Question

Which among the following polymers is obtained from styrene and 1-3-Butadiene?

• A. Buna-N
• B. PHBV
• C. Butyl rubber
• D. SBR

Hint:

SBR is commonly used for making tires, while other rubbers like butyl and Buna-N have different applications due to their unique properties.

Answer 1

The Correct Option is D

Step 1: Understanding the polymers.
Styrene-butadiene rubber (SBR) is a synthetic rubber made from the copolymerization of styrene and butadiene. It is widely used in the automotive industry, particularly for making tires.

Step 2: Analyzing the options.
(A) Buna-N: This is a copolymer of butadiene and acrylonitrile, not styrene.
(B) PHBV: This is a biopolymer made from 3-hydroxybutyrate and 3-hydroxyvalerate.
(C) Butyl rubber: Butyl rubber is made from isobutene and isoprene, not styrene and butadiene.
(D) SBR: This is the correct option; styrene-butadiene rubber is formed from the copolymerization of styrene and butadiene.

Step 3: Conclusion.
The correct answer is (D) SBR, as it is obtained from styrene and 1-3-butadiene.
