Compositions based on phthalonitrile-terminated polyaryloxy pyridine oligomers, their preparation, their use in the preparation of polyaryloxy pyridine cophthalocyanine lattices and lattices obtained

摘要

we describe polyaryloxypyridine oligomers, compositions obtained by training with terminal phthalonitriles, of a composition of oligomers of polyaryloxypyridine alkali phenolate to terminals from a diphu00e9nolate alkaline and a dihalogu00e9nopyridine, followed by the backlash n on the composition of nitro 4 phthalonitrile.and that may be the average degree of polycondensation of 1 to 50. they can be used in conjunction with a co reagent of benzhydrol derivative containing one or two functional groups in ortho dinitriles, networking, polyaryloxypyridine co polyphtalocyanines.
