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.

Abstract: A unitized frame housing a slidable door. The main body of the frame is a single molded structure fittable between a pair of walls within a building. Guide means provided within the main body slidably receives a door which is opened and closed by an electric motor. Various linkages and gears connect the electric motor to the door. A neck integrally attached to the main body extends outwardly of the building walls housing the main body of the frame forms a passageway allowing access through the building walls and main body when the door is not closed. The neck flares outwardly providing a trim portion which seats outwardly of the building walls facilitating a smooth boundary between the building and neck. Means are provided for securing the unitized main body to the building.
