ABSTRACT - 594213 Disclosed herein is polymer comprising -[MN2]- as a repeating unit, wherein M is selected from the group consisting of Ti, V, Cr, , Zr, Nb, Mo, and mixtures thereof. A method of producing a polymer is also disclosed which comprises: (i) reacting M with R to produce compounds selected from the group consisting of MR3, MR4, and mixtures thereof, wherein M is selected from the group consisting Ti, V, Cr, Zr, Nb, Mo, and mixtures thereof, and R is a sterically demanding group or a group that protects a low coordination number for M; and (ii) reacting the compounds selected from the group consisting of MR3, MR4, and mixtures thereof with hydrazine in an inert atmosphere to produce a polymer comprising repeating units selected from the group consisting of -[MN2]-, -[M2N3]-, and mixtures thereof, and wherein the steps of reacting the compounds selected from the group consisting of MR3, MR4, and mixtures thereof with hydrazine is carried out in the presence of a solvent. |
