ABSTRACT:
Oligomer compositions of polyaryloxypyridine with acetylenic end groups are btained by formation of an oligomer composition of polyaryloxypyridine with halogenated end groups from an alkaline diphenolate and a dihalogenopyridine, followed with an ethynylation reaction. The average polycondensation degree may range from 1 to 50. Theses compositions can be used to form cross-linked lattices by polyaddition of the ethynyl groups.
