  • Production and use of polyester carbonates
    Patent number: 6646099
    Abstract: A transesterification process for producing polyester is disclosed. In a first stage of the process there is heated, in an inert gas atmosphere, a first mixture containing at least one dihydroxy compound and at least one diaryl carbonate to form an oligocondensate. In a second stage there is added to the oligocondensate at least one dicarboxylic acid to form a second mixture. The second mixture is heated to a temperature not higher than 290° C. in the presence of a quaternary onium compound as catalyst to form polyester carbonate. Hydroxyaryl formed throughout the process is distilled-off under reduced pressure.

  • Molded article having a rigid support and a rigid hollow member
    Patent number: 6644722
    Abstract: A molded article, e.g., a cross car beam (3), which includes a rigid support (a) having a plurality of perforations, e.g., rigid support (12), and a rigid hollow thermoplastic member (b), e.g., an air duct (15), attached thereto is described. A portion of the thermoplastic material of rigid hollow member (b) extends through at least some of the perforations of rigid support (a), embedding the edges of the perforations therein. The thermoplastic material extending through the perforations forms an attachment element, e.g., an attachment head (24), that serves to fixedly attach rigid hollow member (b) to rigid support (a). Also described is a method of preparing the molded article of the present invention, in which the rigid hollow member (b) is fixedly attached to the rigid support (a) during the blow mold fabrication of rigid hollow member (b).
