**3. Conclusions**

The accelerating interest in living AROP-derived siloxanes has been spurred by the increasing drive to provide soft matter structures associated with tactile interaction and biocompatibility, particularly in the areas of contact lenses and biomimetic structures, and by these materials' ability enable control of nano-dimensional physical properties associated with "smart" particles and morphologies associated with self-assembly. Silicone macromers have had grea<sup>t</sup> impact in practical applications, primarily due to their ability to cross-over from the paradigm of inorganic siloxane chemistry to the greater paradigm of organic polymerization. Further, the elaboration of simple macromers into heterobifunctional monomers has created opportunities for polymers with new bulk phase properties, including ultra-high elongation and self-healing materials.
