Abstract
PURPOSE: To prepare a modified phenolic resin useful for laminated sheets, etc., having internal plasticizing property and excellent low temperature-punchability and heat resistance, by reacting an alkylbisphenol A with formaldehyde in the presence of an alkali catalyst.
CONSTITUTION: (A) An alkylbisphenol A expressed by the formula (R is 6W40C alkyl) is reacted with (B) formaldehyde and, if necessary, (C) a phenolic compound having a benzene ring (e.g. phenol) in the presence of (D) an alkali catalyst, e.g. sodium hydroxide or triethylamine, to give a modified phenolic resin.
