Identify the monomer in the following polymeric structure : `[-CH_(2) - CH = CH - CH_(2) - CH_(2) - overset(CN)overset(|)(CH)-]_(n)` (i) On the basis of force between their molecules in a polymer to which class does neoprene belong ? (ii) Can both addition and condensation polymerization result in the formation of a copolymer ? |

Answer» (i) The monomers are : `CH_(2) = CH - CH = CH_(2)` (Buta -1, 3-diene) and `CH_(2) = CHCN` (Acrylonitrile) (ii) Neporene belongs to the class of elastomers since the intermolecular forces present in the monomer units (chloroprene) are quite weak. (iii) Yes, it is in possible. |
