उत्तर
Vulcanized rubber is a semisynthetic polymer.
Explanation:
Vulcanized rubber is classified as a semisynthetic polymer, as it is derived from natural rubber that undergoes further chemical modification to create cross-links. This process involves treating natural rubber with sulphur to enhance its physical properties. As a result, the chemical modification of a natural base transforms it into a distinct material.
