By BYJU'S Exam Prep
Updated on: September 25th, 2023
(a) Terylene
(b) Polystyrene
(c) Bakelite
(d) Neoprene
The polymer which is thermosetting polymer is Bakelite. A polymer that can be irrevocably hardened into the required shape is a thermosetting polymer.
Table of content
Why Bakelite is a Thermosetting Polymer?
- It becomes harder through the curing of a resin, prepolymer, or viscous liquid.
- The process of curing is accelerated by high pressure, mixing with a catalyst, or the application of the right amount of heat or radiation.
- A thermoset cannot be melted for reshaping once it has hardened.
- A thermosetting polymer includes things like polyurethanes, polyurea, bakelite, urea-formaldehyde, etc.
Terylene
- A synthetic polyester fibre is terylene. It is mostly utilised in fabric bags and designer materials.
- It is also referred to as “Dacron.”
- It is created by polymerizing terephthalic acid and ethylene glycol.
Polystyrene
- This synthetic aromatic hydrocarbon polymer is created from the styrene monomer.
- It can be applied to a variety of industries, including refrigeration and food packing.
- Polystyrene comes in the form of thermocol.
- Solid or foamed polystyrene are both possible.
Bakelite
- It results from the condensation of phenol and formaldehyde.
- It is utilised in a variety of products, including electrical insulators, radio and telephone casings, jewellery, kitchenware, pipe stems, children’s toys, and guns.
Neoprene
- It also goes by the name polychloroprene.
- It belongs to a family of synthetic rubbers made by polymerizing chloroprene.
- It is commonly employed in the production of goods like medical and sporting supports.
- Neoprene maintains its elasticity over a broad temperature range and demonstrates strong chemical stability.
Summary:
Which of the following polymer is a thermosetting polymer? (a) Terylene (b) Polystyrene (c) Bakelite (d) Neoprene
Bakelite is a thermosetting polymer. It can be irrevocably hardened into the required shape. The polymer that is obtained by irreversibly hardening viscous liquid prepolymer or a soft solid is called thermosetting polymer.
