- the multiblock copolymers according to the invention containing the structural units of the formula I are distinguished from the starting products of the formulas II and III by an increased molecular weight, which is noticeable in a reduction in the melt index.
- the POM used homo- or copolymers of the formula II have (kg MVR values 190 ° C / 2.16, ISO 1133), in general melt indices greater than 2 cm 3/10 min, preferably from 5 to 200 cm 3/10 min, in particular from 24 to 70 cm 3 / 10min.
- the melting points of the POM homopolymers or copolymers of the formula II used are typically in the range from 100 to 175 ° C. (measured with DSC at a heating rate of 10K / min).
- the multiblock copolymers according to the invention can be used for molded parts of any kind, in particular for the production of fibers, foils, tubes, rods or profiles.
- the processing of the multiblock copolymers of the invention can be made by blow molding, injection molding or extrusion, or the molecular weight increase occurs at already formed 'bodies.
- the invention therefore also relates to the use of the multiblock copolymers for the purposes mentioned above.
- the co-component in the multiblock copolymers according to the invention generally has a favorable effect on the impact strength of the products, the use of further impact modifiers, such as elastomeric polyurethanes, is not absolutely necessary. Depending on the envisaged application, such components can, however, be added in individual cases. The mixing of such components into conventional POM homopolymers or copolymers can even be simplified, since the multiblock copolymers can act as phase mediators (compatibilizers).
- the invention also relates to the use of the multiblock copolymers as phase mediators in compositions containing polyoxymethylene homo- and / or copolymers, the use of the multiblock copolymers as impact modifiers and compositions comprising polyoxymethylene homo- and / or copolymers and the multiblock copolymers.
- the multiblock copolymers or compositions according to the invention can contain further additives known per se, which can be added during the manufacture or after the manufacture of the polymeric precursors or the multiblock copolymers.
- additives are processing aids, such as antioxidants, acid scavengers, formaldehyde scavengers, UV stabilizers, heat stabilizers, adhesion promoters, lubricants, nucleating agents or mold release agents, fillers, reinforcing materials or antistatic agents; or additives which impart a desired property to the molding composition, such as dyes and / or pigments and / or impact modifiers and / or additives which impart electrical conductivity; and mixtures of these additives, but without restricting the scope to the examples mentioned.
- the multiblock copolymers according to the invention can be processed by mixing the finely divided, for example powdered or granulated, components and subsequent thermoplastic processing, or by mixing the components in suitable heatable mixing units. Suitable mixing units and processes are described, for example, in: Saechtling, Kunststoff-Taschenbuch, Hanser Verlag, 27th edition 1998, on pages 202 to 217, to which reference is made.
- the advantageous processing temperatures are usually in the range from 180 to 230 ° C., in particular between 190 to 210 ° C.
- the raw materials. (POM powder, stabilizers, chain linkers, polymer co-component HX-D-XH and catalyst: a total of 50 g) were premixed in a plastic bag.
- the housing temperature of the kneading chamber of the Brabender PlastiCorder was set to 200 ° C and a filling funnel (accessory of the Brabender kneader) was placed on the kneading chamber.
- the powder mixture (50 g total) was poured into the funnel while the kneader was running (40 rpm) and then pressed into the kneading chamber by a displacer (wedge-shaped punch) with a bearing weight of 5 kg.
- the mixture began to melt and as soon as the melting process was complete (short-term torque drop), the filling funnel was removed and the lid with the purge gas supply line and the exhaust pipe was replaced instead. Now the recording of the torque began, which was stopped after a total of 60 minutes (after filling in the powder mixture). After opening the kneading chamber, the reaction mixture was removed for further investigation and characterization. Tables 1a and 1b below list the formulations used and the results of the characterization after 1 hour of kneading.
- Table 1b Characterization of the products after kneading for 1 hour at 200 ° C.
- the tests were carried out on a ZE 25 twin-screw extruder from Berstorff. A membrane pump MD 8 C Vacuubrand was connected to the vacuum dome.
- the starting materials (POM powder, polymer D, stabilizers, chain linkers and catalyst) were premixed in a RIOA powder mixer from Diosna and metered into the feed zone of the extruder via a S210 meter from KTron Soder.
- Tables 2a, 2b and 2c below show the recipes and parameters used in the extrusion tests and the results of the characterizations of the materials obtained.
