<jats:title>Abstract</jats:title><jats:p>Diphenyl ether‐formaldehyde resin was prepared at 80°C in propionic acid by <jats:italic>p</jats:italic>‐toluenesulfonic acid as catalyst. The mass distribution curve of molecular weight of the resin agreed well with I<jats:sc>MOTO</jats:sc>'s equation.</jats:p><jats:p>From the IR spectrum and elementary analysis of the resin it was concluded that the resin consists of diphenyl ether units, connected by methylene groups, and with H or CH<jats:sub>2</jats:sub>OCOC<jats:sub>2</jats:sub>H<jats:sub>5</jats:sub> as end‐groups.</jats:p>
