Answer:

The answer is option (b)Thermosetting materials

Explanation:

A thermosetting polymer, commonly known as a thermoset, is a polymer made up of crosslinked structures or molecules with a lot of branches.

  • On heating, these polymers that are in a soft solid or viscous state undergo substantial cross-linking processes, resulting in irreversibly hard and insoluble products.
  • Thermosetting plastics may be molded and pressed into shapes once heated. They can't be warmed once they've been set since they're permanently set.
  • Thermosetting plastics are synthesized by condensation polymerization and they are high in molecular weight

Examples are bakelite, urea-formaldehyde, and melamine formaldehyde
