Many simple hydrocarbons, such as ethylene and propylene, can be transformed into polymers by adding one monomer after another to the growing chain. Within each section, polymers are listed in alphabetical order, with copolymers placed in a section corresponding to the majority monomer in their compositions. This group includes natural rubber, and related materials, as well as the large number of synthetic polymers made with diene monomers. Natural rubber: Natural rubber is a linear polymer of isoprene (2-methyl-1, 3-butadiene) and is also called as cis – 1, 4 – polyisoprene. • The monomers are held together by a certain kind of bond (such as an amide bond) and a molecule is eliminatedin the process (such as a water molecule). Also, they can be classified into polymer backbone, so we find these groups: polyesters, polysaccharides, polycarbonates, polyamides, and vinyl polymers. Likewise, the very large molecules that are found in living things (and therefore in our food!) NCERT Solutions, NCERT Exemplars, Revison Notes, Free Videos, CBSE Papers, MCQ Tests & more. They, have very low coefficients of friction and have outstanding chemical and thermal resistance properties. For instance, polypropylene forms when propene monomers join one after the other. The repeating structural unit of most simple polymers not only reflects the monomer(s) from which the polymers are constructed, but also provides a concise means for drawing structures to represent these macromolecules. These molecules, which are called oligomers, can then further react with each other through their free functional groups. Learning Outcomes: • You should be able to: • List examples of natural polymers and their monomers, • Draw the structural formula of natural rubber, • Polymer is made up of macromolecules which contain repetitive small unit (monomer) in a long chain.
