Which of the following is NOT a natural polymer?

Options

  1. AProtein
  2. BStarch
  3. CRubber
  4. DRayon

Correct answer

D. Rayon

Step-by-step solution

Natural polymers These polymers are found in plants and animals. Examples are proteins, cellulose, starch, some resins and rubber. Semi synthetic polymers are those polymers that are prepared by chemically treating natural polymers. Rayon is a regenerated cellulosic fibre. So, Rayon is semisynthetic polymer.
