The aim of this work was to test two bismuth and one zinc-based catalysts as possible alternatives to organotin compounds for the synthesis of injectable and photocurable esterurethane macromonomers with telechelic methacrylic groups. Additionally, we also switched to a "green" solvent, ethyl acetate (EtOAc), instead of dichloromethane (DCM) used in our previous study. We examined the effect of catalyst concentration on the reaction kinetics and chemical structure of the synthesized macromonomers, as well as on the physico-chemical properties and cytotoxicity of final photocured elastomeric materials.
