- D. thermosetting polymer
Answer
A. elastomer
Step-by-step solution
Buna-S is a synthetic rubber formed by the copolymerization of 1,3-butadiene and styrene. Since it is a rubber, it possesses elastic properties and is classified as an elastomer. The intermolecular forces in elastomers are weak van der Waals forces, which allow the polymer chains to be stretched. Answer: elastomer
