Well‐defined macromolecular composites have been prepared by living carbocationic polymerization of isobutylene in combination with other conventional techniques. The products were designed for biomedical uses as 1) intervertebral disc replacement, 2) improved impact‐ and fatigue‐ resistant bone cements, 3) delayed drug release reservoirs, and 4) small diameter nonthrombogenic vascular grafts. The syntheses are out‐lined, and the novelty, main characteristics and properties of these unique materials are summarized. The era of designed biomaterials is upon us.
