Question

A polymer of butadiene and Acrylonitrile is called, a) Buna-S
b) Buna-N
c) Buna-B
d) Buna-A

Answer 1

Polymer of Butadiene and Acrylonitrile is called BuNa-N

Answer 2

Nitrile has also rubber known as NBR and acrylonitrile rubber and includes synthetic ability and withstand for range of temperatures from -40 to 108 degree that has ideal material for aeronautical applications.

It includes nitrile and reason for grabbing butadiene rubber that synthetic rubbers.

This should form based on butadiene and Na for sodium and used for moderate temperature.
