a)
Interpretation: The monomers of Kevlar with the structure of Nomex polymer are to be drawn and the differences in their structures are to be stated.
Concept introduction: Polymer is defined as a substance made up of large number of units bonded together. A single unit is known as monomer.
To determine: The monomers of Kevlar polymer.
(b)
Interpretation: The monomers of Kevlar with the structure of Nomex polymer are to be drawn and the differences in their structures are to be stated.
Concept introduction: Polymer is defined as a substance made up of large number of units bonded together. A single unit is known as monomer. Polymers are formed mainly by two types of reactions namely, addition reactions and condensation polymerization reactions. The condensation polymerization reactions are defined as the reaction in which two or more monomers combine together to form a single molecule with an elimination of small molecules like water.
To determine: The structure of Nomex polymer and the differences in the structures of Kevlar and Nomex polymer.
