✦ Synopsis


The pseudoternary phase diagram of the system involving cyclohexane, sodium dodecyl sulphate, propanol, and water was constructed for an SDS-to-propanol mass ratio 1:2. The area of the monophasic microemulsion region was computed. The effects of change of temperature and change of concentration of watersoluble polyacrylamide (PAA) on the microemulsion zone as well as the conductance, viscosity, and adiabatic compressibility of the microemulsion systems were studied. It was observed that for the water system there is a critical temperature below which the microemulsion zone increases with temperature, though at higher temperature the zone decreases within the range studied. The effects of presence of polyacrylamide above and below (0.003 %(\mathrm{w} / \mathrm{v})) also are different from each other. 1993 Academic Press, Inc.

## Abstract The temperature at which polyacrylamide gels are polymerized strongly affects the structure and physical properties of this matrix. The suggested temperature of 0–4 Β°C has been found to produce highly turbid, highly porous and unelastic gels. At temperature of 25 Β°C of higher, the gels
