An aromatic ether oligomer or polyaromatic ether comprising the formula:
1
wherein Ar is an independently selected divalent aromatic radical; formed by reacting a dihydroxyaromatic with a dihaloaromatic; and wherein the reaction is performed in the presence of a copper compound and cesium carbonate. The polyaromatic ether is formed when neither the dihydroxyaromatic nor the dihaloaromatic is present in an excess amount. The aromatic ether oligomer is formed by using an excess of either dihydroxyaromatic or dihaloaromatic. A phthalonitrile monomer comprising the formula:
2
formed by reacting a 3- or 4-nitrophthalonitrile with a hydroxy-terminated aromatic ether oligomer. A thermoset formed by curing the phthalonitrile monomer. Processes for forming all the above.
一种芳香醚寡聚物或聚芳香醚,包括以下公式:
1
其中Ar是独立选择的二价芳香基团;通过将二羟基芳香与二卤代芳香反应形成;反应在铜化合物和碳酸铯的存在下进行。当二羟基芳香和二卤代芳香均不以过量存在时,形成聚芳香醚。当使用过量的二羟基芳香或二卤代芳香时,形成芳香醚寡聚物。一种酞菁单体,包括以下公式:
2
通过将3-或4-硝基酞菁与羟基终止的芳香醚寡聚物反应形成。通过固化酞菁单体形成热固性物。以上所有的形成过程。
