Use of the RAFT technique has evolved from the use of a free RAFT agent i.e. the RAFT agent is not attached to the clay layers) to the use of RAFT agents anchored on the clay platelets. Moad and co-workers used RAFT-mediated polar polymers that are miscible with polypropylene (PP) and then melt blended both polymers i.e. polymers and PP) in the presence of sodium montmorillonite to yield PP-CNs. Salem and Shipp showed that the use of free RAFT agents to the prepare polystyrene-, poly(methyl methacrylate)- and poly(butyl acrylate)-clay nanocomposites by in situ intercalative polymerization in bulk led to products with well-controlled molecular weights and narrow...

RAFT polymerization or nitroxide-mediated polymerization (NMP) was used instead of ATRP for the synthesis of the block copolymer of polythiophene and polyisoprene or polystyrene, because ATRP generates materials containing traces of metals from the catalyst [146]. A block copolymer of P3HT and poly (perylene bisimide acrylate) was also synthesized by NMP from a polythiophene macroinitiator (Scheme 51) [147, 148]. This block copolymer is a crystalline-crystalline donor-acceptor block copolymer and shows microphase separation, implying efficient photovoltaic applications. A similar polythiophene macroinitiator for NMP was used for the synthesis of fullerene-grafted rod-coil block copolymers [149].
