Abstract: Syndiotactic polyolefins having a molecular weight distribution Mw/Mn of >/= 3, which may be monomodal, bimodal or multimodal, are obtained by polymerisation or copolymerisation of olefins of the formula RCH=CHR in which a catalyst system comprising an aluminoxane and a transition-metal component (metallocene) is used, where the transition-metal component comprises at least 2 metallocenes of the formula which are stereorigid and whose moiety formed by Zr and the substituents R - R has Cs symmetry or slightly distorted Cs symmetry.

Abstract: A polyolefin film which comprises a polypropylene base layer and at least one top layer of a propylene polymer, wherein the base layer is formed of an isotactic polypropylene and the top layer of a syndiotactic polypropylene, has high sealed-seam strength and excellent optical properties and is useful as, for example, a packaging material.

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.
