A comparative study on photoinitiated solution copolymerization of Styrene (Sty), with acrylonitrile (AN) using pyrene, 1-acetylpyrene, and 1-(bromoacetyl)pyrene (BrPy) as initiators, showed that the introduction of a chromophoric moiety, bromoacetyl (-COCH2Br), significantly increased the photoinitiating ability of pyrene. The kinetics and mechanism of copolymerization of Sty with AN (Sty-co-AN) using BrPy as photoinitiator has been studied in detail. The kinetic data, inhibiting effect of benzoquinone, and ESR (ESR) studies suggest that the polymerization proceeds via a free radical mechanism. The system followed non-ideal kinetics (Rpα[BrPy]0.7[Sty]1.09[AN]1.01) and degradative solvent transfer reasonably explained these kinetic non-idealities. The co-monomer reactivity ratios calculated by using the Finemann-Ross and Kelen-Tudos models were r1 (Sty) = 0.39 and r2 (AN) = 0.05. The reactivity ratios strongly indicate that the 2 monomers enter in almost alternating arrangement along the copolymer chain. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5SDS of cas: 80480-15-5).
2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.SDS of cas: 80480-15-5
