Abstract: A film of poly(trimethylene arylate) and a polystyrene wherein the polystyrene concentration is in the range of 0.5 to 40 weight %. Poly(trimethylene terephthalate) and polystyrene are particularly useful. Also, disclosed are processes for preparing the film.

Abstract: A composition of poly(trimethylene arylate), especially poly(trimethylene terephthalate), and polystyrene that is useful in the production of shaped articles such as fibers, films, and molded structures. The invention is useful as a masterbatch, also known as a concentrate, composition for combining with a PTT diluent in the economical production of fiber spinning compositions.

Abstract: A concentrate of poly(trimethylene arylate), particularly poly(trimethylene terephthalate) and polystyrene containing 15 to 40 wt % polystyrene is employed in the production of shaped articles such as films, pellets, and fibers. In one embodiment the concentrate is melt mixed with a polymeric diluent comprising a poly(trimethylene arylate) to form a spin blend comprising 0.5 to 1.5 wt % polystyrene, and the spin blend is extruded through a spinneret comprising a plurality of identical orficies, producing a plurality of filaments.

Abstract: This invention relates to a process for producing non-whitening molded articles of poly(trimethylene terephthalate) (PTT) with reduced whitening by treating the articles with heat.

Abstract: Disclosed is a thermoplastic molded vehicle light bezel including a polyester molding resin comprising a thermoplastic polyester selected from the group consisting of poly(butylene terephthalate) homopolymer, poly(butylene terephthalate) copolymer, poly(trimethylene terephthalate) homopolymer, poly(trimethylene terephthalate) copolymer and blends thereof, and sodium montanate.

Abstract: A process for making a high viscosity poly(trimethylene terephthalate) (PTT) resin having a low cyclic dimer content of less than or equal to 1.1 wt % as determined with nuclear magnetic resonance analysis and an intrinsic viscosity in the range of 0.9 to 2.0 dL/g; the PTT resin composition provided by the process; and molded articles derived from the composition are disclosed.

Abstract: Disclosed is a thermoplastic molded article having at least one surface having a metal layer, wherein the article includes a poly(trimethylene terephthalate) molding resin having a cyclic dimer content of less than or equal to 1.1 wt %, as determined with nuclear magnetic resonance analysis, based on the weight of said poly(trimethylene terephthalate) repeat units and said cyclic dimer; and an intrinsic viscosity of 0.9 to about 2.0 dL/g. Preferably the metal layer is aluminum. Molded parts include vehicle light bezels including headlight, taillight, direction light bezels, and vehicle interior light bezels.
