Polymers Class 12 Notes

Polymer

The polymers are defined as high molecular mass macromolecules which consists of repeating structural units derived from appropriate monomers. The process of formation of polymers from the respective monomers is called polymerization.

Classification of polymer on the basis of source

  • Natural polymer
  • Semi-synthetic polymer
  • Synthetic polymer

Classification based on structure

  • Linear polymer
  • Branched chain polymer
  • Cross linked polymer

Classification based on the mode of polymerization

  • Addition polymer
  • Condensation polymer

Classification based on molecular force

  • Fibres
  • Elastomers
  • Thermosetting plastics
  • Thermoplastics

Examples of important polymers

  • Natural Rubber
  • Synthetic rubber
  • Buna rubbers
  • Buna -S
  • Teflon
  • Nylon -66
  • Dacron
