Which among the following is a cross-linked polymer?
  1. PVC
  2. Orlon
  3. Vulcanised rubber
  4. Polypropylene

Solution

Vulcanized rubber A cross-linked polymer made by chemically treating rubber with sulfur to create a three-dimensional network of polymer chains. This process is called vulcanization. The cross-links make rubber stiffer and more elastic, and give it mechanical robustness, thermal stability, and chemical resistance.
