Question

Which of the following thermosetting polymers is specifically synthesized by the condensation polymerization of urea ($NH_2CONH_2$) and formaldehyde ($HCHO$), and what is one of its primary commercial applications?

Prashant Kotian · Accepted Answer

Correct answer: C. The condensation of urea and formaldehyde produces urea-formaldehyde resin, a highly cross-linked thermosetting polymer. Due to its rigid 3D structure, it is primarily used in the manufacture of laminated sheets and unbreakable cups.
