The synthesis of dimethyl-1,5-naphthalenedicarboxylate and polymers and articles formed therefrom is disclosed, as well as applications for dimethyl-1,5-naphthalenedicarboxylate, its corresponding acid 1,5-NDA, and various synthesis intermediates.

Synthesis and use of dimethyl 1,5-naphthalenedicarboxlyates and intermediates therefrom

Processes for producing aromatic monomers useful for forming polyesters are disclosed. Cost effective steps employed in the processes permit small amounts of process-related materials typically removed from monomer to remain in an aromatic monomer product. In many cases, the presence of the process-related materials left in the monomer product by the cost effective process steps can enhance the performance of the monomer in certain applications. Aromatic monomer products and polymers produced therefrom having these advantages also are disclosed, as well as products such as pasteurizable bottles made from these polymers

Polyester compositions containing terephthalate, 2,6-naphthalate and/or isophthalate moieties, and showing improved properties are disclosed.

Polyester compositions

Method of making high density polyester compositions

A process for preparing condensation polymers comprises forming a dispersion of a reaction mixture in a continuous vapor phase, maintaining the dispersion while passing it through a reaction zone, heating the dispersion in the reaction zone to polymerize reactants in the reaction mixture and form a polycondensate.

Neat and filled polyphthalamide resins are improved in processability when blended with polypropylene and a carboxylated polyolefin resin. Filled polyphthalamides, particularly glass-filled polyphthalamide formulations, are significantly benefited, and glass fiber-filled molding resin formulations of this invention comprising high levels of fiber are more readily moldable than polyphthalamide formulations without the polyolefin components comprising the same and even lower levels of glass-fiber.

Filled polyphthalamide blends having improved processability and

Amorphous polyamide compositions are provided which are transparent and have improved glass transition and thermal decomposition temperatures. The polyamide compositions of the present invention can be prepared as the polymeric condensation product of a diamine component comprising neopentyldiamine, and a diacid component comprising an aromatic dicarboxylic acid.

Melt-processable polyaramide and polyarylate polymers and copolymers are made employing a component containing the 5-t-butylisophthaloyl moiety and aromatic diamines or aromatic diols. The melt processability of these polymers can eliminate expensive processing in making shaped articles. The claimed materials are useful for making fiber, film, laminates, coatings, adhesives and molded objects.

Melt-processable polymeric materials based on 5-t-butylisophthalic

Polyphthalamides which, when filled, have heat deflection temperatures of at least about 240.degree. C. are prepared from compounds of terephthalic acid and isophthalic acid in a ratio of about 70:30 to about 99:1 in combination with a diamine which comprises hexamethylene diamine.
