[0081] Polypropylene copolymer also includes long chain branched polypropylene copolymer.

[0082] Examples of suitable C4-C30 α-olefins are 1-butene, 1-

52/74 pentene, 1-hexene, 1-heptene, 1-octene, 1-nonene, 1-decene, 1-undecene, 1-dodecene, 1-tetradecene, 1-hexadecene, 1-octadecene, 1-eicosene, 4 -methyl-1-pentene, 1-eicosene, 1-docosene, 1-tetracosene, 1-hexacosene, 1-octacosene and 1-triacontene.

[0083] Examples of suitable C4-C20 alkanes are hexadiene and octadiene.

[0084] Examples of suitable C5-C12 cycloalkandienes include cyclopentadiene, cyclohexadiene and cyclooctadiene. Examples of suitable norbornene derivatives include 5-ethylidene-2-norbornene (ENB), dicyclopentadiene (DCP) and methylene-domethylene-hexahydronaphthaline (MEN).

[0085] A propylene / ethylene copolymer contains, for example, about 50% to about 99.9%, in some embodiments about 80% to about 99.9% and in other embodiments about 90% to about 99.9% by weight of propylene.

[0086] A propylene copolymer in which the comonomer is a C9-C20 α-olefin such as, for example, 1-nonene, 1-decene, 1-undecene, 1-dodecene, 1-tetradecene, 1-hexadecene, 1 -octadecene or 1-eicosene; C9-C20 alkanylene, C9-C12 cycloalkandiene or a norbornene derivative such as, for example, 5-ethylidene-2-norbornene (ENB) or methylene-domethylene-hexahydronaphthaline (MEN) may contain more than about 90% in mol, from about 90 mol% to about 99.9 mol% or from about 90 mol% to about 99 mol% of propylene.

[0088] Additional examples of polypropylene are copolymer of

Propylene / isobutylene, propylene / butadiene copolymer, propylene / cycloolefin copolymer, propylene and ethylene terpolymers and a diene such as hexadiene, dicyclopentadiene or ethylidene-norbornene; propylene / 1-olefin copolymers where 1-olefin is generated in situ; and propylene / carbon monoxide copolymers.

[0089] Ethylene or propylene oligomers terminated in allyl or vinyl can be used as branches in polymerization reactions with propylene to prepare branched polypropylenes of high melt strength in the manner described in United States Patent 8,399,725 and United States publications 2013 / 0274425, 2013/0274425, 2013/0030135 and 2013/0137829.

[0090] Structure of the linear polypropylene chain results in the polymer that exhibits low melt resistance and an absence of tension hardening. This can result in processing problems, where polymer extensibility is required. In contrast, polypropylenes that exhibit high melt strength are valued in industrial conversion operations such as blow molding, thermal molding or polypropylene foil foam. The polypropylene-based compositions of this invention exhibit acceptable melt strength, extensibility and stress hardening to produce extruded contours and coatings.

[0091] Advantageously, the polyolefin comprises a polypropylene homopolymer or copolymer of a suitable high melting strength, optically mixed with a polyethylene homopolymer or copolymer. The combination may additionally contain a third polymer suitable to facilitate compatibility, partial miscibility or miscibility of the different polyolefins. Such materials are referred to as interfacial tension reducing agents or compatibilizers.

[0092] Suitable compatibilizers are typically polymers that contain two or more different segments, each of which is

54/74 miscible or compatible with the individual components to be combined. A combination of compatible polymer need not be completely miscible, nor have to satisfy all the thermodynamics of the mixture (for example, resulting in a single phase, or single glass transition temperature), yet a combination of different polymer structures will exhibit better properties resulting in individual components.

[0093] One type of compatibilizer for combining PP and PE are segmented "olefin block copolymers" or "OBC", containing propylene, ethylene and optionally additional alpha-olefin sequences, such as those produced by Dow Global Technologies and prescribed in North American publications 2011/032621, 2011/060103, 2010/298515, 2011/054121 and 2011/015354. DUSE products with the trade name INFUSE and ExxonMobil VISTAMAXX are included. These block copolymers are produced with a global molecular hair distribution and segmented molecular weight distribution, such that Mw / Mn> 1.4, with two or more ethylene and alpha-olefin blocks per chain and low molecular weight (Mw <200,000 g / mol). These alternative block copolymers are characterized by segments of rigid, crystallizable "duct blocks" and an elastomeric, amorphous "soft block" content. The content of the hard block ranges from 12-84% by weight in those OBCs, and the total content of 1-octene (i.e., which confers long chain branches) ranges from 3 to 14% by weight. CBOs can match a combination of PP and HDPE, where an increase in elongation to break and tensile strength can be achieved, compared to a non-compatible combination of HDPE and PP.

[0094] The polypropylene homopolymer or copolymer, or combination with optionally compatible polyethylene, can be chemically cross-linked to introduce long chain branches (LCB)

55/74 outside the main polypropylene chain, resulting in greater melt strength and extensibility and less fluidity than is generally commercially available.

[0095] Chemical cross-linking of a polypropylene homopolymer or copolymer with another polypropylene or with a polyethylene homo- or copolymer, and / or with a compatibilization material is advantageous. Such crosslinking processes can impart a valuable increase in melt strength from polyolefin combination, melt extensibility, tensile strength and mechanics used in the present extrusion processes. Such cross-linking processes in polypropylene can produce long chain branches (LCB) in the polypropylene backbone, and create a greater amount of polymer chain tangles which results in greater polymer melt strength.

[0096] Crosslinking can be carried out with agents, such as organic peroxides, or by treatment with a radiation source, such as ultraviolet light, electron beam or gamma irradiation. The radiation can be carried out in an environment with reduced oxygen or zero oxygen, for example, a polypropylene of high melt strength and melt extensibility is obtained by combining a linear polypropylene with a branched polypropylene (b-PP) in an extruder . B-PP is prepared by reacting a peroxide with an unmodified polypropylene, and optionally a bifunctional unsaturated monomer, capable of grafting on the unmodified polypropylene to produce long chain branches, US2015175789. In another example, US patents 5,508,318,

5,731,362, 5,591,785, 5,554,668 and 4,916,198 describe composition of irradiated and non-irradiated olefin polymer material combinations, suitable for extrusion.

[0097] Unlike the downstream extrusion or chemical modification of the polymer to form crosslinking or long chain branches for

56/74 to improve melting strength, the formation of long chain branches in polyolefins can be conducted upstream during the manufacture of the polymer. In one example, polyethylene can be modified in a polymerization unit through exposure to a low level of oxygen, called “oxygen personalization”, resulting in the formation of long chain branching and greater fusion resistance, in the manner prescribed in the publication North American 2012/100357.

[0098] The polyolefin can contain an additive that promotes a higher level of crystallinity by melting, converting the polymer into molded articles. Such additives are referred to as nucleating agents.

[0099] The degree of crystallinity in polypropylene is an important parameter that influences properties such as modulus, yield stress, resistance, etc. It is within the scope of this invention to use nucleating agents that influence the favorable formation of a degree of crystallinity, which improves the melting resistance of the polymer during the extrusion process, and improves the mechanical properties in the final use of the article. Suitable nucleating agents are, for example, sodium benzoate, 2,2'-methylene-bis (4,6-di-tert-butylphenyl) phosphate, zinc glycerolate, 1,2-dicarboxylic acid cyclohexane calcium salt, aromatic compounds of trisamide, cis-endo-bicyclo [2.2.1] heptane-2,3-dicarboxylic acid disodium salt, hydroxy-bis [4- (tert-butyl) benzoate] aluminum and sorbitols such as 1.3: 2,4-bis (3,4-dimethyl-benzylidene) sorbitol 1,3: 2,4-bis (4-methylbenzylidene) sorbitol or 1,3: 2,4-bis (3,4-dimethylbenzylidene) sorbitol, da manner prescribed in US patents 7,423,088, 7,790,793 and

8,183,312 and North American publication 2012/0190797.

Nuclear agents can be present, for example, from about 10 parts per million (ppm) to about 10,000 ppm, from about 12 ppm to about 1,000 ppm, from about 12 ppm to about 500 ppm or from about 12 ppm to about 300 ppm or about 400 ppm, by weight based

57/74 in the weight of the polyolefin.

[00101] The polyolefin advantageously contains an inorganic (mineral) excipient to balance the melt strength and extensibility or tensile capacity to allow production by contour extrusion and coating. Excipients are described in more detail below.

[00102] The polyolefin comprising a polypropylene homopolymer or copolymer mixed optically with a polyethylene homopolymer or copolymer, where the combination may additionally contain a compatibilizer, may exhibit a high melt strength. The melt strength for the polyolefin can be at least about 4 centiNewtons (cN) at 210 ° C. For example, the melt strength of the polyolefin is about 4, about 5, about 6, about 7, about 8, about 9, about 10, about 11, about 12, about 13, about 14, about 15, about 16, about 17, about 18, about 19, about 20, about 21, about 22, about 23 about 24 or about 25 centiNewtons at 210 ° Ç. For example, the melt resistance is ≥ about 5, ≥ about 7, ≥ about 9, ≥ about 11, ≥ about 13, ≥ about 15, ≥ about 17, ≥ about 19, ≥ about 21 or ≥ about 23 centiNewtons at 210 ° C.

[00103] Polyolefins can be prepared by the following methods: a) radical polymerization (usually at high pressure and at high temperature) or b) catalytic polymerization using a catalyst that normally contains one or more of a metal from groups IVb, Vb, VIb or VIII of the Periodic Table. These metals generally have one or more of a binder, typically oxides, halides, alcoholates, esters, ethers, amines, alkyls, alkenyls and / or aryls that can have both pi- and σ- coordinates. These metal complexes can be in free form or fixed on substrates, typically in activated magnesium chloride, titanium (III) chloride, alumina or silicone oxide. These catalysts can be soluble or

58/74 insoluble in the polymerization medium. The catalysts themselves can be used in polymerization or additional activators can be used, typically metal alkyls, metal hydrides, metal alkyl halides, metal alkyl oxides or metal alkyloxanes, said metals being elements of groups Ia, IIa and / or IIIa of Periodic table. The activators can be modified conveniently with more ester, ether, amine or silyl ether groups. These catalyst systems are generally called Phillips, Standard Oil Indiana, Ziegler (-Natta), TNZ (DuPont), metallocene or single-site (SSC) catalysts.

[00105] In some embodiments, polyolefins include virgin polyolefin, recycled polyolefin or mixtures thereof. Recycled polyolefin can be obtained from household, commercial or industrial waste or from collections of used material. Recycled materials can originate from packaging materials, for example, films, bags, bottles and other containers or foams. It is also possible for polyolefins that were previously impaired by the use that storage or

59/74 processing is stabilized. These materials originate, for example, from collections of used material or return obligations, for example, from the automobile industry, electrical / electronic industry, construction, agriculture or the textile industry.

[00106] The incorporation of the present benzofuranones and organophosphate stabilizers in a polyolefin is carried out by known methods, for example, before or after molding or also by applying a mixture of additive dissolved or dispersed in the polyolefin, with or without subsequent evaporation of the solvent. The present benzofuranones and organophosphate stabilizers can also be added to a polyolefin in the form of a base mixture that contains the additives in a concentration of, for example, about 2% to about 40% by weight, based on the total weight of the mixture base. In the form of a base mixture, the polymer of the base mixture need not be the same as that of the polyolefin. Molding can be carried out with known mixing machines, for example, mixers, kneaders or extruders.

[00107] The present benzofuranones and organophosphate stabilizers can be pre-mixed or added individually. The present benzofuranones and organophosphate stabilizers can also be added before or during polymerization, or before cross-linking. The present benzofuranones and organophosphate stabilizers can be incorporated into a polyolefin in pure form or encapsulated in waxes, oils or polymers.

[00108] The present benzofuranones and organophosphate stabilizers can also be sprayed on a polyolefin. These are able to dilute other additives or their melts, in such a way that they can also be sprayed together with these additives in a polyolefin.

[00109] In certain embodiments, the present food additives

60/74 benzofuranone and organophosphate stabilizers are incorporated into a polyolefin by combining by melting in an extruder. The present benzofuranones and organophosphate stabilizers can be added together or separately.

[00110] In some embodiments, a process of preparing a polyolefin composition includes measurement of raw materials by weight, followed by the dry combination of raw ingredients.
