Polyester ftir spectrum
WebIn this work, FTIR spectroscopy was applied to the determination of crystalline content in an aliphatic polyester. To this goal, a range of wavelengths (from 560cm-1 to 680cm-1), non conventional for this kind of polymers, was selected by analyzing spectra collected during isothermal crystallization tests. A deconvolution of the IR WebJul 1, 2024 · The chemical structure of a common polymer, polyethylene, is seen in Figure 1. FIGURE 1: The chemical structure of polyethylene. Polyethylene is named by appending “poly-” to the name of the monomer “ethylene.”. The repeat unit in polyethylene is the CH 2 or methylene group. Note from Figure 1 that the chemical structure of a polymer is ...
