    • Metallocene complexes of a metal M selected from titanium, zirconium and hafnium, comprising at least one anionic group A containing an .eta..sup.5 -cyclopentadienyl ring co-ordinated with the metal M, wherein the anionic group is substituted in at least one position of the cyclopentadienyl ring with a radical having the formula:Ph*--(CR.sup.6 R.sup.7).sub.nwherein: R.sup.6 and R.sup.7 are independently hydrogen, halogen or a C.sub.1 -C.sub.4 alkyl group, preferably hydrogen, "n" is 0 or 1, preferably 1, Ph* is a C.sub.6 -C.sub.14 group comprising an aromatic ring linked to --CR.sup.6 R.sup.7 -- or to A and substituted with at least one and up to a maximum of three electron-attractor groups, on the condition that, when A is an .eta..sup.5 -indenyl group and "n" is 0, at least one Ph group is linked to A in position 1 or 3 of indenyl.These complexes can be used in (co)polymerization processes of .alpha.-olefins, possibly in the presence of a suitable co-catalyst, for the production of polyolefins with a very high molecular weight.

    • The invention relates to a chemiluminescent composition, i.e. one which emits light when its various constituent components are mixed together.The composition consists of at least two separate solutions of at least one oxalate, at least one fluorescent substance, hydrogen peroxide and at least one catalyst, in which those components which react together are kept separated. The characteristic of the 9,10-bis(phenylethynyl)anthracene is that the oxalate is a bis(dihalo-acylphenyl)oxalate. This compound is easily and economically produced and is easily soluble in the solvents used, to provide high-intensity light emission for long time periods. The 2,4- or 2,6-acyl substituted phenyloxalate also forms a subject matter of the invention.
    • 本发明涉及一种化学发光组合物,即当其各种组成成分混合在一起时发光的发光组合物。 组合物由至少两种分离的至少一种草酸盐,至少一种荧光物质,过氧化氢和至少一种催化剂组成,其中一起反应的组分被保持分离。 9,10-双(苯基乙炔基)蒽的特征是草酸盐是双(二卤代酰基苯基)草酸盐。 该化合物容易经济地生产,易溶于所用溶剂,长时间提供高强度的发光。 2,4-或2,6-酰基取代的苯甲酸酯也形成本发明的主题。
