Abstract (en)
[origin: WO2010145741A1] The present invention relates to shape memory polymers characterized in that they comprise BiOCI pigments as X-ray contrast agents. Such doped polymers are used particularly in medical technology products, such as reinforcing pins for the spinal column, tooth root pins, as bone cement, and in catheter materials.
