Specimen width was 1. The processes may include providing a non-crosslinked peroxydicarbonate-branched polypropylene filament, flake, pellet, or powder adapted for one of a fused deposition modeling Arburg Plastic Freeforming printer or a fused filament fabrication printer; and printing the non-crosslinked peroxydicarbonate-branched polypropylene with fused deposition modeling Arburg Plastic Freeforming printer or a fused filament fabrication printer to form a three-dimensional article.
A process and printer systems for printing a three-dimensional object are disclosed. Due to possible changes in our products and applicable national and international regulations and laws, the status of our products could change. Metallocene compounds, catalysts comprising them, process for producing an olefin polymer by use of the catalysts, and olefin homo- and copolymers.
The first solid catalytic component may include: Examples Compounds of the produced resins of Examples 2 to 6 were prepared, extruded and pelletized. As known in the art, the mutually exclusive requirements of low SIT and large amounts of unmelted material at high temperatures can only be optimized by producing blends of two or more random copolymers. On top of that, the amount of comonomer that has to be incorporated into the low crystallinity fraction of the composition is significantly lower than in prior art of comparable SIT.
The objective of the invention is achieved by polypropylene compositions that exhibit xylene soluble fractions with very high molecular weight, and by polypropylene compositions that comprise ultra-low crystallinity fractions, and also by a process for preparing the polypropylene compositions. This means that at relatively high levels of xylene solubles, the food relevant FDA hexane extractables are extraordinary low.
The following specifications were used for running the device: The polypropylene Ziegler-Natta catalyst market is expected to continue the high growth pace shown over the last decade with estimated growth rates of more than five percent in the next five years.
One preferred method is to carry out polymerization in the presence of a suitable catalyst in a series of different reactors, for example in a reactor cascade with at least two different reactors, with conditions in the reactors sufficiently different to give the final composition desired. Determination of Xylene Solubles: The films or film layers of the present invention exhibit very low proportion of extractables, very low seal initiation temperature, and a good balance of stiffness, toughness and transparency.
I allow Clariant to store and process my information for the purpose given in this contact form. The composition of claim 13 wherein said xylene soluble fraction has an intrinsic viscosity of above about 2. In particular, the catalyst system including a diether internal electron donor may have an activity and hydrogen response suitable for the production of propylene polymers having a molecular weight distribution PI GPC in the range from about 5.
The disclosure relates to a method for modifying the rheology of a polymer and a polymeric composition obtained by the method. The polymer may comprise a polyolefin. As the result of the combinations of the methods of the determination of the xylene solubles after extended settling time and the TREF, we report 5 fractions: A sample was subjected to the same experimental recipe with the exception that the sample was allowed to settle for another 5 days instead of another 2 hours.

The composition of claim 1, wherein both random copolymers of the polymer blend were prepared by means of a metallocene catalyst. The sensor returns the haze percent values.
Please enter your contact information so we are able to process your request. Comparative Example 36 Example 1 was repeated with the exception that instead of the metallocene rac-dimethylsilanediyl 2-methyl para-tert-butyl-phenyl -indenyl 2-isopropyl para-tert-butyl-phenyl zirconiumdichloride, the metallocene rac-dimethylsilanediylbis 2-methyl-indenyl zirconiumdichloride was used.
The process of claim 25, wherein the polymerizing steps c and e are performed using a reactor cascade composed of at least two reactors in series. This limits large-scale production of such compositions to specialty processes as described above or in EP B1. A low SIT is related to large amounts of the sealing layer material melting at temperatures as low as possible, but above room temperature.
In all cases, the completeness of the fractionation was illustrated by the fact that a maximum of 0. I found Clariant through a search engine. Material was cut into strips in the machine direction and lummks seal was made across the strip and then pulled with the long tabs in the novoln.
For the purposes of the present invention, metallocene catalysts are any of the catalyst systems which comprise at least one metallocene compound Aand metallocenes compounds A here are any of the complex compounds of metals of transition groups of the Periodic Table with organic ligands.
Nonetheless, the introduction of amorphous, low molecular weight fractions into state-of-the-art metallocene based sealing layer compositions comprised of two or more components has been inevitable and is still too high with regard to food packaging applications. Example 20 Film of Example The following films were prepared:. The amount of strong neutral Lewis acids, of ionic compounds with Lewis-acid cations or of ionic compounds with Bronsted acids bovolen cations is preferably from 0.
A catalyst system for the polymerization of olefins may include a first solid catalytic component and a second solid catalytic component. 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 results in terms of population of fractions are set forth in Table 9. Those skilled in the art will envision many other embodiments within the scope and spirit of the invention as defined by the claims appended hereto.
Particular, but non-limiting examples are ethylene, 1-butene, 1-pentene, 1-hexene, 4-methylpentene and 1-octene. The metallocene complexes A may also be used on a support material.
CROSS-REFERENCE TO RELATED APPLICATIONS
The process may include contacting, in a gas phase polymerization reactor, propylene and optionally one or more comonomers with a catalyst system comprising a Ziegler-Natta catalyst and an novolwn electron donor system comprising di bicyclo[2. You ulmmus about to leave the Clariant domain close.
Lum,us a good metallocene based sealing layer composition, the same principles apply as for a ZN based composition: The composition of claim 1 wherein said xylene soluble fraction has an intrinsic viscosity of above about 1. The resins of Examples 2, 3 and 4 represent the high onvolen point component used in the polymer blend of the invention. This metallocene topology affords high melting point, very high molar mass homo polypropylene and very high molar mass propylene-based copolymers.
The hexane extractables from the film of Comparative Example 35 made from the polymer blend of Comparative Example 31 was 4. This information corresponds to the present state of our knowledge and is intended as a general description of our products and their possible applications. After the discharging, the extractor was heated to the next elution temperature and ml of xylene at the same temperature were added.
A wide range of products can be produced with, at nivolen, two reactors connected in series, including super-highimpact copolymers. Example 2 This example demonstrates the polymerization reaction to form copolymers for blending to form the polymer blend of the invention.
