[Also in Division C3] A polynuclear polyphenol is obtained by condensation under neutral or acidic conditions of at least two moles of a mononuclear phenol with one mole of a dihalide having the structure where each X is halogen, each #SP1/SP is a phenylene group or a substituted derivative thereof wherein one or more of the hydrogen atoms are replaced by monovalent atoms or groups selected from alkyl groups, alkoxy groups and halogen atoms and n is a whole number from 2 to 6. In an example 1,2-diphenoxyethane is reacted with paraformaldehyde and hydrogen chloride to form 1,2 - bis - (p - chloromethylphenoxy)- ethane which is reacted with phenol to form a polynuclear phenol. The products are converted to resoles and the latter converted to foamed resins (see Division C3).
