Self-reinforcement in polymers means improving the mechanical properties through orientation of the macromolecules, i.e. through alignment in one or two preferred directions. Their production and use has been state of the art with many semi-crystalline thermoplastics (films and fibers of polyethylene (PE), polypropylene (PP), polyamide (PA) and polyethylene terephthalate (PET)). Applications in injection molding are developed by Ehrenstein [1]. Within the trans-regional collaborative research center SFB/TR TRR 30, self-reinforcement of an amorphous polycarbonate film was achieved by stretching. In this way, an increase in strength and stiffness was produced without the help of any additives. The stretching was performed on a monoaxial stretching unit in the narrow gap. Here, by varying the stretching ratio, rate and temperature, the mechanical properties can be improved. Apart from developing the production process, the main focus here was on characterizing the stretched polycarbonate films. The stretched polycarbonate combines very good mechanical properties with outstanding transparency compared to other materials.
