Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 19481-82-4, is researched, Molecular C3H4BrN, about Copper(0)-mediated living radical polymerization of acrylonitrile: SET-LRP or AGET-ATRP, the main research direction is polyacrylonitrile living radical polymerization catalyst.HPLC of Formula: 19481-82-4.
Cu(0)-mediated living radical polymerization was first extended to acrylonitrile (AN) to synthesize polyacrylonitrile with a high mol. weight and a low polydispersity index. This was achieved by using Cu(0)/hexamethylated tris(2-aminoethyl)amine (Me6-TREN) as the catalyst, 2-bromopropionitrile as the initiator, and DMSO as the solvent. The reaction was performed under mild reaction conditions at ambient temperature and thus biradical termination reaction was low. The rapid and extensive disproportionation of Cu(I)Br/Me6-TREN in DMSO/AN supports a mechanism consistent with a single electron transfer-living radical polymerization (SET-LRP) rather than activators generated by electron transfer atom transfer radical polymerization (AGET ATRP). 1H NMR anal. and chain extension experiment confirm the high chain-end functionality of the resultant polymer.
