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 Synthesis of Styrene-Acrylonitrile Copolymers and Related Block Copolymers by Atom Transfer Radical Polymerization, the main research direction is styrene acrylonitrile atom transfer radical polymerization initiator catalyst; macroinitiator styrene acrylonitrile block copolymer synthesis.Formula: C3H4BrN.
Atom transfer radical polymerization (ATRP) was successfully applied to the synthesis of styrene-acrylonitrile (SAN) copolymers of predetermined mol. weights and low polydispersities. The monomers were copolymerized under azeotropic conditions (ca. 63 mol % styrene and 37 mol % acrylonitrile) in bulk using mono- and difunctional alkyl halide initiators such as 2-bromopropionitrile, 1-phenylethyl bromide, Me 2-bromopropionate, poly(ethylene oxide) monomethyl ether 2-bromopropionate, and the bis(2-bromopropionate) esters derived from poly(ethylene oxide), poly(propylene oxide), or poly(ε-caprolactone) diols of various mol. weights in combination with two catalytic systems: CuBr/2,2′-bipyridine (bpy) and CuBr/N,N,N’,N”,N”-pentamethyldiethylenetriamine (PMDETA). The synthesized copolymers had high chain end-functionalities, as proven by further chain extension with styrene, Bu, tert-Bu, or glycidyl acrylate, and Me methacrylate. In the last case, the reaction in the presence of CuBr/bpy led to a block copolymer of high polydispersity, which was decreased to Mw/Mn = 1.5 using halogen exchange (i.e., CuCl/bpy as the catalytic system). All other block copolymers (including di-, tri-, and pentablock copolymers) had narrow mol. weight distributions (Mw/Mn = 1.1-1.4).
