    Abstract: A molding composition which comprises at least 50% by weight of the following constituents: a) from 0 to 99 parts by weight of polyamide, and b) from 1 to 100 parts by weight of polyamide elastomer, selected from the group of polyetheresteramide and polyetheramide, where the total of the parts by weight is 100 and where the molding composition comprises from 0 to 9% by weight of plasticizer, is used for the production of a molding for contact with a supercritical medium, and preferably for the production of an inner thermoplastics layer in a flexible pipe or rigid pipe, in which a supercritical medium is conveyed. Low or zero plasticizer content eliminates any significant occurrence of problems such as increased stiffness and longitudinal shrinkage.

    Abstract: In a method for the introduction of an inliner into a pipe or a pipeline, where the external diameter of the inliner is greater than the internal diameter of the pipe or of the pipeline, and where the action of an external force is used to reduce the cross section of the inliner prior to the introduction, the inliner is composed of a polyamide moulding composition which comprises at least 50% by weight of polyamide which is not PA11. The recovery behavior of said polyamides is similar to that of polyethylene usually used for this purpose.

    Abstract: A process for producing moldings with condensing-up of a polyamide molding composition whose polyamide component contains, as a result of the method of preparation, at least 5 ppm of phosphorus in the form of an acidic compound by means of a compound having at least two carbonate units, wherein a) from 0.001 to 10% by weight, based on the polyamide, of a salt of a weak acid is added to the polyamide molding composition prior to compounding or during compounding, b) a mixture of the finished composition and the compound having at least two carbonate units is prepared, c) the mixture is, if appropriate, stored and/or transported and d) the mixture is subsequently processed to produce the molding, with the condensing-up occurring only in this step, effects a significant increase in the melt stiffness combined with moderate processing presssures, which considerably simplifies, in particular, the production of hollow bodies and hollow profiles having large diameters.
