Abstract

PURPOSE: To prepare the title resin capable of producing laminates having improved heat and solvent resistance and insulating properties, and excellent blanking properties, by reacting a specific epoxy compound with phenols and formaldehydes.
CONSTITUTION: (A) An epoxy compound having terminal glycidyl etherified groups of formula (R1 and R2 are CH2Cl, CH2Br, or 1W3C alkyl groups; xis 1W5, yand z are 0W3) is reacted with (B) mono-or dihydric phenols, e.g. phenol, 4,4'- dihydroxydiphenylmethane, etc. and (C) formaldehydes, e.g. formalin, hexamethylenetetramine, etc. under heating. The ratio of the epoxy groups to the phenolic hydroxyl groups is preferably about 1:1W8
