Webwhy PPG is water soluble (although to a lesser extent than PEG) and PMG is not; PMG does not contain the -OCCO- sequence in the polymer chain. The fact that the polymer-water interactions become less favorable with increasing tempera-ture will also have an impact on the water activity of a solution of PEG. It has been shown by WebNov 16, 2015 · The solubility of benzene in water is 1.79 g/L (about 0.02 mol/L) at 15 °C. So benzene has some solubility in water. But many chemists set the high/low solubility cut-off point at about 0.10 mol/L. By that definition, benzene is insoluble in water. The question then is, "Why is benzene relatively insoluble in water?"
