ABSTRACT:
A process for preparing a substituted styrene by reacting a bisarylalkyl ether in the presence of an acid catalyst is disclosed. The process is preferably used for the preparation of 4-acetoxystyrene from 4,4'-(oxydiethylidene)bisphenol diacetate and 4-methoxystyrene from 4,4'-(oxydiethylidene)bisphenol dimethyl ether. A process for preparing a bisarylalkyl ether by reacting a corresponding arylalkanol in the presence of an acid catalyst is also disclosed.
