摘要： Stretched filaments based on aromatic polyethers, wherein the filaments have been stretched at a temperature between glass transition temperature and melting point and wherein the filaments are cooled down to below the glass transition temperature under full tensile load and a process for production thereof and use thereof.

摘要： A pipe, the inner surface of which is lined with a thermoplastic layer, is produced by a process comprising the following steps: a) a metal pipe is provided, b) a tubular inliner composed of a thermoplastic material is provided, c) a tape is cohesively helically bonded to the inliner, wherein the region of the contact surface of the tape consists of a moulding composition or an adhesive which adhere firmly to the surface of the inliner, and wherein the region of the opposing surface of the tape consists of a moulding composition or an adhesive which adhere firmly to the metal of the pipe, wherein the tape contains unidirectional reinforcing fibers; d) the cross section of the inliner is optionally reduced by exposure to an external force, e) the inliner is inserted into the metal pipe, f) by means of contact pressure and optionally heat, the inliner and metal pipe are firmly bonded to each other. Relative movements between the metal pipe and inliner are thereby prevented; the inliner also has high safety against collapse. The pipe is used to produce a routed pipeline.

摘要： Stretched filaments based on linear, branched or cyclic, aliphatic or semiaromatic polyamides, wherein the filaments have been stretched at a temperature between glass transition temperature and melting point and wherein the filaments are cooled down to room temperature under full tensile load.
