摘要:
The present invention relates to a catalyst composition for homopolymerization or copolymerization of olefins comprising: (a) a solid catalyst precursor comprising a transition metal compound of group IVB, VB, or VIB of the periodic table, a magnesium compound and aliphatic polyketone particles; and (b) a cocatalyst comprising an aluminum alkyl, an aluminoxane or mixtures thereof; and a process for homopolymerisation or copolymerisation of olefins.
摘要:
Supported catalyst composition for polymerization of olefins comprising: (i) a titanium compound, a magnesium compound and at least one electron donor compound; (ii) an oxygen containing polymer support; and (iii) a cocatalyst comprising at least one aluminum compound.
