专利号:US-8981036-B2 优先权日:2012-08-02 标 题:Synthesis of and curing additives for phthalonitriles 发明人:KELLER TEDDY M; LASKOSKI MATTHEW 权利人:KELLER TEDDY M; LASKOSKI MATTHEW; US NAVY 摘要:A composition having a mixture of the below compounds having a mole ratio of at least 1:20. Ar 1 and Ar 2 are independently selected aromatic groups. A composition comprising phthalonitrile compounds that comprise at least 5 mol % of the first compound below. n nA method of: providing a solution of a dichloroaromatic compound having an electron-withdrawing group bound to each aromatic ring containing one of the chloride groups; a dihydroxyaromatic compound or anion thereof; an organic transition metal complex or a transition metal salt; an alkaline hydroxide base; and a solvent; and heating the solution to a temperature at which the dichloroaromatic compound and the dihydroxyaromatic compound react to form a dimetallic salt of an aromatic ether oligomer. The molar ratio of the dihydroxyaromatic compound to the dichloroaromatic compound is greater than 2:1. Water formed during the heating is concurrently distilled from the solution.
