Question

Write the reaction to prepare navolac polymers

Answer 1

Answer:

The monomers used in the preparation of novolac polymer are phenol and formaldehyde. They undergo polymerisation in presence of alkali or acid as catalyst. Phenol reacts with formaldehyde to form ortho or p-hydroxy methyl phenols, which on further reaction with phenol form a linear polymer called Novolac.
