The compound HOCH2-N(-CH2OH)-C(=O)-N(-CH2OH)-CH2OH undergoes condensation polymerisation to form which type of polymer?

1. Urea-formaldehyde resin
2. Phenol formaldehyde resin
3. Alkyd resin
4. Melamine-formaldehyde resin

Correct answer: Urea-formaldehyde resin

Solution

The compound shown is a methylolated urea (dimethylolurea with additional CH2OH groups), which is the key intermediate in urea-formaldehyde resin synthesis. Condensation of these -CH2OH groups with -NH- groups or other -CH2OH groups forms the crosslinked thermoset urea-formaldehyde resin.
