Following our previous paper on the course of the formation of star-polymers from oligo(oxyethylene)alcoholates as arms precursors and diglycidyl ethers as core building units [1], the nature of polymer alcoholate groups formed in this process has been studied. Primary alcoholate groups reacting with diepoxide or epoxide function in polymer give initially predominantly secondary alcoholate groups...
23Na NMR spectroscopy was used to study complexation of sodium cations (NaClO4) with a few of star-shaped polyethers. The bonding of sodium ions by these polymers having PEO arms and with model compounds has been studied in anhydrous methanol solutions. In this paper the preliminary studies are presented, indicating that star polymers built from PEO arms and core formed from diepoxides, containing...
Following our earlier papers [1–7] on star formation from oligo(oxyethylene)alcoholates as arms precursors and diglycidyl ethers as core the course of reaction of monomethyl ethers of poly(ethylene glycol) (as alcoholate, MPEG-OӨ) and diglycidyl ether of neopentyl glycol (DGNG) has been studied. Epoxy groups (E) react not only with primary alcoholates (p-OӨ), from the starting MPEG, but also with...
