Modification of poly(ethylene 2,5-furandicarboxylate) (PEF) with 1, 4-cyclohexanedimethanol: Influence of stereochemistry of 1,4-cyclohexylene units

The tensile strength and elongation at break as well as the O2 and CO2 barrier properties of PECFs were all increased with the content of trans-CHDM. With varied ratio of trans-CHDM/cis-CHDM, the properties of PECFs were tunable.263
