摘要：NOVELTY - Zirconium containing hetero-aniline polyacetylene resin (I), is claimed. USE - (I) is useful for preparing high temperature resistant polymer, ceramic precursor and anti-ablative material, which is useful in aerospace field. ADVANTAGE - (I) has good storing stability and working performance. DETAILED DESCRIPTION - Zirconium containing hetero-aniline polyacetylene resin of formula (I), is claimed. n = 1-10; and Ar1 = divalent group of formulae (Ia) and (Ib). An INDEPENDENT CLAIM is included for the preparation of (I), comprises (1) mixing ethynyl aniline with an organic solvent according to the ratio of 1:1-8 under the protection of inert gas, at -70 to -60 degrees C, adding butyl lithium and ethynyl aniline in the ratio of 1:1.5-2.5 for 1-4 hours, standing for 4-6 hours, reacting the lithium bis ethynyl aniline with (Ia) and (Ib), (2) adding tetrahydrofuran solution and zirconium tetrachloride solution with the lithium bis ethynyl aniline in the ratio of 1:1-2 to react at -10 to 0 degrees C for 1-2 hours and then refluxing at 55-60 degrees C for 4-6 hours, standing for 12-14 hours at room temperature, and (3) filtering the obtained product and then carrying out filtrate rotary evaporation.
