How many of the following polymers given, come under the category of condensation polymers? Bakelite, Teflon, Nylon-6, Dacron, Polyisoprene, Melamine, Neoprene

Step-by-step solution

The given polymers are formed as follows : Bakelite These are made by the condensation reaction of formaldehyde and phenol in presence of either an acid or base, as a catalyst. It involves the formation of methylene bridges in ortho/ para position. On heating with formaldehyde, novolac undergoes cross-linking to form an infusible solid mass, which is known as bakelite. It is a condensation polymer. Teflon It is prepared by heating tetrafluoroethylene at high pressure in the presence of peroxides or ammonium peroxo
