Description

[0001] 2024PF30063-Abroad - 1 -The present invention relates to a polycarbonate, polyester carbonate, and / or polyester composition containing an olefin copolymer and a special salt, a process for producing a thermoplastic molding compound from the composition, the molding compound itself produced by such a process, and molded parts containing this molding compound. Furthermore, the invention relates to the use of the special salt to improve the melt flowability of thermoplastic molding compounds produced from compositions containing polycarbonate, polyester carbonate, and / or polyester and an olefin copolymer, and to improve the multiaxial ductility of molded parts made from such compositions or from thermoplastic molding compounds produced therefrom.Molding compounds containing polycarbonates, polyester carbonate, and / or polyester have been known for many years. These compounds are used to produce molded parts for a wide variety of applications, such as in the automotive, construction, and electronics sectors. Polymer blends can be produced by mixing polycarbonates, polyester carbonate, and / or polyesters with other polymeric components and additives in the melt (compounding). The properties of such polymer blend molding compounds and the resulting molded parts can be varied over a wide range and adapted to the requirements of the respective application by appropriately selecting their composition and manufacturing conditions. An interesting group of potential blend partners is the group of polyolefins.Due to their semi-crystalline nature and low glass transition temperatures, these polymers offer improved mechanical and rheological properties as well as resistance to chemical influences. Contact with chemicals such as fats or oils is particularly critical when the molded parts produced from these compounds are under stress. Experts therefore refer to this as stress crack resistance. This property is highly relevant, for example, for unpainted components because they lack a protective coating. Furthermore, the surface appearance is determined by the material itself and not by the coating present on painted components. For many applications, a highly glossy surface is required. 2024PF30063-Abroad -. 2 -For the field of electromobility, plastic materials are subject to additional requirements. When the polymer material comes into contact with current-carrying components such as conductor tracks, high tracking resistance is a crucial property. Tracking currents can enable charge transfer over long distances across the plastic surface, potentially causing short circuits and fires. Furthermore, high tracking resistance allows for a reduction in the spacing between conductor tracks and thus the overall component size. Tracking resistance can be expressed using the CTI (comparative tracking index), with a higher CTI value indicating better suitability of the materials for contact with current-carrying components. Polyolefins generally exhibit a higher CTI value than, for example, polycarbonate, and are therefore promising blending partners for this reason as well.This is particularly relevant for unpainted components, where sufficient tracking resistance cannot be controlled by a specially selected surface coating. In practice, however, the use of polyolefins as blend partners for polycarbonates, polyester carbonates, and polyesters is limited. It has been shown that polyolefins must be used in certain minimum quantities to realize the aforementioned advantages. However, polyolefins are not miscible with polycarbonate in these quantities, even by dispersion in the melt. Due to this often-present partial or complete incompatibility, separate phases form in the polycarbonate, polyester carbonate, or polyester blends.Depending on the proportions of the respective polymer components, polycarbonate, polyester carbonate, or polyester, for example, forms a matrix phase in which the olefin polymer is present in the form of more or less finely dispersed, microscopically visible polymeric phases. The phase interfaces then represent weak points with regard to mechanical properties, and material delamination can also occur. Improved compatibility is achieved with copolymers through the copolymerization of olefins with more polar monomers, such as acrylic acid and methacrylic acid, or the corresponding esters, i.e., acrylates and methacrylates, which are more miscible with polycarbonate, polyester carbonate, or polyester. Such copolymers are already described in the prior art as blend partners for polycarbonates.US 2021 / 0163739 A1 discloses a copolymer of ethylene and acrylate(s) with a melt flow index (MFI) of greater than or equal to 50 g / 10 minutes, obtained by radical copolymerization under high pressure in a tubular reactor, and processes to 2024PF30063-Foreign -. 3 -its use. Furthermore, a thermoplastic composition is disclosed here, which is intended in particular for extrusion or injection molding and contains one or more such copolymers of ethylene and acrylate(s) in a content in the range of 0.1 to 20 wt.% as well as one or more thermoplastic polymers such as polycarbonate. EP 0216267 A1 discloses thermoplastic compositions suitable for the production of molded parts and based on mixtures of an aromatic polycarbonate and a copolymer of ethylene and acrylic or methacrylic acid. It is described that articles produced from these compositions are more resistant to delamination than corresponding compositions based on mixtures of polycarbonate and polyethylene.EP 0119531 A2 discloses thermoplastic compositions containing an aromatic polycarbonate, an olefinic polymer or copolymer, and a third component, which is a copolymer of an olefin and an acrylate, methacrylate, acrylic acid, or methacrylic acid. The third component improves impact strength and weld line strength. EP 0271701 A2 discloses a composition containing at least one high molecular weight aromatic polycarbonate and an impact-modifying, gasoline-solvent-resistant amount of an ethylene alkyl acrylate, in which the ethylene constitutes about 55 to 75 percent by weight and the alkyl acrylate about 25 to 45 percent by weight, based on the ethylene alkyl acrylate polymer.To improve the mechanical properties, especially impact strength and weld line strength, and to reduce material delamination of polymer blends containing polycarbonate and polyolefins or olefin-containing copolymers, the use of certain catalysts is further proposed. US 4,496,693 discloses a composition containing a) an aromatic carbonate polymer, b) a polyolefin or a polyolefin modified with acrylate, methacrylate, acrylic acid, or methacrylic acid in sufficient quantity to modify the aromatic carbonate polymer for impact resistance, and c) a catalyst quantity sufficient to make a and b compatible, selected from the group consisting of basic compounds of alkali or alkaline earth metals. WO 2020 / 212229 A1 discloses a process for producing a thermoplastic molding compound containing an aromatic polycarbonate and another polymer having functional groups. 2024PF30063-Foreign -.4 -The process involves melting and mixing the polymers in the presence of a phosphonium salt as a catalyst. However, the aforementioned prior art does not disclose how an overall advantageous property profile for unpainted applications in the field of electromobility can be achieved. It was therefore desirable to provide a composition for producing a thermoplastic molding compound, wherein, compared to polycarbonate, the molding compound exhibits improved rheological properties, i.e., lower melt viscosity and thus improved processability in injection molding, and the molded parts exhibit better tracking resistance and higher chemical resistance while simultaneously maintaining a high gloss level and good mechanical properties, in particular low-temperature ductility as measured by the maximum energy absorption in the multiaxial puncture test at preferably -30°C.Preferably, a CTI of 600 V should be achieved, determined according to the rapid test method described in the example part, based on IEC 60112:2009.

The olefin is then covalently incorporated into the polymer chain of the copolymer.For all other monomeric compounds involved in the structure of components A and B, the meaning of "derived from" within the scope of the present invention is to be understood analogously. Preferred olefins as components of the copolymers are α-olefins and particularly preferably have between 2 and 10 carbon atoms and can be unsubstituted or substituted with one or more aliphatic, cycloaliphatic, or aromatic groups. Particularly preferred olefins are selected from the group comprising ethene, propene, 1-butene, 1-pentene, 1-hexene, 1-octene, and 3-methyl-1-pentene.

Mixtures of the described olefins are also suitable. 2024PF30063-Foreign -. 16 -The production of polyolefins has long been known to those skilled in the art. Polyolefins are produced by chain polymerization of the aforementioned olefins, for example, by radical polymerization. The polymerization can be carried out, for example, at pressures of 1 to 3000 bar and temperatures between 20°C and 300°C, optionally using a catalyst system. Suitable catalysts include, for example, mixtures of titanium and aluminum compounds as well as metallocenes. By changing the polymerization conditions and the catalyst system, the number of branches, the crystallinity, and the density of the polyolefins can be varied over a wide range. These measures are also familiar to those skilled in the art.

A vacuum of 100 mbar (absolute) was applied. The residence time of the melt mixture in the extruder was approximately 30 s. The molded parts for the tests were produced at a melt temperature of 260°C (optical test pieces) or 280°C (other test pieces) and at a mold temperature of 80°C on an Arburg 270 E injection molding machine. 2024PF30063-Abroad -. 30 - Testing of the molding compounds and the molded parts produced from the molding compounds. The melt viscosity was determined at a temperature of 260°C and a shear rate of 1000 s⁻¹. -1According to ISO 11443 (2014 version). Stress cracking (ESC) resistance in rapeseed oil at room temperature served as a measure of chemical resistance. The time to stress crack-induced failure was determined by the occurrence of edge cracks or complete fracture of a test specimen measuring 80 mm x 10 mm x 4 mm, injection-molded at a melt temperature of 280°C, subjected to an external edge fiber strain (Rf) of 2.4% using a clamping template, and fully immersed in rapeseed oil. The measurement was performed in accordance with ISO 22088 (2006 version). The maximum test duration was 24 hours. If no fracture of the test specimen was observed within this period, the test was considered passed ("yes" in the results tables).Surface gloss was measured in reflection at a viewing angle of 60° using a Haze-Gloss gloss meter from BYK-Gardner GmbH (Geretsried, Germany) according to DIN 67530 (1982 version) on test specimens measuring 60 mm x 40 mm x 4 mm, injection-molded at 260 °C. A highly polished injection mold was used. Tracking resistance was tested for the compositions described here using the rapid test method based on IEC 60112:2009. For this purpose, a 0.1% ammonium chloride test solution (395 Ω·cm resistance) was applied dropwise between two electrodes spaced 4 mm apart to the surface of test specimens measuring 60 mm x 40 mm x 4 mm at 30-second intervals. A test voltage was applied between the electrodes, which was varied during the test. The first test specimen was tested at a starting voltage of 300 V or 350 V.A maximum of 50 drops (one drop every 30 seconds) were applied per voltage, provided no leakage current > 0.5 A occurred over 2 seconds or the sample caught fire. After 50 drops, the voltage was increased by 50 V, and a new test specimen was tested at this higher voltage according to the previously described procedure. This process was continued until either 600 V was reached or a leakage current or fire occurred. If either of the aforementioned effects occurred with fewer than 50 drops, the voltage was reduced by 25 V, and a new test specimen was tested at this lower voltage. The voltage was reduced until the test with 50 drops was passed without leakage current or fire. This procedure thus determined the maximum possible voltage at which a composition of 50 drops of the test solution could withstand the test without the occurrence of a leakage current.Finally, to confirm the determined maximum voltage, four further test specimens were tested with 50 drops each. This confirmed value is given as CTI in the examples. A 100-drop value was not determined; therefore, the "rapid test method based on" the aforementioned standard is used. 2024PF30063-International -. 31 - To assess material ductility under multiaxial loading at low temperatures, a puncture test according to ISO 6603-2 (2002 version) was performed at -30°C on ten specimens each, measuring 60 mm x 60 mm x 2 mm. The arithmetic mean of the total energies measured in the ten individual tests serves as a measure of material ductility under multiaxial loading.

The melt viscosity, tracking resistance, and mechanical properties are also improved by the use of component C2 compared to a composition without component C2 (comparative example V4). Inventive example 10 shows that a combination of the also inventive component B3 with component C2 in a proportion of 0.025 parts by weight also fulfills the objective. Without component C2, the objective is not fulfilled (comparative example V6).The prior art describes the use of component C1 to improve mechanical properties. However, a combination of component B3 with component C1, in the lower weight fractions known from the prior art (0.0005, Comparative Example V7), cannot fulfill this objective, nor can the component C2 according to the invention in these lower weight fractions (Comparative Example V9). Increasing the weight fraction of C1 to 0.025 also fails to achieve the objective, as although the mechanical properties are improved, the tracking resistance decreases (Comparative Example V8). Components containing methacrylic acid-guided structural units are also disclosed in the prior art (components B4 and B5).However, in combination with the inventive component C2, these components do not achieve the objective of achieving improved melt viscosity and satisfactory gloss levels compared to polycarbonate (V1 and V2) (comparative examples V11 and V12). Inventive examples 13 and 14 show that structurally analogous and inventive components C3 and C4 also achieve the objective, whereas comparative examples V15 and V16, using structurally analogous but non-inventive components C5 and C6 respectively, do not achieve the objective with regard to mechanical properties.

The gloss level, while still within the desired minimum range, is somewhat lower and therefore less advantageous than with component B3. Inventive examples 18–21 show that the technical objective is achieved with a large proportion of component B, based on a total of 100 parts by weight of components A and B. However, the mechanical properties become less advantageous with increasing weight fractions of component B with respect to the total energies in the puncture test. Conversely, the melt viscosity decreases with increasing proportion of component B, resulting in improved melt flowability.A structurally analogous component B7, with the same proportion of methyl acrylate and also produced in a tubular reactor, fulfills the objective with a higher melt flow index of 7 g / 10 min. Components B8 and B9, with a higher methyl acrylate content, fulfill the objective (Examples 23-25 ​​according to the invention), although their mechanical properties are less advantageous than in Example 10 using component B3. However, the melt viscosity is lower. Examples 26 and 27 according to the invention show that the objective is still fulfilled even with a lower weight fraction of component C of 0.01 parts by weight.
