Polymers are molecules of high molecular mass formed by joining together large numbers of small molecules, called monomers. There are two general methods of creating polymers. In addition polymerization, monomers couple through the opening of their multiple bonds, as seen in the formation of polyethylene.

Polymers are molecules of high molecular mass formed by joining together large numbers of small molecules, called monomers. There are two general methods of creating polymers. In addition polymerization, monomers couple through the opening of their multiple bonds, as seen in the formation of polyethylene.(Figure 1) In condensation polymerization, two monomers join by the elimination of a small molecule such as water, as seen in the formation of proteins from amino acids. (Figure 2) Figure H H Addition Polymerization H H Ethylene H H HHH T T T C-C-C-C--- T HH H H Polyethylene 1 of 2 Part A The repeat unit of a polymer is the smallest section of the polymer that includes all of the original monomers and is identically repeated end to end along the entire polymer chain. Draw the repeat unit of the polymer that results via a condensation reaction, as shown in Intro figure 2, between the diacid and the diamine shown. HO Terephthalic acid + OH H₂N NH₂ 1,1-Ethanediamine To indicate that the polymer repeats, leave the atom at each end of the repeat unit with one less bond. For example, leave a carbon atom with three bonds or a nitrogen atom with two bonds. Draw the molecule by placing atoms on the grid and connecting them with bonds. ► View Available Hint(s)
