The structure of polyurethane formed by the copolymerization of a diol with a diisocyanate is to be drawn. Concept introduction: The polymers (repeating structural units) are derived from the simple and reactive molecules, called as monomers. Depending upon the mode of polymerization , polymerization mainly occurs by addition and condensation polymerization reactions. Copolymerization reactions are defined as the reactions of two different monomers forming a copolymer . Polyurethane is formed by the copolymerization of diol with diisocyanate. To determine: The structure of polyurethane formed by the copolymerization of a diol with a diisocyanate.

Definition Definition Group of atoms that shape the chemical characteristics of a molecule. The behavior of a functional group is uniform in undergoing comparable chemical reactions, regardless of the other constituents of the molecule. Functional groups aid in the classification and anticipation of reactivity of organic molecules.
