Establishment of equilibrium after temperature changes of aqueous solutions of star-shaped eightarm poly(2-isopropyl-2-oxazoline) with calixarene in the core was studied using light scattering. The times to establish equilibrium teq in the solution were determined as functions of temperature and concentration. It was found that teq increased several times (up to 10) compared with teq at low temperatures as the turbidity temperature was approached. It was shown that teq increased with increasing solution concentration.
