摘要：
A process for producing a polyglycidyl ether which comprises reacting a mixture of 4-oxy-3-methoxybenzaldehyde and 4-oxybenzaldehyde in the molar ratio of 5/95 to 95/5 with pentaerythritol to give a bisphenol having a spiroacetal ring, and further reacting the bisphenol with epihalohydrin or .beta.-methylepihalohydrin is disclosed. The polyglycidyl ether obtained has excellent solubility in solvents, and the cured product obtained therefrom has excellent elongation, modulus of elasticity, impact resistance, and heat resistance.
