  • DEGRADABLE POLYMER STRUCTURES FROM CARBON DIOXIDE AND OLEFIN AND CORRESPONDING METHOD
    Publication number: 20220073675
    Abstract: A method of producing a degradable material includes steps of providing ?-valerolactone 2-ethylidene-6-hepten-5-olide (EVL) or other suitable monomer; combining the EVL or other suitable monomer with a catalyst to form a reaction mixture; and subjecting the reaction mixture to conditions that will allow the EVL or other suitable monomer to react in the presence of the catalyst to thereby form a product composition including a polymer of the EVL or other suitable monomer, where the polymer is hydrolytically degradable.
