Question
The synthesis of several important industrial resins relies on the high reactivity of formaldehyde ($HCHO$) as a cross-linking agent. Which of the following commercial polymers require formaldehyde as an essential monomeric precursor?
Answer: A,B,C
💡 Solution & Explanation
Bakelite and its linear prepolymer Novolac are synthesized from phenol and formaldehyde. Melamine-formaldehyde resin is synthesized from melamine and formaldehyde. Glyptal, however, is a polyester synthesized from ethylene glycol and phthalic acid, and does not require formaldehyde.
