    摘要： Unsaturated polyol compounds containing alkenyl aryl constituents are described. These unsaturated polyols are prepared by reacting a polyol with an aromatic derivative including both an alkenyl constituent and a second functionality reactive with a polyol. The resulting unsaturated polyols feature an alkenyl aryl constituent which enhances polyol receptivity for graft copolymerization with vinyl monomers. The aryl constituent along with multiple hydroxyl groups of the polyol render these polyols particularly suitable for polyurethane end uses.
