Abstract: The preparation of indenes of formulae (I) and (IA) comprises: (a) reacting a di-substituted benzene of formula (II) with a carbonyl compound (or anhydride) of formula (III) to give indanones of formulae (IV) and (IVA); and (b) reducing to the corresponding indanols and dehydrating; R = H, halogen, 1-10C optionally halo-substituted alkyl, 6-10C optionally halo-substituted aryl; -NR2 , -SR , -OSiR3 , -SiR3 or -PR2 ; R = halogen, 1-10C alkyl or 6-10C aryl; R -R = as for R but not H; and X , X = nucleophilic leaving groups. Also claimed are: (i) indenes of formula (I) and (IA); (ii) use of indenes (I) and (IA) in the preparation of metallocene of formula (V); (iii) novel indanones (IV) and (IVA); and (iv) use of indanone for prepn. of indenes.

Abstract: of the disclosure Polyolefin molding composition having a broad melting range, process for its preparation, and its use Polyolefin molding compositions which have a broad, bimodal or multimodal melting range in the DSC spectrum, where the melting range maximum is between 120 and 165.degree.C, are obtained by polymerization or copolymerization of at least two olefins to give polyolefins of different melting point. The olefins have the formula RaCH=CHRb, and the catalyst system comprises an aluminoxane and at least two transition-metal components of the formula I (I) in which M1 is Zr, Hf or Ti.

Abstract: A polyolefin moulding composition essentially comprising a) a polyolefin wax b) a high-molecular-weight polyolefin or, instead of b), c) a high-molecular-weight olefin copolymer is distinguished by high rigidity and hardness. In order to increase the impact strength, a rubber having a glass transition temperature of below -20 DEG C may additionally be admixed with this moulding composition.
