ABSTRACT:
Ethylenically unsaturated graftable monomers are prepared by reacting hydroxy substituted orthoesters with electrophilic reagents, an alkaline reagent, and a phase transfer catalyst. Preferably the hydroxy orthoester is 4-hydroxymethyl-2-methoxy-2-methyl-1,3-dioxolane, and the preferred reagent is acryloyl chloride with sodium hydroxide as the base and methyltrialkylammonium (C.sub.8-10) chloride as the phase transfer catalyst.
