Verified by Toppr. Correct option is D) Alkyd resins are thermoplastic polyester resins made by heating polyhydric alcohols with polybasic acids or their anhydrides. Glyptal is formed by condensation polymerization of the monomer units ethylene glycol and phthalic acid. Hence, also known as alkyd resin. The correct answer is option D.
