Core‐shell inorganic‐organic hybrid nanocomposites, Ti‐PMMAs are constructed applying the titanium‐oxo cluster (Ti 6 O 4 (BrC[CH 3 ] 2 COO) 8 (O i Pr) 8 , TiO; i Pr = isopropyl) as quasi‐spherical initiator for ATRP (atom‐transfer radical polymerization). Confirmed by UV‐Vis measurements and mechanical test, Ti‐PMMAs inherit the properties of both TiO cluster and polymers and show outstanding UV‐proof performance, high visible light transmittances, and excellent mechanical properties and processabilities. The elasticity and toughness of TiO‐polymer nanocomposites can be further optimized by simply tuning the polymer composites during the ATRP reactions. The admirable processability of the hybrid materials render us the capability to produce uniform nano‐coatings of Ti‐PMMAs and TiO 2 with thickness approaching to a challenging length scale, 10 nm.
