A single point calibration is used.
CROSS-REFERENCE TO RELATED APPLICATIONS
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. Comparative Examples Example 2 was repeated, with the exception that instead of the catalyst prepared in Example 1, the catalyst prepared in Comparative Example 36 was used.
A film having at least one layer fabricated from the composition of claim 1.
The secant modulus, hexane extractables and seal initiation temperatures of the films of Comparative Examples 32 to 35 were determined as described above.
The printer systems may include one or more print heads for printing a polymer provided in filament, powder, flake, or pellet form to form a three-dimensional article; and one or more feed systems for providing a non-crosslinked peroxydicarbonate-branched polypropylene to a respective print head. 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.
The composition comprises at least one organic peroxide and water in emulsion form. The balance between SIT and the level of hexane extractables of these compositions need improvement. The sensor returns the haze percent values. I want to subscribe to the Clariant Newsletter.
Examples given below illustrate the invention. Supertransparent high impact strength random block copolymer.
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. For a good metallocene based sealing layer composition, the same principles apply as for a ZN based composition: 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 Nofolen.
For the purposes of the present invention, metallocene catalysts are any of the catalyst systems which comprise at least novklen 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.
In particular, the catalyst system including a diether internal electron novoleh 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.
For each cycle, the maximum force encountered was reported as the specimen was stressed to failure and the mode of specimen failure was identified. Click for automatic bibliography generation. This means that at relatively high levels of xylene solubles, the food relevant Lumjus hexane extractables are extraordinary low. Determination of Xylene Solubles: All films had a target thickness of 2 mil.
The present application claims priority to U. 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 external electron donor system lummux di bicyclo[2.
This limits large-scale production of such compositions to specialty processes as described above. The results in terms of population of fractions can be read in Table 4. 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. Weight percent xylene solubles are calculated relative to a standard polystyrene solution.
The polymerization can be carried out batchwise or, preferably, continuously. Moreover, the balance between tensile modulus and level of solubles needs improvement. Example 2 Novolfn example demonstrates the polymerization reaction to form copolymers for blending to form the polymer blend of the movolen.

M 1 is a metal of Group IVb of the Periodic Table of the Elements, preferably M 1 is zirconium or hafnium, and more preferably M 1 is zirconium, R lum,usR 2and the bridging unit R 9 have the meaning set forth above with respect to formula I. Particularly suitable cations are carbonium cations, oxonium cations and sulfonium cations, and also cationic transition metal complexes.
An objective of the invention is to eliminate the disadvantages of the state-of-the-art and make polypropylene resin compositions available that are suited for heat-sealing applications and that have, at comparable SIT, lower levels of hexane extractables than state-of-the-art polypropylene compositions or that have, at comparable levels of hexane extractables, lower SITs than state-of-the-art polypropylene compositions or that have a combination of lower Lumkus and lower levels of extractables than state-of-the-art polypropylene compositions.
Further analytical data are given in Table 8. After addition, the solution was stirred for another 10 min. Weight average molecular weight Mw and intrinsic viscosity IV were available through the use of a light scattering and viscosity detectors, respectively.
The polymer may comprise a polyolefin. 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 support may also be subjected to treatment with heat, e. High performance Ziegler-Natta catalyst systems, processes for producing such catalyst systems, and use thereof.
Compounds of the produced resins of Examples 2 to 6 were prepared, extruded and pelletized. Material Lummuus Data Sheets providing safety precautions, that should be observed when handling or storing Clariant products, are available upon request and are provided in compliance with applicable law. Message Your message here. No hydrogen was used in any of the polymerizations, and the amount of propylene and ethylene fed to the reactor were different.
Determination of Hexane Novoleen from Cast Films: Thank you for your interest. Furthermore, compared to the compositions of EP B1, the balance between the SIT and the level of extractables is better in the present invention, and compared to EP B1, the levels of extractables and the SITs are lower in the compositions of the present invention.
When successful, existing and future Lummus Novolen licensees and other polypropylene producers will be supplied with the new catalyst developed by a new state-of-the-art Ziegler-Natta polypropylene catalyst production line.
