Question

A three-dimensional network polymer is formed by monomers which are ______.

विकल्प

• monofunctional

• bifunctional

• polyfunctional

• none of these

Answer 1

A three-dimensional network polymer is formed by monomers which are polyfunctional.

Explanation:

Three-dimensional network polymers are formed from polyfunctional monomers, which have more than two reactive functional groups. These monomers form cross-links in different directions, producing a rigid network structure. Examples include Bakelite and melamine-formaldehyde resin.
