Question

Give the chemical reaction for the preparation of nitrile rubber. Also mention its two properties and two uses.

Answer 1

Hint:. as we know, nitrile rubber is a synthetic rubber so for its preparation we need to react to the copolymers of nitrile rubber, which are 1,4-butadiene and acrylonitrile.

Complete step by step answer:
We have been asked about the preparation of nitrile rubber, its properties and uses.
So, for that:
Nitrile rubber is also known as NBR, Buna-N, and acrylonitrile butadiene rubber, is a synthetic rubber derived from acrylonitrile and butadiene. Trade names include Perbunan, Nipol, Krynac and Europrene. This rubber is unusual in being resistant to oil, fuel, and other chemicals.
Now, for the preparation of nitrile rubber,
We know that Nitrile rubber is also called nitrile-butadiene rubber is an oil-resistant synthetic rubber produced from a copolymer of acrylonitrile and butadiene. Its main applications are in fuel hoses, gaskets, rollers, and other products in which oil resistance is required.

Now, the properties of nitrile rubber,
- It Possesses a high tensile strength $( >10N/m{{m}^ {2}}) $,
- Good resistance to mineral oils, vegetable oils, benzene/petrol, ordinary diluted acids and alkaline.
Now, the uses of nitrile rubber:
- It is used in the manufacturing of disposable non-latex gloves, automotive transmission belts, gaskets, synthetic leather etc.
- It can also be used in the preparation of adhesives and as a pigment binder.

Note: Nitrile gloves are therefore more puncture-resistant than natural rubber gloves, especially if the latter are degraded by exposure to chemicals or ozone. Nitrile rubber is less likely to cause an allergic reaction than natural rubber.
