    1 The monomer for POM is shown in Fig. B. The major peak at wavenumber -1 903 cm is due to the C-O-C symmetric stretch absorption. The peak at wavenumber 1097 cm-1 is due to the C-O-C asymmetric stretch. The peak at wavenumber 2923 cm-1 is due to the CH2-O asymmetric stretch. All of these vibration modes are indications of the specific molecular bonding within the sample and can be used to identify the material. TM Fig. B - Poly(oxymethylene) or POM or Delrin monomer.

    Polymer Essay: Plexiglass Many of the glass screens and windows we see today are not really made of glass. They are made of plexiglass. Plexiglass is not related to the chemical structure of glass at all. It is an organic polymer. Today this polymer is used in all sorts of applications. The formation of plexiglass was begun in 1930‚ at McGi11 University by William Chalmers‚ a research student. He polymerized methacrylic ethyl ester and methacrylic nitirile‚ creating a clear plastic paste

    (PVC). This material was made in 1872 by German chemist Eugen Baumann on accident. Polyvinyl Chloride is made with Chlorine (Cl) and ethylene. When these two are combined ( at extremely high temperatures) they create vinyl chloride monomer. The vinyl chloride monomer can then be polymerized to make polyvinyl chloride. Polyvinyl Chloride is then turned into what we call “synthetic leather”. Chlorine is found in the ocean water‚ as a part of sodium chloride (NaCl). It’s also found in the earth’s crust

    Institute of Higher Education 14 March 2018 Abstract Biological molecules are part of Introduction Biological molecules are formerly known as macromolecules. Macromolecules are large molecules that are formed from smaller molecules called monomers (Ellisman‚ 2014). They are formed by dehydration reactions‚ in which a water molecule is removed during the formation of bonds (Wayne Huang‚ 2015). Biological molecules are organic‚ indicating that they contain carbon and hydrogen atoms (Gair‚ 2013)
