Identify the monomers used for preparation of glyptal?

Step-by-step solution

Glyptal is a condensation polymer belonging to the class of polyesters. It is synthesized by the condensation polymerization of ethylene glycol (ethane-1,2-diol) and phthalic acid (benzene-1,2-dicarboxylic acid). The polymerization reaction involves the elimination of water molecules to form ester linkages between the monomers. Answer: Ethylene glycol and phthalic acid
