Abstract
A method is provided for making cationically polymerizable aromatic polypropenylethers and to the aromatic polypropenylethers made thereby. Aromatic polyalkylene glycol prepared from the corresponding polyphenol is reacted with an allylhalide to produce aromatic polyallylether which is thereafter isoemrized to the corresponding cationically polymerizable aromatic polypropenylether.
