First, monofunctional and bifunctional P(MMA-co-GMA) copolymers were synthesized by ATRP. Subsequently, these copolymers were successfully used as macroinitiators for ATRP of POSS-containing methacrylate monomer. The process showed high initiation efficiency of macroinitiators and led to products with low dispersity. The synthesized block copolymers were characterized by size exclusion chromatography, 1H-NMR spectroscopy and their glass transition temperatures were determined by differential scanning calorimetry.
