Thermoplastic polymer compositions having enhanced properties, as well as methods of making and using the same, are provided. Thermoplastic polymers according to some aspects of the present invention may be rigid, but may also be suitable for use in applications requiring a thermoplastic polymer resin. Thermoplastic polymers according to various aspects of the present invention may be useful in preparing shaped articles such as, for example, sheets, films, tubes, preforms, bottles, profiles, and other similar articles.

Isocyanate-modified rigid thermoplastic polymer compositions

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 and 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues. The polyesters may be manufactured into articles such as fibers, films, bottles, coatings, or sheets.

Polyester compositions containing furandicarboxylic acid or an ester thereof, and 2,2,4,4-tetramethyl-1,3-cyclobutanediol

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.

Polyester compositions containing furandicarboxylic acid or an ester thereof, cyclobutanediol and ethylene glycol

Disclosed is an oxidation process to produce a crude carboxylic acid product carboxylic acid product. The process comprises oxidizing a feed stream comprising at least one oxidizable compound to generate a crude carboxylic acid slurry comprising furan-2,5-dicarboxylic acid (FDCA) and compositions thereof. Also disclosed is a process to produce a dry purified carboxylic acid product by utilizing various purification methods on the crude carboxylic acid.

Oxidation process to produce a crude and/or purified carboxylic acid product

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

Polyester compositions containing furandicarboxylic acid or an ester thereof and cyclohexanedimethanol

Polyester compositions composed of (a) titanium-catalyzed polyesters containing the residues of terephthalic acid, cyclohexanedimethanol, and ethylene glycol; and (b) at least one chelating phosphorus species and/or reaction products thereof, represented by the structure: The polyester compositions are characterized by having superior color and/or clarity.
