Title:
CATALYST FOR POLYMERISATION OF STYRENE AND DIENES, PREPARATION METHOD THEREOF AND USE OF SAME
Document Type and Number:
WIPO Patent Application WO2004007602
Kind Code:
A3
Abstract:
The invention relates to a catalyst for the polymerisation of 1,4-dienes, styrene and for the copolymerisation of two monomers. The characteristics of the inventive catalyst include a high degree of stereoselectivity, catalytic activity and tolerance to the presence of polar impurities. Said catalyst combines the characteristics specific to Ni-based diene polymerisation catalysts (high stereoselectivity and catalytic activity) with a well-defined character and tolerance to the presence of polar substances. The inventive preparation method is simple, thereby facilitating the practical use thereof.
