synthesis of well-known raft agent for living polymerization of 2-hydroxyethyl methacrylate (hema)

Developing new nanostructured materials, particularly supramolecular polymers, with specific properties, is at the heart of many ongoing research projects. in recent years, the reversible addition-fragmentation chain transfer (raft) process are much more suitable technique for control radical polymerization (crp) that produces high molecular weight (mw) polymers with a narrow polydispersity index (pdi). this polymerization technique is known as a powerful and suitable method for the polymerization of complex polymeric architectures in non-aqueous medium. one of the most widely used raft agents is bis(thiobenzoyl)disulfide (btbd). this product is a suitable and effective agent for 2-hydroxyethyl methacrylate (hema) polymerization. using this raft agent with special properties, the polymerization conditions of hema proceed in such a way that it can be categorized in living polymerization. in this work, the btbd has been synthesized, as a raft agent for the living polymerization of hema. the btbd w:as char:acterized by fourier transform infrared spectroscopy (ftir) and hydrogen nuclear magnetic resonance (1h-nmr). in the next stage, by using this raft agent, polymerization of hema was performed via the conditions of living polymerization.
