Strategic synthesis of model novolac resins

Model novolac resins which contain the maximum number of free ortho positions for reaction with the curing agent hexamethylenetetramine (HMTA) have been prepared. The key transformation was the ion assisted ortho-specific phenol-formaldehyde oligomerization of suitably protected precursors.

The chemistry of novolac resins. Part 4. The strategic synthesis of model compounds.

An ion assisted ortho-specific phenol-formaldehyde condensation process, incorporating selective protecting-deprotecting methodology has been adapted to prepare a range of model novolac compounds which are ideal for studying crosslinking with hexamethylenetetramine.
