Which from following polymers is grouped under elastomers?
- A Buna-S
- B Nylon 6,6
- C Terylene
- D Polythene
Answer & Solution
Correct Answer
(A) Buna-S
Step-by-step Solution
Detailed explanation
Buna-S is a synthetic elastomer, also known as styrene-butadiene rubber (SBR). It has rubber-like properties and can stretch and return to its original shape, making it an elastomer.
Here's a quick breakdown of the other options:
- (B) Nylon 6,6: This is a nylon polymer, a type of polyamide used for fibers and engineering plastics, not an elastomer.
- (C) Terylene: Also known as polyethylene terephthalate (PET), it is a thermoplastic used in fibers and films, not an elastomer.
- (D) Polythene: Also called polyethylene, it's a thermoplastic polymer used in packaging, containers, etc., but not an elastomer.
