐butyl acetate was obtained by inverse gas chromatography method in the temperature range of 40‐140 °C. Rate of crystallinity was determined between 45.0 percent and 37.1 percent in the temperatures at 40 and 53 °C, respectively. Thermodynamic interaction parameters were determined for cyclopentane, cyclohexane, tetrahydrofuran and 1,4‐dioxane with polycaprolactone between 70 and 130 °C. Specific retention volumes, Vgo, Flory Huggins polymer‐solvent interaction parameters, χ12∞, equation of state polymer‐solvent interaction parameters, χ12*, weight fraction activity coefficients of the solvents at infinite dilution, Ω1∞, effective exchange energy parameters, X̄12were determined.
