Definitions
- the invention relates to thermoplastic polyurethane, in particular fibers, cable sheathings and hoses, in particular compressed air hoses containing the reaction product of an isocyanate (a) with a compound (i) which contains at least one, preferably an isocyanate-reactive group, preferably secondary amine. and at least two, preferably two, silicon-organic groups.
- the invention relates to thermoplastic polyurethane containing silicium-organic groups, wherein in each case at least two, preferably two silicon organic groups are connected via a urea group with the thermoplastic polyurethane.
- the invention relates to thermoplastic polyurethane containing the reaction product of an isocyanate (a) with a compound (i) which is preferably at least one isocyanate-reactive group, in particular hydroxyl group and / or primary and / or secondary amino group has a secondary amino group, and at least two, preferably two silicon-organic groups.

Silicon-organic group-containing thermoplastic polyurethane and thus obtainable ver ⁇ wettable TPU, in particular fibers, Lucasummantellungen and hoses, insbeson dere compressed air hoses and the corresponding, via the silicon-organic groups, in particular siloxane crosslinked products.
- Thermoplastics are plastics that remain thermoplastic when repeatedly heated and cooled in the temperature range typical of the material for processing and application.
- the term "thermoplastic” is understood to mean the property of a plastic in a temperature range which is typical for it to soften in the heat and to harden on cooling and, in the softened state, to be repeatedly shaped by flow as a molded part, extrudate or forming part into semi-finished products or articles.
- Thermoplastics are widely used in the art and are in the form of fibers, sheets, films, moldings, bottles, jackets, packages, etc.
- Thermoplastic polyurethane (hereinafter referred to as TPU) is an elastomer which finds use in many applications , eg shoe applications, foils, fibers, ski boots, hoses.
- TPU Thermoplastic polyurethane
- the advantage which results in the case of the TPU by the possibility of thermoplastic processability, however, is at the same time a disadvantage of these materials in view of the lower heat distortion resistance compared with crosslinked polymers. It would therefore be desirable to combine the advantages of thermoplastic processing with those of excellent heat distortion resistance of crosslinked polymers.
- thermoplastic polyurethane with a silane
- the silane is coupled to the polyurethane by means of a crosslinking agent.
- hydrolysis of the silane crosslinking of the originally thermoplastic polyurethane is subsequently achieved, eg after shaping.
- a disadvantage of this technical teaching is that a number of individual steps are required to obtain the crosslinked TPU.
- two reactions are required, first with the crosslinker and then with the silane.
- the use of the crosslinker which binds the silane to the TPU is required since direct use of the silane should lead to degradation of the TPU.
- the object of the present invention was to develop thermoplastic polyurethane, in particular fibers based on thermoplastic polyurethane, containing silicon organic groups which are accessible via a simple, rapid and inexpensive preparation process, have excellent crosslinking properties and, in particular, in the Use as fibers have a very good level of properties in the crosslinked state.
- thermoplastic polyurethanes described at the outset are novel thermoplastic polyurethanes described at the outset.
- Silane-organic compounds are to be understood as meaning the term “silane” used in this specification Accordingly, the term “modified with silane” is to be understood as meaning that the corresponding substance has been modified with a silicon-organic compound.
- the compound with which the silane is introduced into the TPU is incorporated directly into the polyurethane.
- it is not indirectly, via a cross-link, attached to the TPU, but the silane is present in the TPU structure itself.
- silanes or "silicon-organic groups” or “silane groups” are in this document compounds, in particular generally known alkoxysilanes, for example di- or tri-methoxy- and / or ethoxysilanes, which preferably contain the following general structural unit:
- R is an alkyl radical or aryl radical which may optionally be heteroatom-substituted, preferably an alkyl radical having 1 to 10, preferably 1 to 6, carbon atoms, preferably methyl and / or ethyl,
- x 1, 2 or 3, preferably 2 or 3, more preferably 3,

Extraordinary additional steps such as the reaction of a finished TPU with isocyanates and subsequent reaction of the isocyanate-modified TPU with silanes, such. taught in US 2002/0169255, are not required.
- the silane groups which are already integrated into the TPU in the production process, do not lead to crosslinking in the further processing of the TPU even before the actual shaping. This is surprising since the work-up of the TPU, e.g. granulation under water, optionally in the presence of moisture is carried out, which can be followed by drying at elevated temperatures. These moist-warm conditions usually support the crosslinking reaction of the silanes, which, however, only after the actual shaping, i. after extrusion, injection molding or spinning is desired.
- the crosslinkable thermoplastic polyurethane can preferably be prepared by reacting (a) isocyanates with (b) compounds reactive toward isocyanates having a molecular weight between 500 and 10,000 g / mol and (c) chain extenders having a molecular weight of 50 to 499 g / mol and compounds (i) which have at least two silicon-organic groups, if appropriate in the presence of (d) catalysts and / or (e) customary additives, preference being given to the ratio of the sum of the isocyanate groups of component (a) to the sum of isocyanate-reactive functions of components (b), (c) and (i) and also optionally (d) and (e) is between 0.7: 1 and 1.3: 1.
- This preferred ratio thus describes the molar ratio of all isocyanate groups to the sum of all isocyanate-reactive functions, ie reactive hydrogen atoms.

- an isocyanate group of component (a) has an active hydrogen atom, ie a function reactive toward isocyanates.
- the incorporation of the silanes can thus already take place during the production process of the TPU. If the preparation of the TPU already takes place in the presence of the silane, the molar ratio of the polyols and chain extenders (b) and (c) to the silanes (i) is preferably between 5: 1 and 20: 1, particularly preferably between 10: 1 and 15: 1.
- Thermoplastic polyurethane means that it is preferably a thermoplasti ⁇ cal elastomer based on polyurethane.
- a thermoplastic elastomer is an elastomer which, when repeatedly heated and cooled in the temperature range typical of the material for processing and use, remains thermoplastic.
- thermoplastic is meant the property of a plastic to soften in a typical temperature range for him repeatedly in the heat and to harden on cooling and be repeatedly formed in the softened state by flowing as a molded part, extrudate or forming part to semifinished or articles. After crosslinking via the silanes is the thermoplastic polyurethane. only conditionally thermoplastically processable.
