The structure of polypropyne, showing atleast three repeating units has to be drawn; the general formula for the polymer has to be written. Concept Introduction: Polymers are macromolecules which are formed a by number of repeating units called monomers. Based on the techniques involved in preparation of polymers, it can be classified as addition polymer and condensation polymer. Addition polymers are formed by a number of additions of unsaturated monomers one after the other. Condensation polymers are formed when two compounds condense with each other by giving out small molecules (water or methanol) as by-products.
