A HIGHLY CONJUGATED POLYMER FROM TETRAPROPARGYLAMMONIUM BROMIDE

A highly conjugated polymer was synthesized by the polymerization of m ultiacetylenic compound, tetrapropargylammonium bromide (TPAB), with v arious transition metal catalysts in high yields. PdCl2, PtCl2, RuCl3, MoCl5-EtAlCl(2), and WCl6-EtAlCl(2) were found to be effective for th e polymerization of TPAB. Various possible polymer structures were sug gested for poly(TPAB) via different cyclopolymerization pathways of te trapropargyl functional groups. The resulting polymers were insoluble in organic solvents, and black or brown powder.
