Condensation polymerisation of formaldehyde with _____________ does not produce phenolic resin?
Correct answer: D. Melamine
- A. Resorcinol
- B. Phenol
- C. Para-cresol
- D. Melamine
Explanation
Melamine reacts with formaldehyde to form an amino resin, specifically melamine-formaldehyde resin, not a phenolic resin. Phenolic resins require phenol or a phenol derivative such as cresol or resorcinol.
