  • DEGRADABLE POLYMER STRUCTURES FROM CARBON DIOXIDE AND OLEFIN AND CORRESPONDING METHOD
    Publication number: 20250122329
    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.
    Type: Application

  • Degradable polymer structures from carbon dioxide and olefin and corresponding method
    Patent number: 12173116
    Abstract: A method of producing a degradable material comprising steps of hydrogenating 2-ethylidene-6-hepten-5-olide (EVL) by introducing hydrogen to the EVL in order to obtain modified EVL; combining the modified EVL with a catalyst to form a reaction mixture; and subjecting the reaction mixture to reaction conditions that will allow the modified EVL to react by ring-opening polymerization in the presence of the catalyst to form a product composition including polymeric-EVL, wherein the polymeric-EVL is hydrolytically degradable, wherein the reaction conditions include a reaction temperature of from ?40° C. to 70° C.
