Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Reactive & Functional Polymers called Synthesis of uniform polymer microspheres with “”living”” character using ppm levels of copper catalyst: ARGET atom transfer radical precipitation polymerisation, Author is Bicak, Tugrul Cem; Cormack, Peter A. G.; Walker, Calum, which mentions a compound: 7789-45-9, SMILESS is [Cu+2].[Br-].[Br-], Molecular Br2Cu, Safety of Cupric bromide.
The first example of activators regenerated by electron transfer atom transfer radical polymerization (ARGET ATRP) under precipitation polymerization (PP) conditions is reported. This new method for polymer synthesis (called ARGET ATRPP) requires only very low levels of metal catalyst for success, a distinctive feature that enables the production of uniform polymer microspheres under reversible-deactivation radical polymerization control. The influence of the polymerization conditions (monomer concentration, reaction time, initiator and catalyst concentrations) on the polymerizations and microsphere products were investigated and optimized. The ARGET ATRPP methodol. was used to prepare polymer microspheres with narrow particle size distributions and mean particle diameters in the micron-size range, under dilute monomer conditions (2%) while using very low copper catalyst concentrations (down to 1.7 ppm). The “”living”” characteristics of the polymer microspheres enabled poly(Me methacrylate) brushes to be grafted-from the microspheres directly without the need for any addnl. surface functionalization step to immobilize initiator moieties.
There is still a lot of research devoted to this compound(SMILES：[Cu+2].[Br-].[Br-])Safety of Cupric bromide, and with the development of science, more effects of this compound(7789-45-9) can be discovered.
