Patent number: 10385244Abstract: The present invention comprises a single-component binder for heat-sealing applications which can be used for the sealing of polyester foils, in particular of polyethylene terephthalate foils (PET foils) with respect to containers made of polystyrene, of PVC, and of polyester. These polyesters can in particular be polyethylene terephthalate (PET) or polylactic acid (PLA). The binders here feature not only good seal seam strengths but also in particular good transparency and excellent application properties. A substantive aspect of the invention is that the sealing can be achieved without addition of adhesion promoters, in particular without addition of adhesion promoters based on polyvinyl chloride (PVC) or on polyester, and that barrier properties and sealing properties achieved in respect of containers made of PS and of PET are nevertheless at least comparable with, and sometimes better than, those achieved with heat-sealing systems already marketed.Type: GrantFiled: May 7, 2015Date of Patent: August 20, 2019Assignee: Evonik Roehm GmbHInventors: Andre Hennig, Thomas Arnold, Michael Wicke, Juergen Hartmann, Bruno Keller, Guenter Schmitt, Michael Waldhaus

Patent number: 10071510Abstract: The invention relates to a process for producing storage-stable polyurethane prepregs and to moldings (composite components) produced therefrom. The prepregs and, respectively, components are produced by mixing (meth)acrylate monomers, (meth)acrylate polymers, hydroxy-functionalized (meth)acrylate monomers and/or hydroxy-functionalized (meth)acrylate polymers with uretdione materials. Photoinitiators can also optionally be added. This mixture or solution is applied by known processes to fiber material, e.g. carbon fibers, glass fibers or polymer fibers, and is polymerized with the aid of radiation or of plasma methods. Polymerization, e.g. at room temperature or at up to 80° C., gives thermoplastics or thermoplastic prepregs, and these can subsequently also be subjected to forming processes. The hydroxy-functionalized (meth)acrylate constituents can then be crosslinked with the uretdiones already present within the system, by use of elevated temperature.Type: GrantFiled: February 26, 2014Date of Patent: September 11, 2018Assignee: EVONIK DEGUSSA GmbHInventors: Emmanouil Spyrou, Guenter Schmitt, Friedrich Georg Schmidt, Sandra Reemers, Birte Olland, Michael Spittler, Holger Loesch

Publication number: 20130323993Abstract: The invention relates to a process for producing polyurethane prepregs which are stable during storage, and to mouldings (composite components) produced therefrom. The prepregs or components are produced by mixing (meth)acrylate monomers, (meth)acrylate polymers, hydroxy-functionalized (meth)acrylate monomers and/or hydroxy-functionalized (meth)acrylate polymers with uretdione materials and moreover with aromatic amines which accelerate a free-radical polymerization reaction. This mixture or solution is applied by known processes to fibre material, e.g. carbon fibres, glass fibres or polymer fibres, and is polymerized at room temperature or higher temperatures with the aid of initiators, e.g. dibenzoyl peroxide. Instead of amine acceleration and subsequent hardening with initiators, it is also possible to use other known room-temperature curing systems, e.g. permaleate systems. Polymerization, e.g. at room temperature or at up to 80° C.Type: ApplicationFiled: December 1, 2011Publication date: December 5, 2013Applicant: Evonik Degussa GmbHInventors: Guenter Schmitt, Sandra Reemers, Emmanouil Spyrou, Heike Heeb, Stephan Kohlstruk, Friedrich Georg Schmidt, Elke Gollan
