  • Patent number: 7034173
    Abstract: The invention relates to chemical products which are suited for use as co-catalysts and which can be obtained by reacting a compound of formula (I), M1R1R2(R3)m with a compound of formula (II), (R4X)q-(G)*(M2R5R6)g. In formula (I), R1, R2 and R3 are the same or different and represent a hydrogen atom, C1–C20 alkyl, C1–C20 alkyl halide, C6–C20 aryl, C6–C20 aryl halide, C7–C40 arylalkyl, C7–C40 arylalkyl halide, C7–C40 alkylaryl or C7–C40 alkylaryl halide; M1 represents an element of the second or third main group of the periodic table of elements, and; m equals 0 or 1, whereby m is equal to 1 when M1 represents an element of the third main group, and m is equal to 0 when M1 represents an element of the second main group.

  • Publication number: 20050239979
    Abstract: A catalyst system includes a metallocene compound having the formula R9 L1 L2 M1R1R2 wherein R9 is a bridge between ligands L1 and L2 and M1 is a metal of Group IVB of the Periodic Table such as titanium, zirconium and hafnium and R1 and R2 can be hydrogen or aliphatic or aromatic groups. Bridge R9 can include silicon, germanium or tin. The metallocene compound of the invention as synthesized has a racemic to meso isomer ratio of greater than 5 to 1, thereby precluding the need for subsequent separation of the meso isomer.

  • Patent number: 6953829
    Abstract: A catalyst system comprising at least one metallocene, at least one cocatalyst, at least one support material and, if desired, further organometallic compounds is described. The catalyst system can advantageously be used for the polymerization of olefins and displays a high catalyst activity and gives a good polymer morphology without it being necessary to use aluminoxanes such as methylaluminoxane (MAO), which usually has to be used in high excess, as cocatalyst.

  • Patent number: 6949614
    Abstract: A catalyst system comprising a metallocene, a cocatalyst, a support material and optionally a further organometallic compound is described. The catalyst system can advantageously be used for the polymerization of olefins. Here, the use of aluminoxanes such as methylaluminoxane (MAO) as cocatalyst is dispensed with and a high catalyst activity and good polymer morphology are nevertheless achieved.
