Question

Which of the following polymers contain 1,3-butadiene as one of the monomers?
A . Butyl rubber
B . Nitrile rubber
C . ABS plastic
D . SBR

Answer 1

Structural representation of 1,3-butadiene is shown in the figure .It contains 4 carbon and 6 hydrogen atom.We know that A polymer is composed of many repeating subunits and these subunits are called monomer so we can say that A monomer is a molecule that forms the basic unit for polymers.

Complete step by step answer:

Butyl rubber is a synthetic rubber .It is copolymer of isobutylene with isoprene. It can be made from the monomer isobutylene $\;(C{H_2} = C{(C{H_3})_2})$ only via cationic addition polymerization(It is a method of preparation of polymer).
Nitrile rubber is also known as NBR,Buna-N.This is a family of unsaturated copolymers of 2-propenenitrile and butadiene monomers (1,2-butadiene and 1,3-butadiene).These rubber are more resistant than natural rubber and has superior strength, but has inferior flexibility.
ABS plastic is Acrylonitrile butadiene styrene.It is a thermoplastic polymer. ABS is made up of three monomers: acrylonitrile(A), butadiene(B) and styrene(S). Its properties depend on the ratio of it’s monomers.
SBR or styrene-butadiene rubber is made up of two monomer styrene and butadiene.It is also an synthetic general purpose elastomer that is sometimes used as a substitute for natural rubber.
We got to know that all three polymers Nitrile rubber, ABS plastic ,SBR contain 1,3-butadiene as a monomer. So there are multiple options that are correct.
So, the correct answer is “OptionB,C and D”.

Note: To get the answer of this problem first we need to find out each polymer’s monomer .Here Nitrile rubber, ABS plastic ,SBR contain 1,3-butadiene as monomer while Butyl rubber is polymer of isobutylene with isoprene.In ABS and SBR B stands for butadiene so we can easily recognise its monomer.
