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.
