What is the glass transition temperature of polybutadiene?

(a) -100 F

(b) -25 F

(c) 125 F

(d) 300 F

This question was posed to me in an online interview.

My question comes from Types of Rubbers in chapter Glass & Elastomers of Engineering Material & Metallurgy

The correct choice is (a) -100 F

To explain I would say: Polybutadiene elastomers are known for their low-temperature performance. They have the lowest brittle or glass transition temperature after silicones. These elastomers possess excellent resilience and abrasion resistance.
