Question

Answer the following.

What are synthetic resins? Name some natural and synthetic resins.

Short Note

Solution

  • Synthetic resins:

These polymers are artificially prepared by polymerization of one monomer or copolymerization of two or more monomers.
e.g. nylon and terylene.
Synthetic polymers are further divided into three subtypes: fibres, synthetic rubbers, and plastics.

  • Natural resins: Natural rubber, silk, wool, etc.
  • Synthetic resins: Nylon, terylene, neoprene, etc.
