When mpc gel is immersed in various water/alcohol mixtures, a change in the gel volumes will be observed depending on not only the composition of the alcohol in the mixture but also in the chemical structure of the alcohol. In water/monohydric alcohol mixtures, the mpc gel will have an irregular swelling behavior with the change of a composition in the alcohol. Showing the so called reentrant volume phase transition. these volume phase transitions strongly depend on the hydrophobic group, the polarity of the alcohol. On the other hand polyhydric alcohol does not affect the swelling of the mpc even when the composition of the alcohol was changed. This suggest that , water molecules hydrated on the poly chains are with drawn by hydration of the alcohol molecules and the volume of the mpc gel is decreased. Therefore is good agreement to the hydration ability of the alcohol and it's polarity.
