Question

Among the following, elastomers are:

• A. Natural rubber
• B. Low sulphur rubber
• C. Buna-S
• D. Butyl rubber

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A Natural rubber
B Low sulphur rubber
C Buna-S
D Butyl rubber

Elastomeric polymers are those polymer chains which are held together by the weakest intermolecular forces. These weak binding forces permit the polymer to be stretched A few 'crosslinks' are introduced and some of that examples are natural rubber, low sulphur rubber, Buna-S, Butyl rubber, Buna-N, neoprene, etc.
