Constructing Polymers Using the LEGO Principles

In this section I will limit myself to the LEGO principles for construction of polymers from their building blocks. To make matters clear, let me state at the outset that our principle is a reverse construction of a giant molecule, with an aim of conceptualizing it. We are not describing the actual chemical mechanisms whereby these molecules are made, although the resemblance is there.

FIGURE 6.4 Three polymers formed by condensation (these can be constructed using the clack-click approach) (a) Dialkylsilicone. (b) Polyester, (c) Nylon. The latter two are copolymers including two different monomers.
