    摘要: Novel polymers consisting essentially of frecurring moieties selected from polyquinoxaline and substituted polyquinoxalines are disclosed. These polymers are prepared by contacting 1,2,3,4-tetrahydroquinoxaline or 1,2,3,4-organo substituted tetrahydroquinoxaline compounds with a transition metal sulfide catalyst at elevated temperatures. Also disclosed are quaternary ammonium derivatives of the novel polymers, their preparation and use.

    摘要: The present invention is predicated on the discovery that quinoline and substituted quinoline derivatives, having substituents in positions other than the 2 and 6 position, undergo polymerization in the presence of tetrahydroquinoline or substituted tetrahydroquinolines and a transition metal sulfide catalyst to produce polymers that have repeating quinoline and substituted moieties.Thus, in one embodiment of the present invention, there is provided a novel method of preparing polymers having the formula ##STR1## which comprises contacting a tetrahydroquinoline having the formula ##STR2## with a quinoline compound having the formula ##STR3## at elevated temperatures and in the presence of a transition metal sulfide catalyst wherein the metal is selected from Groups VIB, VIIB of the periodic table and mixtures thereof and wherein the Rs (i.e. R.sub.3, R.sub.4, etc.) and the R's (i.e. R'.sub.3, R'.sub.4, etc.) may be the same or different and are selected from hydrogen, halogen (especially fluoro-, chloro- and bromo-), --NO.sub.2, OH, --NH.sub.2, --SH, --CN and organic substituents. In the above polymer, x and y represent the relative proportion of bracketed structural quinoline or substituted moieties, and n is an integer equal to or greater than 2.
