Poly(silsesquioxanes) (PSSQs) show very promising results as nanocomposite fillers and low-dielectric films. In this study we developed a novel synthetic scheme to prepare organic-inorganic hybrid block copolymers based on atom transfer radical polymerization (ATRP) starting from functionalized PSSQ as initiating polymers. PSSQ was modified with a useful initiator group (2-Bromo-isobutyroic acid 5-(chloro-dimethyl-silanyl)-pentyl ester). For initial demonstration, we chose PMMA as an organic block. Besides the chemical composition, we are able to control the block ratios and block length of the hybrid polymer. Moreover, novel applications of PSSQ-PMMA hybrid block copolymer will be discussed. |
