Question
Write the classification of polymers based on source. Give examples.###What are natural and synthetic polymers? Give two examples of each type.
✓

Answer

Based on the source polymers are classified as natural, semisynthetic and synthetic polymers.
  1. Natural polymers : These polymers are obtained either from plants or animals, e.g., cellulose, jute, linene, rubber, silk.
  2. Semisynthetic polymers : The fibres obtained by giving special chemical treatment to natural fibres (cellulose) and further regenerated are called semisynthetic polymers e.g., acetate rayon, viscose rayon, cuprammonium silk.
  3. Synthetic polymers : The man made fibres prepared by polymerization of one monomer or copolymerization of
    two or more monomers are called synthetic polymers, e.g., nylon, terylene, polythene, etc.
