Abstract

Polyacetals are a readily degradable class of polymers with potential uses in the preparation of porous materials and patterned surfaces and in a range of applications as surfactants and drug delivery agents. There are very few synthetic routes to polyglyoxylates in aqueous systems that have been reported in the literature to date, which has limited the further investigation of these materials. The anionic polymerization of sodium glyoxylate in aqueous and organic solutions was investigated in this study. Attempts at polymerizing sodium glyoxylate with sodium hydroxide, sodium methoxide, and methanol/triethylamine were unsuccessful as evidenced by the absence of a polyacetal backbone peak in the proton NMR spectrum. A more likely polymerization method using tartronic acid has been developed to perform the anionic polymerization of ?-carbonyl acids in basic aqueous media. | 43 pages
