Abstract
A method is presented to prepare totally functionalized ether-capped oligomeric polyphenols without molecular weight fractionation. The products generally are very low in inorganic salts and are characterized by the absence of volatiles leading to void formation in their subsequent curing. The success of the method rests upon conducting the reaction under totally homogeneous conditions throughout.
