In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis of Well-Defined Polyacrylonitrile by Atom Transfer Radical Polymerization, published in 1997-10-06, which mentions a compound: 19481-82-4, mainly applied to polyacrylonitrile synthesis atom transfer radical polymerization, Synthetic Route of C3H4BrN.
Well defined polyacrylonitrile (PAN) was synthesized by atom transfer radical polymerization (ATRP). The polymerization was carried out in ethylene carbonate at 44° with 2-bromopropionitrile as the initiator and CuBr/2,2′-bipyridine as the catalyst. Although first order kinetic plots displayed curvature after initially being linear, PAN with predetermined mol. weight (DPn = Δ[M]/[I]o) and low polydispersities (Mw/Mn < 1.1) were prepared The mol. weights, as determined by 1H NMR and MALDI, increased linearly with conversion but were higher than expected assuming quant. initiation. The polydispersities obtained from SEC and MALDI decreased with conversion to values as low as Mw/Mn = 1.04 and 1.01, correspondingly. If you want to learn more about this compound(2-Bromopropanenitrile)Synthetic Route of C3H4BrN, you may wish to communicate with the author of the article,or consult the relevant literature related to this compound(19481-82-4).
