Vedclass · Answer

(D) $Novolac$ is a linear polymer formed by the condensation reaction of phenol and formaldehyde in the presence of an acid catalyst.It is used in paints and as a coating material.When $Novolac$ is heated with formaldehyde,it undergoes cross-linking to form an infusible solid mass known as $Bakelite$.Therefore,the statement that $Novolac$ is a cross-linking polymer is incorrect,as it is a linear polymer that forms a cross-linked structure only upon further heating with formaldehyde.

Which of the following statements is incorrect about $Novolac$?
