| Research Abstract |
Phase behavior of polymer aqueous solutions was found not to be so simple as usually considered. The cloud point in aqueous poly(N-isopropylacrylamide) (PNIPA) solutions is shown to be governed not only by the hydrogen bonds between PNIPA and surrounding water molecules but also by the end group and primarystructure of PNIPA chains. It is concluded that the cloud-point curve does not directly correspond to the bimodal as far as aqueous PNIPA solutions are concerned.
