______________are produced by reacting polybasic acid (e.g. Phthalic anhydride) with polyhydric alcohol (e.g., glycerol) ?
Correct answer: B. Alkyd resins
- A. Unsaturated polyester
- B. Alkyd resins
- C. Saturated polyester
- D. Amino resins
Explanation
Alkyd resins are formed by reacting a polybasic acid or anhydride such as phthalic anhydride with a polyhydric alcohol such as glycerol. Their ester structure distinguishes them from amino resins.
