Further details can be found in the IUPAC Purple Book.3 2) Basic Concepts The terms polymer and macromolecule do not mean the same thing. The main difference between polymer and macromolecule is that polymers contain repeating units that represent the monomers whereas not all macromolecules have a monomer in their structure. A single polymer molecule may consist of hundreds to a million monomers and may have a linear, branched, or network structure. A polymer will always have a single repeating unit. Manufactured polymers include nylon, polyvinyl chloride (better known as PVC) and many types of plastics. In a polymer this is not possible; the molecules are chains containing potentially millions of formula units. As an example of cross-linking, sulfhydryl (-S-H) groups in two cysteine amino acid units in polypeptide chains can bond together to make a disulfide bridge (-S-S-) joining the chains together. Natural polymers include rubber, silk and cellulose (found in plants and used to make paper, for example). Dimer C.) Trimer D.) Polymer? Solution for Five different repeating units are found in the polymer obtained by cationic polymerization of 4-methyl-1-pentene.

In end group analysis, we use 1 H NMR measurements to determine the ratio of a specific proton in the repeat units to a specific proton in the end group. In copolymers there are two or more types of repeat unit, which may be arranged in alternation, or at random, or in other more complex patterns. Poly(vinylidene fluoride) , -[-CH 2-CF 2-] n - , must have an average molecular weight of more than 10,000 to be classified as a polymer. Ask Question Asked 2 years, 9 months ago. Many polymers are made of repeat units derived from natural gas or coal or crude oil. Polymer is a term used to describe large molecules consisting of repeating structural units (monomers) connected by covalent chemical bonds. There is, however a repeating unit in a polymer - the monomer from which it was made.
