摘要：
The disclosed compositions of polyaryloxypyridine oligomers with phthalonile end groups are obtained by formation of a composition of polyaryloxypyridine oligomers with alkali phenolate end groups, followed with the reaction of said composition with 4-nitrophthalonitrile. Their average polycondensation degree may range from 1 to 50. They can be used in combination with a co-reactant derived from benzhydrol and containing one or two ortho-dinitrile functional groups, to constitute polyaryloxypyridine co-polyphthalocyanine lattices.
