L. Dulog et P. Bognar, POLYMERIZATION OF ACETYLENES CARRYING PRECURSORS OF AMINYL RADICALS, Macromolecular rapid communications, 16(1), 1995, pp. 43-45
In the search for organic ferromagnets polymers with a conjugated back
bone and pendant persistent radicals are one route of interest. The sy
nthesis of enyl)-2',4',6'-trinitro-2,6-diphenyldiphenylamine] (p-3) an
d enyl)-2',4',6'-trinitro-2.6-diphenyldiphenylamine] (m-3) as precurso
rs of polyradicals are described. A dinuclear rhodium cyclooctadiene c
hloride complex as polymerization catalyst was used to yield polymers
with molecular weights (gel-permeation chromatography) of 100 000 for
m-3 and 210 000 for p-3.
