- block copolymers suitable as compatibilizers are selected by the person skilled in the art for preparing the blends. It will be understood by those skilled in the art that a single type of compatibilizer is not equally well suited for all types of polymer blends.

In the case of the compatibilizers used according to the invention, even 0.05% by weight, based on the total amount of all components of the blend, may be sufficient. Too high a proportion should be avoided so that the compatibilizer does not adversely affect the properties of the blend. As a rule, amounts of from 0.05 to 10% by weight with respect to the total amount of all the components of the blend have proven successful. Preferably, the amount is 0.2 to 5 wt.%, Particularly preferably 0.3 to 3 wt.%, Very particularly preferably 0.4 to 2 wt.% And for example, about 0.5 wt.%.

- the temperature for mixing is chosen by a person skilled in the art and depends on the type of polymers used. On the one hand, the polymers should sufficiently soften, so that thorough mixing is possible. On the other hand, they should not be too thin, because otherwise sufficient shear energy input can no longer take place and, under certain circumstances, thermal degradation is also to be feared. As a rule, temperatures of 120 to 300 0 C can be applied, without the invention being limited thereto. It proves to be particularly advantageous here that the block copolymers used according to the invention have high thermal stability.
