Question

How are polymers classified on the basis of the source of availability?

Answer 1

1. Natural polymers: The polymers obtained from natural source are said to be natural polymers.
   e.g. cotton and linen.
   Natural polymers are further subdivided into two types such as plant polymer and animal polymers.
2. Synthetic polymers: 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 such as fibres, synthetic rubbers, and plastics.
3. Semisynthetic polymers: Polymers which are derived from natural polymers are called semisynthetic polymers. These are also called regenerated fibres.
   e.g. cellulose acetate, rayon, and cellulose nitrate.
