Organic Thiols

Dibutyl itaconate, a bio-sourced monomer, is melt-condensed with various aliphatic diols to generate unsaturated polyesters carrying exo-chain double bonds; these exo-chain double bonds readily undergo Micheal addition with a variety of organic thiols and amines, including some derviatized amino acids, like cysteine and proline.
