Terminated bis(3,4-dicyanophenoxy) alkanes, wherein the alkylene chain is om 2 to 30 carbon atoms in length, is prepared by the reaction of 4-nitrophthalonitrile with a terminated alkane diol at elevated temperatures. A polyphthalocyanine resin is obtained by heating the dicyanophenoxy alkanes neat or with a salt or metal at a temperature from about 180.degree. C. to about 245.degree. C. The polyphthalocyanine resin is useful as a high-temperature structural or composite material which is highly resistant to mechanical stresses and strains.
终止的双(3,4-二氰基苯氧基)烷烃,其中烷基链长度为2到30个碳原子,是通过在高温下将4-硝基邻苯二腈与终止的烷基二醇反应制备的。通过在约180摄氏度至约245摄氏度的温度下加热这些二氰基苯氧基烷烃,可获得聚邻苯二腈树脂。这种聚邻苯二腈树脂可用作高温结构或复合材料,具有高度抗机械应力和应变的特性。
