✦ Synopsis

The temperature dependence of the composition of coacervate and equilibrium phases is examined for the polypentapeptide of elastin (~-Val~-~-Pro~-Gly~-~-Val~-Gly~)~ in water. This provides for the development of a phase diagram. CD data is presented that provides information on associated polypeptide structure changes that, when added to previous CD, nmr, and dielectric relaxation data a t lower water composition, allow construction of a phase-structure diagram of the polypentapeptide-water system. The molecular-weight dependence of phase change (coacervation) is included. The volumecomposition studies as a function of temperature also provide temperature coefficients of expansion and of composition important in analyzing the mechanism of elasticity.

The pressure-temperature (P-T) melting curve of lidocaine was determined (dP/dT = 3.56 MPa K(-1)), and the lidocaine-water system was investigated as a function of temperature and pressure. The lidocaine-water system exhibits a monotectic equilibrium at 321 K (ordinary pressure) whose temperature in

Variable temperature Fourier transform infrared (FTIR) spectroscopy was used to study the transition between the micellar and the coagel phases, and between the cubic and the coagel phases, for the hexadecyltrimethylammonium sulfate (CTAS)/water system. The phase transition takes place at 15°C for t
