Abstract
The present invention relates to shape-memory polymers which are distinguished by the fact that they comprise BiOCl pigments as X-ray contrast agents. Polymers doped in this way are used, in particular, in medical technology products, such as, for example, stiffening pins for the spinal column, tooth root cones, as bone cement and in catheter materials.
