•New AB-type monomers for the Passerini multicomponent reaction are introduced.•Polyesters with varous side chains are prepared via multicpomponent reactions.•Oxditaion of sulfur within these polymers (to polysulfones) led to improved thermal properties.
An efficient way to synthesize an AB-type monomer, bearing a carboxylic acid and an aldehyde moiety, for Passerini step-growth polymerizations is described. This monomer was directly polymerized in a polyaddition approach applying the Passerini three-component reaction. Using various isocyanides for this polymerization resulted in polyesters with different amide side chains. Another structural feature of these polymers is a sulfur containing backbone, which is due to the monomer synthesis via thiol-ene chemistry. Oxidation of these polymers resulted in polysulfones exhibiting tunable thermal properties.
