Latest Patents

Renate Wilms holds a patent for the "Production and use of polyester carbonates." This patent describes a transesterification process for producing polyester. In the first stage of the process, a mixture containing at least one dihydroxy compound and at least one diaryl carbonate is heated in an inert gas atmosphere to form an oligocondensate. In the second stage, at least one dicarboxylic acid is added to the oligocondensate to create a second mixture. This mixture is then heated to a temperature not exceeding 290°C in the presence of a quaternary onium compound as a catalyst to form polyester carbonate. Hydroxyaryl formed during the process is distilled off under reduced pressure.
