Definitions
- the present invention relates to a thermoplastic molding composition containing a polyalkylene terephthalate and a polyimide, the molding composition having a single glass transition temperature.
- the present invention further relates to their use and also to fibers, films and moldings which are produced from the molding compound.
- Polyalkylene terephthalates are polyesters and have thermoplastic properties. They are characterized by a wide range of possible applications. Polyethylene terephthalate (PET) in particular plays an important role here. PET is used, among other things, for the production of plastic bottles (PET bottles), foils and textile fibers. Polybutylene terephthalate (PBT) also has good properties. PBT is preferred over PET because of its better process behavior, which is particularly important in injection molding processes. However, the raw materials for PBT are more expensive.
- the disadvantage of polyalkylene terephthalates is their comparatively low glass transition temperature (T g ).
- T g glass transition temperature
- the temperature range for the hard-elastic state in which polyalkylene terephthalates are frequently used is restricted and it is desirable to extend this temperature range or to increase the glass transition temperature.
- One object of the present invention is therefore to provide such a molding compound.
- thermoplastic molding composition containing a polyalkylene terephthalate and a polyimide, the molding composition having a single glass transition temperature in the DSC measurement.
- molding compound In the context of the present invention, the term “molding compound” is used in accordance with the general understanding. Accordingly, molding compounds represent unshaped products that can be shaped by mechanical forces in a certain temperature range. Examples of suitable processes are extrusion, injection molding and compression molding.
- the glass transition temperature (T g ) is known to the person skilled in the art and represents a characteristic physical quantity of a polymer or a mixture of several polymers Temperature changes a solid polymer or glass into a rubbery to viscous state. This can be determined, for example, by dynamic differential calorimetry (DSC).
- DSC dynamic differential calorimetry
- thermoplastic molding composition according to the invention has a single glass transition temperature.
- a single glass transition temperature is to be understood in the context of the present invention, that the polymers polyimide and polyalkylene terephthalate necessarily contained in the molding compound form a mixed phase with a T g value between the T g values of the component having.
- Further auxiliaries that can be contained in the thermoplastic molding composition according to the invention can themselves be polymeric, amorphous in nature and have a glass transition temperature, which, however, are not to be taken into account in the sense of having “a single glass transition temperature”.
- Such a single glass transition temperature T g preferably has a value of at least 45 ° C.
- a T g value of at least 50 ° C. is more preferred.
- a T g value of at least 60 ° C. is also more preferred.
- a T g value of at least 70 ° C. is also more preferred.
- a T g value of at least 80 ° C. is also more preferred.
- thermoplastic molding composition is in the range starting with the T g value of the polyalkylene terephthalate and ends at the T g value of the polyimide.
- the difference between the T g value of the polyalkylene terephthalate and the T g value of the polyimide before they were introduced into the molding composition according to the invention is preferably at least 25 ° C., more preferably at least 50 ° C., more preferably at least 75 ° C., more preferably at least 100 ° C, more preferably at least 125 ° C, more preferably at least 130 ° C, more preferably at least 140 ° C.
- the difference (increase) between the T g value of the polyalkylene terephthalate before this was introduced into the molding compound according to the invention and the T g value of the polyalkylene terephthalate in the molding compound according to the invention (mixed phase) is at least 5 ° C., further preferably at least 10 ° C, more preferably at least 15 ° C, more preferably at least 20 ° C, more preferably at least 25 ° C, more preferably at least 30 ° C, more preferably at least 40 ° C.
- the thermoplastic molding composition according to the present invention contains a polyalkylene terephthalate.
- a polyalkylene terephthalate This is preferably a polyethylene, a polytrimethylene or a polybutylene terephthalate or a mixture thereof. It is more preferably polybutylene terephthalate.
- Polyalkylene terephthalates (A) are commercially available and can have at least partially amorphous forms. In the context of the present invention, a glass transition temperature can be assigned to the polyalkylene terephthalate.
- Ultradur® B4500 is an example.
- polyethylene terephthalates are sold, for example, as the Petra® series by BASF.
- thermoplastic molding composition according to the present invention also contains a polyimide (B).
- Polyimides (B) are thermally and mechanically very stable polymers. In order to be able to use these polymers as thermoplastics, irregularities are built into the polymer chain. Here, for example, branches can be provided in the polymer structure. Through these branches, the crystallinity can be avoided and the T g value can be adjusted.
- Polyimides can be formed, for example, from: b1) at least one isocyanate, the isocyanate having at least two isocyanate groups (“polyisocyanate”), preferably with at least an average of more than two isocyanate groups per molecule, or b2) at least one amine, the amine having at least two Has amino groups (“poly amine”), preferably with at least an average of more than two amino groups per molecule and b3) at least one polycarboxylic acid with at least three, preferably at least four COOH groups, in particular exactly 4 per molecule or its anhydride, in particular the dianhydride .

- Polyimide (B) can have a molecular weight Mw in the range from 1,000 to 200,000 g / mol, at least 2,000 g / mol being preferred.
- Polyimide (B) can have at least two imide groups per monomer unit; preference is given to at least 3 imide groups per monomer unit.
- polyimide (B) can have up to 1,000 imide groups per molecule, preferably up to 660 per molecule.
- the specification of the isocyanate groups or the COOH groups per molecule in each case denotes the mean value (number average).
- Polyimide (B) can be composed of structurally and molecularly uniform molecules. However, it is preferred if polyimide (B) is a mixture of molecularly and structurally different molecules, for example visible from the polydispersity Mw / Mn of at least 1.4; Mw / Mn is preferably from 1.4 to 50, more preferably from 1.5 to 10.
- the polydispersity can be determined by known methods, in particular by gel permeation chromatography (GPC). A suitable standard is, for example, polymethyl methacrylate (PMMA).
- the polyimide (B) can also have terminal or pendent functional groups at least three, preferably at least six, particularly preferably at least ten terminal or pendent functional groups. Functional groups in the polyimide (B) can be anhydride or acid groups, for example and / or act free or masked NCO groups.
- Polyimides (B) preferably have no more than 500 terminal or pendent functional groups, preferably no more than 100.
- Polyisocyanate (b1) can be selected from any polyisocyanates which on average have at least or preferably more than two isocyanate groups per molecule, which can be blocked or preferably free.
- Trimeric or oligomeric diisocyanates for example oligomeric hexamethylene diisocyanate, oligomeric isophorone diisocyanate, oligomeric tolylene diisocyanate, oligomeric diphenylmethane diisocyanate - so-called polymer MDI - and mixtures of the aforementioned polyisocyanates are preferred.

- oligomeric tetramethylene diisocyanate and oligomeric isophorone diisocyanate are in many cases not present as a pure trimeric diisocyanate, but rather as a polyisocyanate with an average functionality of 3.6 to 4 NCO groups per molecule.
