The reaction sequence shown is for Bakelite synthesis, which is a cross-linked polymer. The initial reaction involves the condensation of formaldehyde (HCHO) with phenol, followed by polymerisation under heat. This results in a three-dimensional network, characteristic of Bakelite, which is a cross-linked polymer.
