____________ of SBR is adversely affected, if more quantity of styrene is added to butadiene during its co-polymerisation to produce SBR?
Correct answer: D. Resilience
- A. Percent elongation
- B. Strength
- C. Freezing point
- D. Resilience
Explanation
Increasing the styrene content of SBR makes it harder and stronger but reduces its resilience, or ability to recover after deformation. This loss of elastic recovery is the key effect tested here.
