Definitions

  • the present invention relates to PFPA-containing
  • Siloxane oligomer mixtures selected from compounds of the average formula (I). It also relates to mixtures containing at least one PFPA-containing siloxane oligomer mixture according to the invention and at least one natural or synthetic polymer, as well as molded articles containing at least one mixture according to the invention and a slightly polar to non-polar substrate, and also a method for curing the mixtures and the use of these mixtures and the use of the PFPA-containing siloxane oligomer mixtures.
  • the invention relates to mixtures for coating surfaces in order to make them water-repellent or to give them other desired properties typical of silicone, as well as products resulting therefrom.
  • organopolysiloxanes can be applied to solid surfaces, for example textiles, paper and plastics, in order to make the surfaces water-repellent or non-adhesive or to give them lubricity.
  • the organopolysiloxanes most frequently used for this purpose are polymethylsiloxanes or mixtures with methyl hydrogen polysiloxanes.
  • the organopolysiloxanes give the desired surface properties, they often lack sufficient durability. They can be removed, for example, by washing or on contact with organic solvents.
  • Organopolysiloxanes show only limited adhesion to substrates such as, for example, polyolefins, polyethylene terephthalate, polyvinylidene difluoride or polycarbonate, which is due to the slightly polar to non-polar substance nature of the substrates is due. Consequently, a mechanically stable connection with the various materials cannot be achieved by covalent bonding. Adhesion to such materials can currently only be achieved in a complex and multi-stage process through oxygen plasma treatment.
  • EP2151467 already discloses an azido-functional polyorganosiloxane crosslinker of the formula Me 3 Si-O- (Me 2 SiO) 80 - (Me (3-azidopropyl) SiO) 10 -SiMe 3 and ⁇ , ⁇ - (3-azidopropyl) -terminated polydimethylsiloxane with a viscosity of 1000 mPas for crosslinking siloxanes by means of a "click reaction" on Cu catalysts.
  • silanes with functional azido groups which are bonded to the silicon atom via an intermediate link with a carbon chain are already known.
  • azidosilanes Due to their bifunctional character - they have alkoxy groups on the silicon atom and an azide group on an intermediate link - these azidosilanes are suitable as so-called adhesion promoters between organic polymers and inorganic substrates.
  • Applications of azidosilanes and azidosiloxanes for promoting adhesion are known in the literature, but in most cases azide-functionalized monosiloxanes have been described as a reactive primer.
  • azidosilanes serve as intermediate products, since they react by hydrolysis or partial hydrolysis to form the siloxanes according to the invention, which have an azido group at both ends of the molecule.
  • the dimer of N 3 -propyltriethoxysilane N 3 -PTES
  • the siloxanes according to the invention are thermally relatively stable and can enter into covalent bonds via the nitrate intermediate stage, such as to organic polymers.
  • trimethoxysilyl-methylazide 2- (trimethoxysilyl) -ethyl azide, 3- (trimethoxysilyl) -propylazide, 4- (trimethoxysilyl) -butyl azide, 3- (triethoxysilyl) -propylazide and 4- (triethoxysilyl) -butylazide.
  • the azidosilanes are suitable for the production of crosslinkable organic polymers. The azide group binds to the polymer, and the polymer becomes crosslinkable via the hydrolyzable alkoxy groups.
  • PFPA perfluorinated phenyl azides
  • PFPA-NHS N-hydroxysuccinimide-functionalized PFPAs
  • PFPA-Silane N-(2-trimethoxysilylpropyl) -4-azido-2,3,5,6-tetrafluorobenzamide
  • PFPA-Silane The production of “PFPA-Silane” was first disclosed by Bartlett et al. (Adv. Mater. 2001, 13, 1449-1451), in WO03 / 087206 a further method for its production is disclosed.
  • US2010 / 028559 discloses, among other things, the coating of contact lens surfaces with carbohydrate-containing polymers by priming the surface with “PFPA-Silane” ( Figure 1).
  • the "PFPA silane” is applied to silicon substrates such as SiO 2 - Nanoparticles bound and coated with polymers (Example 1, Figure 2).
  • WO98 / 22542 discloses the chemical functionalization of surfaces with perhalogenated phenyl azides, in particular N-hydroxysuccinimide-functionalized PFPAs.
  • PFPA-NHS A method for the preparation of PFPA-NHS (PFPA 1a) is also referred to in J. Org. Chem. 1990, 55, 3640-3647, by Keana et al. referenced.
  • EP2236524 discloses PFPA-based macromolecules in which PFPA-NHS is bound to polyallylamine (PAAm-g-PFPA) or bovine serum albumin (BSA-g-PFPA). These macromolecules are used to coat various substrates.
  • PAAm-g-PFPA polyallylamine
  • BSA-g-PFPA bovine serum albumin
  • the vinyl-terminated polydimethylsiloxane SYLGARD 184 is covalently bound to Teflon® (Tetex from Franz Eckart GmbH) with PAAm-g-PFPA (Example 20).
  • the PAAm-g-PFPA is crosslinked into the polydimethylsiloxane under UV radiation. Good adhesion of the PDMS to Teflon® is achieved.
  • the prior art essentially discloses azide-containing monosiloxanes as adhesion promoters between organic and inorganic materials. In essence, the technologies used to coat hydrocarbon-based substrates use a reactive primer with azide-containing mono- and isolated oligosiloxanes.
  • the known systems of azide-containing polysiloxanes are accessible either by cohydrolysis (of monomers, EP0050768) or by crosslinking (EP2236524) of azide-containing alkoxymonosiloxanes.
  • azide-containing polymers alkyl azides, azidoformates, etc.
  • azidosiloxanes serve as a primer for the later coating;
  • Self-adhesive, crosslinkable silicone compositions for plastics with little polarity to nonpolarity are neither described nor known with this technology. There is therefore still the task of enabling natural or synthetic polymers to adhere to less polar to non-polar substrates, ideally via a self-adhesive, mechanically stable surface coating.
