  • Publication number: 20220363847
    Abstract: The invention concerns a film based on a binary polymer composition having at least a first polymer and a second polymer. The film is oriented by extruding and stretching the film in at least the machine direction. The glass-transition temperature (Tg) of the first polymer is greater than the orientation temperature and the glass-transition temperature (Tg) of the second polymer is lower than the orientation temperature. Furthermore, a method and use related thereto are described.

  • Patent number: 10301276
    Abstract: According to an example aspect of the present invention, there is provided a method of producing furan carboxylates from aldaric acids in the presence of a solid heterogeneous catalyst and a solvent with short reaction time. The feedstock for the production is a stable compound, which allows industrial scaling of the process. Solid acid catalyst and sustainable solvent provide considerable reduction of toxic waste compared to traditional methods, and recyclability.
