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, ethylene glycol residues, and 1,4-cyclohexanedimethanol residues. The polyesters may be manufactured into articles such as fibers, films, bottles, coatings, or sheets.
Claims26
A polyester composition comprising at least one polyester which comprises:
- (a) a dicarboxylic acid component comprising:
- i) 70 to 100 mole % of furandicarboxylic acid residues;
- ii) 0 to 30 mole % of aromatic dicarboxylic acid residues having up to 20 carbon atoms;
- and
- iii) 0 to 30 mole % of aliphatic dicarboxylic acid residues having up to 16 carbon atoms;
- and
- (b) a glycol component comprising:
- i) 1 to 99 mole % of 1,4-cyclohexanedimethanol residues;
- and
- ii) 1 to 99 mole % of residues of ethylene glycol,
- wherein the total mole % of the dicarboxylic acid component is 100 mole %, and the total mole % of the glycol component is 100 mole %.
