Abstract
A new process for producing allyl ethers, usually C.sub.8-30 alkyl (CH.sub.2 CH.sub.2 O).sub.5-100 allyl ether, by forming a solution of an alcohol, usually a surfactant alcohol, in a solvent capable of forming an azeotrope with water, azeotroping the mixture to remove substantially all the water, adding an alkalimetal alkoxide, usually sodium methoxide, removing the alkanol formed, usually by azeotroping with the solvent, adding a halide, usually allyl chloride, and recovering the allyl ether. The ethers are useful as monomers, for example to produce polymers by copolymerising with copolymerisable ethylenically unsaturated comonomers for a wide range of applications.
