Group transfer polymerization of biobased monomers

► Vinylic group of tiglic acid esters is not polymerizable by GTP. ► Tiglic acid attached to a methacrylate backbone can be polymerized by GTP. ► Vinylic group of itaconic acid esters is not polymerizable by GTP. ► Itaconic acid esters can be used to end-functionalize living GTP polymers. ► Fumaric and maleic acid esters can be used to end-functionalize GTP polymers.
