Polyether 618 The sulfonium polyelectrolyte 617 was dissolved in a minimal amount of methanol. The solution was stirred for 1 week under argon, during which pendant polyether 618 precipitated from the solution. The tacky yellow material was completely soluble in CHC13 and THF. Polymer 618 can be dissolved in THF and passed through a 0.2-mm filter for GPC or for use in film casting and device fabrication. Cast films can be completely redissolved into CHC13 or THF. GPC in THF (polystryrene standards) gave A/w = 91,500 and Mn = 33,800.
