1. A composition comprising:
a. a transesterified furan-based polyester comprising first-alkylene furandicarboxylate repeat units (R1F) and one or more of a second-alkylene furandicarboxylate repeat unit (R2F), a first-alkylene terephthalate repeat unit (R1T), and a second-alkylene terephthalate repeat unit (R2T); and b. a transesterified terephthalate-based polyester comprising second-alkylene terephthalate repeat unit (R2T) and one or more of a first-alkylene terephthalate repeat unit (R1T), a second-alkylene furan repeat unit (R2F), and a first-alkylene furandicarboxylate repeat units (R1F); wherein the first-alkylene group (R1) and the second-alkylene group (R2) are independently selected from a C2 to C12 aliphatic group, and wherein the composition has an NMR blockiness index of greater than 0.00 and less than 1.00. |
