Question

Which plastic materials contain strong cross linkages in their molecular structure?
(a) Thermoplastic materials
(b) Thermosetting materials
(c) Both a and b
(d) None of these​

Answer 1

Answer:

Thermosetting materials is the correct answer!!!

Answer 2

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
