A polymer is a large molecule of high molecular mass formed by the repetitive bonding of many small molecules called monomers.The process by which the monomers are transformed into polymers is called polymerisation.As polymers are single big size molecules, they are also called macromolecules. Each monomer normally contains two functional groups. Match List-I and List-II and select the correct answer using the codes below the lists: These include polymers like Bakelite and Melamine polymers. These are formed by the condensation of two or more monomers with the elimination of simple molecules like H2O, NH3, ROH, etc. Class.
