摘要：

High molecular weight aromatic polyformals free of macrocyclic oligomers were synthesized using condensative chain polymerization reaction. The reaction of bisphenol with methylene bromide in the presence of potassium hydroxide in a solvent like N-methylpyrrolidinone was carried out under high-intensity mixing conditions at about 100° centigrade. The process could be used for the synthesis of corresponding polythioformals from dithiols.
