Abstract

The present invention provides a process for producing monohydroxy polyallyl ethers by reacting a polyol with allyl halide in an alkaline reaction medium until about 50-80 mol % of the allyl halide to be reacted, has reacted, then adding excess solid alkali metal hydroxide in a single addition to the reaction medium. The addition of the solid alkali metal hydroxide to the reaction medium creates a reaction medium having a substantially constant free hydroxy ion concentration in the aqueous phase allowing the monohydroxy polyallyl ether to be formed in high yields.
