Question 15.17:

Write the names and structures of the monomers of the following polymers:

(i) Buna-S (ii) Buna-N
(iii) Dacron (iv) Neoprene

	Polymer	Monomer	Structure of monomer
1.	Buna-S	1, 3-butadiene Styrene	${CH}_{2} = CH - CH = {CH}_{2}$ $C_{6} H_{5} CH = {CH}_{2}$
2.	Buna-N	1, 3-butadiene Acrylonitrile	${CH}_{2} = CH - CH = {CH}_{2}$ ${CH}_{2} = CH - CN$
3.	Neoprene	Chloroprene	$Cl$ $\|$ ${CH}_{2} - C - CH = {CH}_{2}$
4.	Dacron	Ethylene glycol	${HOH}_{2} C - {CH}_{2} OH$
