  • Patent number: 12091783
    Abstract: Stretched filaments based on aromatic polyethers, wherein the filaments have been stretched at a temperature between glass transition temperature and melting point and wherein the filaments are cooled down to below the glass transition temperature under full tensile load and a process for production thereof and use thereof.
    Type: Grant
    Filed: October 17, 2019
    Date of Patent: September 17, 2024

  • Patent number: 11807025
    Abstract: A plastic material is useful as an ink receiver or printing medium in dye diffusion thermal transfer printing, wherein the plastic material has a polyamide component (a), and a (co)-polyamide (b) based on ether units and amide units. This plastic material can be used to make a layered structure. The layered structure can be used in dye diffusion thermal transfer printing. A security and/or valuable document with the layered structure can be obtained. Based on the finding that the (co)-polyamide (h) offers sufficient absorbency for the printing ink, the layer produced from the plastic material can be printed on by means of dye diffusion thermal transfer printing with a good color intensity.

  • Patent number: 8007916
    Abstract: A composite part is produced by a process in which at least one of components a) and b) of said composite part is treated with an Openair plasma on a contact surface between said components a) and b) prior to production of the composite part, followed by molding-on of the other component; wherein said components are as follows: a) a part which entirely or to some extent comprises a molding composition comprising at least 40% by weight of a polyamide whose monomer units contain an average of at least 8 carbon atoms, and b) a part comprising another molding composition.

  • Publication number: 20080217821
    Abstract: Two shaped articles A and B which are not directly weldable to one another can be welded to one another with the aid of a film C if the material of the first surface of this film is compatible with the material of the shaped article A and the material of the second surface of this film is compatible with the material of the shaped article B and if either the film C or a surface region in contact therewith absorbs electromagnetic radiation. The welding is carried out by brining the first surface of the film C into contact with the shaped article A and the second surface of the film C into contact with the shaped article B and inputting electromagnetic radiation.
