Polyester resins are the product of reaction between
Correct answer: A. Dihydric alcohol and dicarboxylic aromatic acids
- A. Dihydric alcohol and dicarboxylic aromatic acids
- B. Polyamines with aliphatic dicarboxylic acids
- C. Styrene in the presence of catalyst
- D. Epichlorohydrin with diphenylolpropane
Explanation
The correct answer is Option A: Polyester resins are synthesized by the polycondensation of dihydric alcohols and dicarboxylic aromatic acids. This process creates the ester linkages characteristic of polyesters. Option B is incorrect as it describes the formation of polyamides, not polyesters. Option C is incorrect because styrene is associated with the production of polystyrene, not polyester. Option D is incorrect as it describes the formation of epoxy resins, not polyester resins.

About Industrial Chemistry
Industrial chemistry applies chemical reactions and material properties to the manufacture of adhesives, dyes and polymers. Coverage includes addition and condensation polymerisation, thermoplastics and thermosetting polymers, the structural basis of colour in dyes, and how adhesive composition enables bonding between surfaces.
