摘要： Described herein are fluoropolymer compositions comprising a compound of Formula I wherein X1 is selected from O or S; L is a divalent linking group comprising at least one aromatic ring; and X2 is selected from the group consisting of a hydroxyl group, an amino group, a thiol group, and a nitrile group. In one embodiment, the phthalonitrile-containing compound is used to crosslink a dehydrohalogenated polymer, and optionally with a polyhydroxy curative. In another embodiment, the phthalonitrile-containing compound is added to a composition comprising (i) a fluorinated elastomeric gum, wherein the fluorinated elastomeric gum comprises a fluoropolymer having a cure-site and (ii) a peroxide curing system.

摘要： The present disclosure provides a resin blend containing a blend of a first phthalonitrile resin, a filler, and a bisphenol M diphthalonitrile ether resin. Suitable fillers include at least one of nanoparticles, microparticles, or fibers. The present disclosure also provides an article including a polymerization product of such a resin blend. The resin blends can be prepared at lower temperatures than phthalonitrile resin blends without a bisphenol M diphthalonitrile ether resin.

摘要： 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.
