  • Publication number: 20140323001
    Abstract: In the present process, reversibly crosslinking composites or storage-stable prepregs are produced by means of a hetero Diels-Alder reactions (HDA,) for example of PMMA polymers. At slightly elevated temperature, these prepregs can be reversibly decrosslinked again by a retro hetero Diels-Alder reaction so that they become moldable. The back-reaction to products which are again crosslinked or high molecular weight then takes place at room temperature.

  • Patent number: 8865053
    Abstract: The present invention relates to a polymer powder which comprises nylon-11, and to the use of this powder for shaping processes, and also to moldings produced from this polymer powder. The shaping processes are layer-by-layer processes which use powders, where regions of the respective layer are selectively melted via introduction of electromagnetic energy. The selectivity may—with no intention of restricting the invention thereto—be achieved via masks, application of inhibitors, of absorbers, or of susceptors, or via focusing of the energy introduced. After cooling, the regions then solidified can be removed in the form of moldings from the powder bed. Compared with moldings composed of conventional powders, the moldings constructed using the inventive powder by one of the inventive processes exhibit marked advantages in terms of component properties, particularly surface finish.
