WebSep 1, 2024 · The IR spectrum of acetophenone (phenyl methyl ketone) is also shown in Figure 7. The carbonyl stretch, labeled A, is at 1686, while the C-C-C stretch, labeled B, is at 1266. For aromatic ketones, generally the C-C-C stretch falls between 1300 and 1230. Note that these are the two most intense peaks in the spectrum. WebUnsaturated polyester toughened Epoxy was developed. Epoxy resin had toughened by weight fraction of 10, 20, 30, and 40 wt. % unsaturated polyester. FTIR spectroscopy has been used to investigating the intermolecular hydrogen bonding. Unsaturated polyester–epoxy matrices were characterized for their thermal properties. WebJul 1, 2024 · The chemical structure of a common polymer, polyethylene, is seen in Figure 1.
