  Strategic synthesis of model novolac resins

  摘要：

  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.
