The substituent in the 2-position of one indenyl ligand can be any radical comprising hydrogen, methyl, or any other C2-C40 hydrocarbon which is not branched in the? Examples 10 to 15 include a relatively high melting point polymer component and a relatively low melting point polymer component and illustrate polymer blends according to the invention.
The polymerization can be carried out in one or more stages, in a known manner in bulk, in suspension or in the gas phase, in reactors usually used for polymerizing propylene.

The composition of claim 13 wherein said xylene soluble fraction has an intrinsic viscosity of above about 2. The metallocene complexes A may also be used on a support material. Example Example 2 was repeated with the exception that different amounts of hydrogen, ethylene and propylene were fed to the reactor. The polymerization can be carried out batchwise or, preferably, continuously. Polymerization was carried out at a residence time of 1.
The temperature dependent seal strength data of examples 16 to 24 are given in Table 6. Low-crystalline propylene random copolymer composition, process for production thereof, and composite laminated polypropylene structure. Other suitable supports are fine-particle polyolefins, such as fine-particle polypropylene.
X 1X 2 and X 3 are hydrogen, C 1 -C 10 -alkyl, C 6 -C 15 -aryl, alkylaryl, arylalkyl, haloalkyl or haloaryl with in each case from 1 to 10 carbon atoms in the alkyl radical and from 6 to 20 carbon atoms in the aryl radical or fluorine, chlorine, bromine or iodine, in particular haloaryl, preferably pentafluorophenyl.
Product range also lumnus metallocene PP based on a simple drop-in technology. The reactors contain a bed of polypropylene powder, which is agitated below the fluidization point by a helical agitator to keep the novoen in motion and prevent powder agglomeration. The specimen was then loaded in machine direction into pneumatic grips 80 psi and run on tester. The polymer was removed from the autoclave and dried overnight at room temperature and atmospheric pressure.
The first random copolymer is characterized in that its propylene content is from above 90 to about novoolen The composition of claim 1 wherein said xylene soluble fraction has an intrinsic viscosity of above about 2.
As known in the art, the mutually exclusive requirements of low SIT and large amounts of unmelted material pummus high temperatures can only lkmmus optimized by producing blends of two or more random copolymers. Example 2 was repeated with the exception that different amounts of hydrogen, ethylene and propylene were fed to the reactor.

The support may also be subjected to treatment with novolne, e. It is usual for customary amounts of conventional additives, such as stabilizers, lubricants, mold-release agents, fillers, nucleating agents, antistats, plasticizers, dyes, pigments or flame retardants to be added to the polypropylene composition prior to its use.
The resin of Comparative Example 37 represents the high melting point component. Moreover, the balance between tensile modulus and level of solubles needs improvement.
The secant modulus, hexane extractables and seal initiation temperatures of the films of Examples 16 to 24 were determined as described above. Secant modulus is typically related to the stiffness of a film. Nonetheless, lunmus introduction of amorphous, low molecular weight bovolen into state-of-the-art metallocene lummua sealing layer compositions comprised of two or more pummus has been inevitable and is still too high with regard to food packaging applications.
A composition comprising a polymer blend of: The results in terms of population of fractions are set forth in Table 9. Particularly suitable metallocenium-ion-forming compounds B are open-chain or cyclic aluminoxane compounds of the general formulae V or VI where R 21 is C 1 -C 10 -alkyl, preferably methyl or ethyl, and m is an integer from 5 to 30, preferably from 10 to R 22 is hydrogen, C 1 -C 10 -alkyl, C 6 -C 15 -aryl, alkylaryl or arylalkyl having in each case from 1 to 10 carbon atoms in the alkyl radical and from 6 to 20 carbon atoms in the aryl radical.

The reactor contained an agitated bed of finely divided polymer. Specimens were tested on a black surface with a surface reflectance of less than 1 gloss unit.
The number of test specimens were chosen to permit an adequate determination of representative performance. Yet another embodiment of the present invention of the invention relates to a process for the polymerization of the compositions of the present invention. The support may also be treated chemically, generally using conventional drying agents, such as metal alkyl compounds, preferably aluminum alkyl compounds, chlorosilanes or SiCl 4.
Particularly preferred is a process that uses a reactor cascade of two reactors, wherein the polymerizations in both reactors are carried out in the gas phase. Example 24 Film of Example
