Document Type and Number:
WIPO Patent Application WO/1997/038024
Kind Code:
A1
Abstract:
A catalyst having a high polymerization activity and capable of providing olefin polymers having a wide molecular weight distribution, which comprises (a) a metallocene compound (a-1) or a titanium catalyst component (a-2) comprising magnesium, titanium, and a halogen as indispensable components, (b) a group 8-10 transition metal compound represented by general formula (I'), and a cocatalyst, wherein M represents Pd, Ni, or Pt; X1 and X2 represent N or P; R1 and R2 represent H or a hydrocarbon radical; R4 and R5 represent a halogen or a hydrocarbon radical; and R6 and R7 represent H or a hydrocarbon radical. An olefin polymer composition which has excellent rigidity and impact resistance is prepared by using a catalyst containing the above transition metal compound (b), and comprises a noncrystalline olefin polymer having an intrinsic viscosity, a glass transition temperature, and a density in respective particular ranges and a conventional olefin polymer other than the above olefin polymer. Another olefin polymer composition which has excellent mechanical properties and heat resistance is prepared by using a catalyst containing the above transition metal compound (b), and comprises a crystalline olefin polymer having an intrinsic viscosity, a melting point, and a density in respective particular ranges and a conventional olefin polymer other than the above olefin polymer.
