    Abstract: The present invention is a method of making cross-linked or cross-linkable polyarylenes comprising providing a reaction mixture comprising (a) a first monomer comprising at least two cyclic functional groups (b) a second monomer comprising at least two dienophile functional groups, and heating the reaction mixture to form a polymerized or partially polymerized polyarylene material, wherein at least one of the first or second monomers must comprise at least three functional groups. The cyclic groups in the first monomer are characterized by the presence of two conjugated carbon to carbon double bonds and a leaving group, L, selected from -0-, —S—, —(SO2)—, —N═N—, or —O(CO)—. The present invention is also the partially polymerized reaction product of the above method. Finally, the present invention is also specific difunctional diene monomers useful in such a method.

    Abstract translation: 本发明是一种制备交联或可交联聚芳烯的方法,其包括提供反应混合物,其包含(a)包含至少两个环状官能团的第一单体(b)包含至少两个亲双烯体官能团的第二单体,和 加热反应混合物以形成聚合或部分聚合的聚亚芳基材料,其中第一或第二单体中的至少一种必须包含至少三个官能团。 第一单体中的环状基团的特征在于存在两个共轭碳 - 碳双键,离去基团L选自-O-,-S-, -​​ (SO 2 - ) - ,-NN-或-O(CO) - 。 本发明也是上述方法的部分聚合反应产物。 最后,本发明也是在这种方法中有用的特定的双官能二烯单体。
