Definitions
- the present invention relates to a process for the homogeneous catalytic preparation of highly branched amorphous polyolefins with an elastomeric property profile based on ethene.
- branched polyolefins can also be obtained from ethene if two metallocene complexes are combined with one another.
- this is only possible if the polymerization activity of the transition metal compounds used towards ethene is very well coordinated, because otherwise either no polyolefin backbone or no 1-alkenes to be polymerized are formed.
- care must also be taken to ensure that the transition metal compounds used do not give dimeric coupling products from the 5 1-alkenes produced, which would lead to inhomogeneous product mixtures.
- the two metallocene compounds, which are different in their reactivity must not have any chemical interaction with one another.
- Triethyl aluminum had to be reduced, and then the reaction after the addition of a Ziegler / Natta compound, e.g. Titanium tetrachloride vanadium oxide trichloride, continued.
- a Ziegler / Natta compound e.g. Titanium tetrachloride vanadium oxide trichloride
- a catalyst composition consisting of a polymerization catalyst based on an early transition metal compound and a polymerization catalyst based on a late transition metal compound is described in DE-A 197 07 236.
- Ziegler / Natta catalysts for example based on titanium tetrachloride or metallocene catalysts, are used as early transition metal compounds based on titanium, zirconium or hafnium cyclopentadienyl complexes, used as late transition metal compounds, for example diimine complexes of nickel or palladium.
- the polymer blends obtained contain linear or only slightly branched polyethylene in addition to branched polyethylene.
- EP-A 0 250 999 discloses the combined use of a nickel-ylide complex as an oligomerization catalyst with a heterogeneous chromium polymerization catalyst supported on silica gel for the production of branched polyolefins starting from ethene. In this way, however, only polyolefins with very long alkyl branches are obtained, which is why materials with a partially crystalline or crystalline, but not with an amorphous property profile are obtained.
- WO 99/10391 describes simultaneous and sequential
- branched polyolefins from, for example, ethylenetridentate
- iron bisimine complex compounds and metallocene catalysts are added to the reaction mixture either simultaneously or sequentially.
- branched polyolefins with sufficiently high alkyl branching rates and suitable alkyl branching patterns which likewise have a sufficiently elastomeric property profile, can not be reproducibly achieved by the process described, in order to be able to be used as toughness modifiers. This is already contradicted by the thermal properties of the polymers described, which have melting points T m > 100 ° C.
- the present invention was therefore based on the object of making available a process with which amorphous or largely amorphous elastomeric polyolefins can be obtained in a preparative, simple and efficient manner, even on an industrial scale, in a satisfactory manner.
