Condensation or Step-Reaction
Polymerization
In condensation polymerization, condensation takes place between two
polyfunctional molecules to produce one larger polyfunctional molecule,
with the possible elimination of a small molecule such as water. The
reaction continues until almost all of one of the reagents is used up; an
equilibrium is established which can be shifted at will at high
temperatures by controlling the amounts of the reactants and products.
Two types of condensation polymers are:
Polyamide (nylon)
Polyester
