Question

Which of the following are highly crossed linked polymers?

• A. Alkyd resin
• B. Melamine
• C. Bakelite
• D. Urea - formaldehyde

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A Alkyd resin
B Melamine
C Bakelite
D Urea - formaldehyde

Cross-linked polymers mean the polymer in which many cross-links are formed between the chains or between monomers.

Bakelite is a condensed cross-linked polymer of formaldehyde and phenol.

Alkyd resin, melamine and urea-formaldehyde are also a cross linked polymer.

Hence, options A, B, C and D are correct.
