Abstract
Described are polyesters comprising (a) a dicarboxylic acid component comprising 2,5-furandicarboxylic acid residues; optionally, aromatic dicarboxylic acid residues and/or modifying aliphatic dicarboxylic acid residues, 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues and ethylene glycol. The polyesters may be manufactured into articles such as fibers, films, bottles, coatings, or sheets.
