WebPoly[oligo(ethylene oxide)] based gradient and random copolymers with diﬀerent co mpositions are synthesized via Cu-based atom transfer radical polymerization. The solubility behavior of these copolymers in pure water and in the presence of diﬀerent salts, surfactants and ethanol is investigated. According to WebThe chain-length dependence of the location of the solubility gap is mainly determined by the combinatorial entropy of the chains. The water solubility of PEO, which is unique in this respect among the polyethers, can be explained in terms of a good strutural fit between the water and the polymer. highbrow cleveland tn

"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?" " - Solubility of ethylene oxide in water
