Polymers derived from agricultural sources offer benefits to society of a reduced environmental impact and utilization of an annually renewable resource. Reversible addition fragmentation chain transfer (RAFT) polymerization has been utilized to prepare fully sustainable triblock copolymers. The middle block is fatty acid-derived polyacrylate which is rubbery and amorphous at room temperature. The outer blocks are glassy and semi-crystalline polylactide, which is derived from plant sugars. These triblock copolymers are being investigated for utility as fully sustainable thermoplastic elastomers.
