Question

Write the structures of the monomers used for getting the following polymers:
(i) Neoprene
(ii) Melamine-formaldehyde polymer
(iii) Buna-S

Answer 1

(i) Neoprene :
Monomer: Chloroprene `CH_(2) = CH - overset(Cl)overset(|)(C) = CH_(2)`
(ii) Melamine formaldehyde
Monomer :
(i) Formaldehyde : HCHO
(ii)
(iii) Buna-S
Monomer:
(i) Butadiene `H_(2) C = HC - CH - CH_(2)`
(ii)
