Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2-Bromopropanenitrile, is researched, Molecular C3H4BrN, CAS is 19481-82-4, about Photochemically Induced ATRP of (Meth)Acrylates in the Presence of Air: The Effect of Light Intensity, Ligand, and Oxygen Concentration.COA of Formula: C3H4BrN.
Well-defined poly(Me methacrylate) (PMMA) and poly(Me acrylate) (PMA) are prepared via photochem. induced atom transfer radical polymerization (photoATRP) using ppm amounts of CuBr2/tris(2-pyridylmethyl)amine and CuBr2/tris[2-(dimethylamino)ethyl]amine catalyst complexes, resp., without degassing of polymerization mixture and with no need to introduce an external reducing agent to the system. The effect of ligand to CuBr2 ratio on kinetic and induction period during the polymerization of MMA and MA is investigated. The induction period is influenced also by the amount of oxygen in the polymerization system. Both the kinetics of MA polymerization and the induction period are affected by light intensity. Finally, the high livingness and initiation efficiency of the photoATRP system in the presence of air are proved by chain extension polymerizations The presented system is valuable from an industrial point of view, since after optimization, well-defined and high-molar-mass poly(meth)acrylates can be prepared without the necessity of degassing the system, while the polymerization can be proceeded quickly and without an induction period.
