Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Thermoplastic materials can be crystallizable or non-crystallizable.
The structure affects their properties.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the properties of thermoplastics.
Step 3: Detailed Explanation:
Polystyrene is non-crystallizable and has bulky pendent groups (phenyl groups).
PET, HDPE, and LLDPE are crystallizable or semi-crystalline.
Thus, polystyrene is the correct answer.
Step 4: Final Answer:
Polystyrene is non-crystallizable with bulky pendent groups.
Hence, the correct option is (C).
