NCERT Solutions for Class 12 Chemistry Chapter 15 Polymers


Polymers are macromolecules formed by the chemical bonding of large numbers of smaller molecules, or repeating units, called monomers. The point at which monomers or prepolymers combine to a sufficient degree in a single molecule to be specifically called a polymer is largely arbitrary. Chemistry Chapter 15 includes topics like – the terms Monomer, Polymer, Polymerisation. Classification of Polymers based on source: Natural polymers, Semi-synthetic polymers, Synthetic polymers. Category of polymers based on structure: Linear Branched-chain, Cross-linked or Network Polymers. Classification of polymers based on the mode of polymerization: Addition polymers, Condensation polymers.
