The divinyl ether of diallylbisphenol A (VEABA) was investigated as a candidate for advanced composite matrix resin. VEABA was readily prepared in over 90% yield from a condensation reaction between diallyl bisphenol A and chloroethyl vinyl ether using a phase transfer catalyst. Since vinyl ethers are electron-rich monomers, they are polymerized by cationic initiators. The VEABA polymer possesses properties comparable to polymers produced from epoxy resins based on the diglycidyl ether of bisphenol A, except for much lower moisture absorption and a slightly lower glass transition temperature. Since the VEABA monomer is a low viscosity liquid, it is a good candidate for filament winding, resin transfer moulding and pultrusion fabrications for advanced composites.
