  • Production and use of plasticizers based on 2,4-isomer of furandicarboxylic acid diesters
    Patent number: 12163008
    Abstract: The present disclosure generally relates to a compound of dialkyl ester of 2,4-furandicarboxylic acid, a method of preparing the compound, a polymer composition comprising a polymer and the compound, a method of preparing the polymer composition, a polymer product comprising the polymer composition and a method of using the compound as a plasticizer in the polymer product. The dialkyl ester of 2,4-furandicarboxylic acid of the present disclosure has greater plasticizing efficiency in a polymer composition that that of the standard phthalate and terephthalate-based plasticizers. The polymer product plasticized with the dialkyl ester of 2,4-furandicarboxylic acid may have improved flexibility, durability, processability and safety as compared to the same polymer product plasticized with conventional phthalate and terephthalate-based plasticizers.
