Title:
CATALYST COMBINATION, ISOTACTIC POLYMERS, METHOD FOR PRODUCING LINEAR ISOTACTIC POLYMERS, AND THE USE OF SAID POLYMERS
Document Type and Number:
WIPO Patent Application WO2004067581
Kind Code:
A3
Abstract:
The invention relates to a catalyst combination which is used to produce linear isotactic polymers and contains an activator and an asymmetric metal complex according to formula I, wherein R<6>-R<9> represents hydrogen, linear or branched C1-C10 alkyl, five-membered to seven-membered cycloalkyl that can carry a plurality of C1-C6 alkyl radicals as substituents, and C6-C18 aryl, arylalkyl or alkylaryl, with the proviso that the radicals R<6>/R<7> or R<8>/R<9> are bound into five-membered to seven-membered fused cycloalkyl or aryl rings that can be substituted, interrupted by heteroatoms and/or linked to another cycloalkyl and/or aryl ring.
