    Abstract: Prodn. of carbon-bridged biscyclopentadiene cpd. comprises reacting one or two cyclopentadiene cpds. (LH), at least one being a substd. cyclopentadiene, with a carbonyl cpd. in the presence of a base and a phase transfer catalyst. Also claimed is the prodn. of a phase transfer catalyst. Also claimed is the prodn. of a carbon-bridged biscyclopentadienyl-metallocene.

    Abstract: Stereo-rigid metallocene cpds. contain, as ligands: (i) substd. or unsubstituted cyclopentadienyl gps. linked together by a 5-membered ring condensed with the cyclopentadienyl gp(s)., where: (1) the ligand system is other than 4-Ä eta -3'-alkyl-cyclopentadienyl)-4,6,6-trimethyl-( eta -2-alkyl- 4,5-tetrahydro-pentalene)Ü. Also claimed are: (i) a catalyst contg. stereo-rigid metallocene and cocatalyst(s); (ii) a process for the prodn. of polyolefins by polymerisation of olefins in presence of the catalyst; (iii) use of the stereo-rigid metallocene cpd. for olefin polymerisation; and (iv) polyolefin obtd. by the process.

    Abstract: A metallocene cpd. of formula (I) is new: In (I), M = Gp. IVb, Vb or VIb metal; R , R = H, 1-10C alkyl or alkoxy, 6-10C aryl or aryloxy, 2-10C alkenyl, 7-40C aralkyl, 8-40C aralkenyl, OH or halogen; R -R = H, halogen, opt. halogenated 1-20C hydrocarbyl, -NR2, -SR, -OR, -OSiR3, -SiR3 or -PR2 (with R = halogen, 1-10C alkyl or 6-10C aryl); or two or more of these gps. may form a ring system with the attached atoms; and R '-R ' = as for R -R . Also claimed are: (i) olefin polymerisation catalysts contg. cpd(s). (I) and a co-catalyst; and (ii) a process for the prodn. of olefin polymers by (co)polymerisation of olefins in the presence of (I) and a co-catalyst.
