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.

Abstract: The present disclosure provides a copolyester including a dicarboxylic acid component A comprising a terephthalic acid residue or ester-forming derivative thereof, or a mixture thereof, and a 2,4-furandicarboxylic acid residue or ester-forming derivative thereof, or a mixture thereof, and a diol component B comprising an alkanediol residue having from 2 to 22 carbon atoms, wherein the dicarboxylic acid component A has a total molar content, and wherein the 2,4-furandicarboxylic acid residue or ester-forming derivative thereof, is present in an amount of from 0.1 to 10 mol %, with respect to the total molar content of the dicarboxylic acid component A. Inventive copolyesters have a slower crystallization rate, a higher gas barrier to CO2 and O2 and a higher ratio of 14C to 12C as measured by ASTM D6866 when compared to a comparable copolyester comprising isophthalic acid instead of 2,4-furandicarboxylic acid.
