- thermoplastic, thermosetting
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
• Polystyrene $\longrightarrow$ formed by addition polymerization $\longrightarrow$ chain growth
• Dacron (polyester) $\longrightarrow$ formed by condensation $\longrightarrow$ step growth
Step 1: Polystyrene.
Addition polymer $\longrightarrow$ chain growth
Step 2: Dacron.
Condensation polymer $\longrightarrow$ step growth
Step 3: Final answer.
Chain growth, Step growth
