Abstract: The present disclosure provides a polymerizable composition. The polymerizable composition includes a phthalonitrile resin, a curative, and a polyoxometalate of Formula I: Hn[XM12O40] (I). In Formula (I), M is W or Mo, n is 1 to 6, and X is a heteroatom selected from P, Si, S, Ge, As, Te, or Se. The present disclosure also provides an article. The article includes a polymerization product of the polymerizable composition. Additionally, a method is provided. The method includes mixing a polyoxometalate of Formula I with at least one of a curative or phthalonitrile resin and mixing at least a portion of the curative with at least a portion of the phthalonitrile, thereby forming a polymerizable composition. The method further comprises subjecting the polymerizable composition to a temperature of 180° C. to 250° C., to form an at least partially polymerized article and subjecting the at least partially polymerized article to a temperature of 300° C. to 350° C. to complete polymerization of the article.
