Question

Which from following is a thermoplastic polymer?

• A. Terylene
• B. Neoprene
• C. Polythene
• D. Bakelite

Hint:

Thermoplastics soften on heating and harden on cooling, like polythene.

Answer 1

The Correct Option is C

Step 1: Elimination
Bakelite is cross-linked and thermosetting. Neoprene is a synthetic rubber, so it is classified as an elastomer.

Step 2: Remaining
Polythene is the classic example of a thermoplastic in the syllabus, so it is the intended answer, option (C).

Final Answer:
Polythene is the thermoplastic. \[ \boxed{\text{(C) }\text{Polythene}} \]
