The structure of the polymer formed by condensation of glycerol and phthalic acid is to be drawn and the cross linking that occurs in this polymer is to be explained. 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. Cross link is defined as a bond that link one polymer chain to another polymer chain. When the polymer chains are cross linked with each other they lose their tendency to move individually. To determine: The structure of the polymer formed by condensation of glycerol and phthalic acid and the cross linking that occurs in this polymer is to be explained.

Solution Summary: The author explains the structure of the polymer formed by condensation of glycerol and phthalic acid and the cross linking that occurs in it.
Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
