Polymer materials comprising coupled components
View Patent ↗Disclosed are intermediate products (semifinished products) for polymer materials, comprising surface-modified components, said polymer materials based on the intermediate products, a method for producing the intermediate products, and the use thereof.
1. A method for producing intermediates for polymeric materials with filler components of organic or inorganic components comprising the steps of:
distributing a free radical initiator on a surface of the filler component, adding a thermoplastic polymer and crosslinking is initiated by energetic impact via ionizing radiation to result in cross-linked polymer-chains to the surface of the filler component.
2. The method according to claim 1 , wherein the free radical initiator in solution or as finely divided suspension or dispersion is distributed on the filler component and/or dissolved in a solvent and distributed on the filler component.
3. The method of claim 1 , wherein the filler component is present in a finely divided state.
4. The method according to claim 1 , wherein the filler components are surface-modified, and are mineral filler components, wherein the mineral filler components are present with an average grain size in the range of 5 nm to 250 microns.
5. The method according to claim 1 , wherein the thermoplastic polymer is added in solution to cover the filler component with the free radical initiator.
6. The method according to claim 1 , wherein the filler components are surface-modified and/or unmodified filler components, wherein the thermoplastic polymer is used as a solution or is used as a suspension or is used as a dispersion or in the form of a finely divided powder covering the surface of the filler component.
7. The method according to claim 1 , wherein the filler components are optionally surface-modified mineral/inorganic filler, wherein a coupling agent and the free radical initiator are used in a molar ratio 100:1 to 1:100.
8. The method according to claim 1 , wherein the filler components are surface-modified mineral filler components, wherein the mineral filler component is covered with a coupling agent that is a bifunctional silane or a functional polysiloxane, and then the free radical initiator is distributed on this surface.
9. The method of claim 1 , wherein the filler component is optionally surface-modified mineral filler component, and is covered with the free radical initiator, and thermoplastic polymer, wherein the coupling is initiated with ionizing radiation or with electron beams or with a mixture of electron beams, X-rays and ultraviolet radiation.
10. The method of claim 1 , wherein the filler component is covered with free radical initiator and thermoplastic polymer, wherein the coupling is initiated with ionizing radiation like electron beams, UV radiation or X-rays.
11. The method of claim 1 , wherein the thermoplastic polymer is oligomeric, prepolymeric or macromolecular.
