Explain the classification of polymers on the basis of origin.

उत्तर
On the basis of the source or origin, polymers are classified into three categories:
- 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: Plant polymer and animal polymers. - 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: fibres, synthetic rubbers, and plastics. - 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.
