Synthesis of new α, α′, β-trisubstituted β-lactones as monomers for hydrolyzable polyesters

Abstract: Abstract-Novel ®,® 0 ,¯-trisubstituted¯-lactones have been prepared by a concise and ef cient synthesis in ve steps from commercial racemic diethyl oxalpropionate. These lactones with different lateral groups can be polymerized or co-polymerized for obtaining polyesters with high molecular weight. Chemical modi cation of these functionalized hydrolyzable polymers will be used to adjust their properties to the selected temporary applications.

“…In addition, the size exclusion chromatography (SEC) analysis gave a molecular weight value close to the theoretical value and the molecular weight distribution was close to unity. With all of these positive results, it is now possible to conclude that the anionic polymerization allows an excellent control of the molecular weight of polymers [81]. Thirdly, further study was carried out on the block copolymer.…”

“…SEC results had shown an increase of molecular weight between the intermediate block and the final diblock polymer. Several copolymerizations were performed to confirm that the anionic polymerization of these new lactones had a living character [81]. From these very satisfactory results, all searches are now made with polyesters derived PDMMLA.…”
