A curable composition includes a functionalized poly(arylene ether), an alkenyl aromatic monomer, an acryloyl monomer, and a polymeric additive from polystyrene, poly(styren-maleic anhydride), poly(styrene-methyl methacrylate), polybutene, poly(ethylene-butylene), poly(vinyl ether), poly(vinyl acetate), and combinations thereof. Curable compositions comprising polybutene having a number average molecular weight of greater than or equal to 300 atomic mass units form sol-gels having sol-gel transition temperatures of greater than about 60°C. These sol-gel compositions also exhibit lower tack at ambient temperature.
