Description

RHEOLOGY MODIFIED ETHYLENE / ALPHA-OLEFIN / NONCONJUGATED POLYENE INTERPOLYMERS USING SULFUR SOURCES BACKGROUND OF THE INVENTION There is a need for ethylene / alpha-olefin / polyene interpolymers with high levels of long chain branching (LCB), and without significant crosslinking, as indicated by high MLRA / ML values and very low gel values, respectively. There is a further need for such interpolymers with high molecular weight as indicated by Mooney Viscosity (for example, ML (1+4, 125°C) ≥ 60). Such interpolymers should be suitable in applications, such as, for example, the formation of hoses, foamed, micro-dense and dense profiles, roofing membranes, wire and cable products, and other applications, for which conventional linear interpolymers are not well suited. Also, such interpolymers should be produced using processes that do not require an extensive oil extension of the interpolymer. U.S. Patent 3,817,952 discloses a process for producing a vulcanizable branched elastomeric polymer by mixing an EPDM copolymer with sulfur, a sulfur-releasing compound, or a peroxide, and subsequently heating the resultant mixture (see abstract). The copolymers are disclosed as having less than about 30% gel, a Wallace plasticity of about 30 to 100; and an inherent viscosity of at least about 2.0 at less than 30% gel (see abstract). This reference disclosed a gram-atom sulfur content from about 0.00125 to 0.00780 gram-atoms of sulfur per 100 grams copolymer, and prefers higher sulfur levels from about 0.00250 to 0.00625 gram-atoms of sulfur per 100 grams copolymer (see, for example, column 3, lines 1- 16). International Publication WO2020 / 263681 discloses a process that exposing a neat terpolymer to an electron beam radiation, at a dosage from 0.2 MRad to 1.3 MRad, to form a branched ethylene / propylene / non-conjugated polyene terpolymer (b-terpolymer) having a Mooney viscosity ML (1 +4) at 125°C from 25 MU to 135 MU. The neat ethylene / propylene / non-conjugated polyene terpolymer (n-terpolymer) has a Mooney viscosity (ML (1 +4) at l25°C) less than 100 Mooney units(MU). See abstract and claim 1. International Publication WO2022 / 115410 discloses a process of providing an ethylene / propylene / non-conjugated polyene terpolymer (EPDM) having at least 3.5 wt% non- conjugated polyene, and reacting the EPDM with a metal-Lewis acid, and forming a rheology-modified EPDM. The rheology-modified EPDM has (i) a z average molecular weight (Mz) from greater than 500,000 g / mole to 10,000,000 g / mole, (ii) a Mz / Mw from 3 to 10, (iii) a g value from 0.4 to 1.0, (iv) a z value from 1.0 to 3.5, (v) a Mooney viscosity from50 to 150, and (vi) a tan delta value from 0.1 to less than 1.0. See abstract. U.S. Publication 2014 / 0051809 discloses highly branched compositions including: (i) from about 96 wt % to about 99.9 wt % of a metallocene catalyzed ethylene propylene diene derived units; and (ii) from about 0.1 wt% to about 4 wt% of multifunctional monomer derived units, wherein the highly branched composition has: (a) a Mooney viscosity ML (1+4) at 125°C of about 30 to 100 MU, (b) a Mooney relaxation area MLRA of about 100 to about 1000, (c) a St. index, g’(vis) of less than about 0.9, (d) a phase angle, δ, of less than about 55 degrees at a complex modulus of 10 kPa, measured at 190°C, and (e) a degree of shear thinning greater than about 0.95, measured at 190°C.

However, as discussed above, there remains a need for ethylene / alpha-olefin / polyene interpolymers with high levels of long chain branching (LCB), and without significant crosslinking, as indicated by high MLRA / ML values and very low gel values, respectively. There is a further need for such interpolymers with high molecular weight as indicated by Mooney Viscosity. These needs have been met as discussed below. SUMMARY OF THE INVENTION A composition comprising a “rheology modified ethylene / alpha-olefin / nonconjugated polyene interpolymer” that comprises the following properties: i) a MLRA / ML (at 125°C) value ≥ 8.0 s, and ii) a gel content ≤ 10.0 wt%, based on the weight of the “rheology modified ethylene / alpha-olefin / nonconjugated polyene interpolymer;” and wherein the “rheology modified ethylene / alpha-olefin / nonconjugated polyene interpolymer” is formed from a first composition comprising the following components: a) an ethylene / alpha-olefin / nonconjugated polyene interpolymer and b) at least one sulfur source. BRIEF DESCRIPTIONS OF THE DRAWINGS Figure 1 depicts the relaxation torque curve for a “rheology modified ethylene / alpha- olefin / nonconjugated polyene interpolymer (Example R4).” DETAILED DRESCRIPTION OF THE INVENTION It has been discovered that an ethylene / alpha-olefin / nonconjugated polyeneinterpolymer can be rheology modified, using one or more sulfur sources, to form a modified interpolymer having an overall increase in rheological properties (such as low-shear viscosity and shear thinning), relative to the unmodified interpolymer, and having minimal gel formation or crosslinking. This rheology modification allows for the formation of long chain branching (LCB) within the interpolymer, which results in an interpolymer having a significantly increased elasticity and increased shear thinning behavior, relative to the unmodified interpolymer. Additional benefits of a high “LCB content” interpolymer (versus a more linear interpolymer) are reduced cold flow, higher green strength, higher collapse resistance during extrusion of hollow parts, better foamability, faster extrusion rates, faster mixing, lower energy consumption in internal mixers, higher filler loading, and reduced melt fracture. These rheological properties are of significant value in calendaring and extrusion applications, such as, for example, the formation of hoses, foamed, micro-dense and dense profiles, roofing membranes, wire and cable products, and other applications. It has been discovered that a post-reactor chemical modification approach can be used to incorporate high levels of LCB into the interpolymer, without forming a significant amount of crosslinking. It was discovered that using small amounts of a one or more sulfur sources, optionally in combination with one or more activators, caused the formation of LCB in EPDM, without significant gel formation or crosslinking. EPDM, thus made, had exceptional elasticity, high viscosity and shear thinning behavior.

TEST METHODS Mooney Viscosity and Mooney Relaxation Area (MLRA) (Neat Interpolymer and Rheology modified Interpolymer) Mooney viscosity was measured using ASTM D1646, with a one minute preheat time and a “four minute” rotor operation time, followed by a two minute relaxation time. The instrument was an Alpha Technologies Mooney Viscometer 2000. The conditions used forthe neat interpolymer samples and for the for the rheology modified interpolymer samples were (ML 1+4 @ 125°C). About a 7-14 gram sample size was used. The Mooney Relaxation Area (MLRA) data was obtained from the Mooney viscosity measurement, where the test sample was relaxed after the rotor was stopped. At the end of the Mooney viscosity test, the rotation of the disk was stopped within 0.1 seconds. Collection of relaxation data typically began one second after the rotor was stopped, and continues for at least two minutes after the rotor was stopped. The MLRA value reported is the integrated area under the Mooney torque relaxation time curve from 1 second to 120 seconds (MLRA (1 + 4 + 2)). The MLRA value indicates the degree of elasticity of a polymer, and can be regarded as a stored energy term. Higher MRLA values indicate that, after the removal of an applied strain, the test sample stores more energy and requires more time to relax (that is, to dissipate the stored energy). Polymers with more elasticity (for example, those with a more long chain branched (LCB) structure, typically exhibit higher MLRA values compared to less elastic polymers (for example, those having a less long chain branched structure)). The MLRA is reported in Mooney Unit - seconds (MU·s). The term “MLRA / ML ratio," as used herein, is the “Mooney Relaxation Area - to - the Mooney viscosity” ratio, and this notation is an abbreviated form for “MLRA / ML(1 + 4) @ 125°C.” The MLRA / ML ratio indicates the degree of melt elasticity of a polymer and is directly proportional to the degree of melt elasticity. The MLRA / ML ratio is reported in seconds (s). As an example, the results for rheology modified interpolymer R4 (see Table 2B below) are shown below, and the resulting relaxation torque curve (viscosity versus test time) is shown in Figure 1. Test Type Viscosity; Test Temp 125.0 C; Test Time 4.00 min; Preheat 1.00 min; Rotor Size Large; Relaxation Time 2.00 min; Init Point 191.76 MU; ML 130.98 MU; MH 134.72 MU; Final Viscosity 104.6 MU; ML(1+2) 124.18 MU; ML(1+4) 104.57 MU (noted as “105” in Table 2B); ML(1+6) 10.34 MU; ML(1+8) MU; ML(1+10) MU; Decay Slope -0.3630 MU; Intercept 56.8 MU; RCoeff -0.9992; MRIAREA 995.45; TX80 15.10 s; Instrument Name MV3; Area 1794.36 MU·s. Thus, the MLRA / ML = (1794.36 MU·s / 104.57 MU) = 17.2 s. Rubber Process Analyzer (RPA) (Neat EPDM and Rheology modified EPDM) Dynamic viscoelastic properties were measured as per ASTM D6204 with a rotorless oscillating shear rheometer (i.e., rubber process analyzer (RPA)). An RPA frequency sweepwas performed at 125°C, using a 7% strain for the neat and rheology modified interpolymer samples, using an Alpha Technologies RPA 2000. The test sample was cut out with a Cutter 2000R. The sample size was between 5 and 7 grams. The test sample was considered to be of proper size (116 to 160% of the test cavity volume) when a small bead of the interpolymer was extruded uniformly around the periphery of the dies as they were closed. The sample was placed between two pieces of MYLAR film. A frequency sweep was performed as discussed above. The angular frequency range was from 0.1 rad / s to 100 rad / s. The stress response was analyzed in terms of amplitude and phase, from which, the storage shear modulus (G’), loss shear modulus (G”), complex viscosity (η*), tan delta (that is a phase angle δ), and complex shear modulus G* were calculated. Modulus values were reported in kilopascal (kPa), phase angle was reported in degrees, and viscosity was reported in kPa·s. The properties recorded were complex viscosity (η*) at 0.1 rad / s and 100 rad / s and rheology ratio. The “rheology ratio” (or “RR”), was calculated as the ratio of the complex viscosity at 0.1 rad / s, and 125°C, to the complex viscosity at 100 rad / s, and 125°C; RR equals ƞ0.1 / ƞ100, at 125°C. Gel Content The gel content (insoluble fraction) produced by crosslinking, during the rheology modification, was determined by extracting the rheology modified interpolymer with xylene (certified ACS grade, CAS: 1330-20-7), which was purchased from Fisher Scientific. See ASTM D2765-16, Standard Test Methods for Determination of Gel Content and Swell Ratio of Crosslinked Ethylene Plastics, ASTM International, West Conshohocken, PA, 2016, www.astm.org. The xylene extraction sample holder was prepared by cutting a piece of 120-mesh stainless steel mesh measuring approximately 80 mm by 40 mm (3 in. by 1.5 in.). The mesh was folded in half to form a square measuring approximately 40 mm (1.5 in.) for each side. The two sides of this square were closed to form an open mesh pouch by folding the mesh at the edges and stapling the folds. The open sample holder was weighed to four decimal places (W1). For each rheology modified interpolymer, 0.3 grams of the interpolymer (cut into approximately 3 mm3pieces) was placed into a prepared open mesh pouch. The open mesh pouch and interpolymer, contained therein, were weighed to four decimal places (W2). The open side of the mesh pouch was then folded over and stapled shut, to create a closed mesh envelope, which was weighed to four decimal places (W3).The closed mesh envelope containing the rheology modified interpolymer, was suspended in 4 liters of refluxing xylene, containing 40 grams of an antioxidant (2,2’- methylene-6-tertiary butyl phenol) and boiling chips, The refluxing continued for 12 hours. At the end of 12 hours, the closed mesh pouch was removed from the xylene, and immediately dried in a vacuum oven at 150°C, with a nitrogen flow of approximately 5 PSI, for 12 hours. At the end of 12 hours, the dried closed envelope was weighed to four decimal places (W4), for a determination of the gel content of the rheology modified interpolymer. Each rheology modified interpolymer was run in duplicate, and the average result was reported as weight percent of gel content (Gel content (wt%)). The gel content of each rheology modified interpolymer was calculated as follows: Extract (wt%) = (W3-W4) / (W2-W1) x 100%], where W1 = weight of the mesh pouch, sealed on three sides (2 sides stapled), one side open; W2 = weight of the mesh pouch and the interpolymer (before extraction), and where the mesh was sealed on three sides, with one side open; W3 = weight of the mesh pouch and the interpolymer (before extraction), and where the mesh was sealed on all sides to create a closed pouch; W4 = weight of the closed mesh and interpolymer after extraction and drying. Gel content (wt%) = 100 - Extract (wt%). Gel Permeation Chromatography (GPC) The chromatographic system consists of a PolymerChar GPC-IR (Valencia, Spain) high temperature GPC chromatograph, equipped with an internal IR5 infra-red detector (IR5). The autosampler oven compartment is set at 160º Celsius, and the column compart- ment is set at 150º Celsius. The columns are four AGILENT “Mixed A” 30 cm, 20-micron linear mixed-bed columns. The chromatographic solvent is 1,2,4-trichlorobenzene, which contained 200 ppm of butylated hydroxytoluene (BHT). The solvent source is nitrogen sparged. The injection volume is 200 microliters, and the flow rate is 1.0 milliliters / minute. Calibration of the GPC column set is performed with 21 narrow molecular weight distribution polystyrene standards, with molecular weights ranging from 580 to 8,400,000, and which are arranged in 6 “cocktail” mixtures, with at least a decade of separation between individual molecular weights. The standards are purchased from Agilent Technologies. The polystyrene standards are prepared at 0.025 grams in 50 milliliters of solvent, for molecular weights equal to, or greater than, 1,000,000, and at 0.05 grams in 50 milliliters of solvent, for molecular weights less than 1,000,000. The polystyrene standards are pre-dissolved at 80° Celsius, with gentle agitation, for 30 minutes then cooled, and the room temperature solutionis transferred cooled into the autosampler dissolution oven (equilibrated at 160°C) for 30 minutes. The polystyrene standard peak molecular weights are converted to polyethylene molecular weights using Equation 1 (as described in Williams and Ward, J. Polym. Sci., Polym. Let., 6, 621 (1968)): ^= ^ × ^^^^^^^^^^^^^ ^^^^^^^^^^^^^^ (EQ 1),where M is the to 1.0. A fifth order polynomial is used topoints. The total plate count of the GPC column set is performed with decane which was introduced into a blank sample via a micropump controlled with the PolymerChar GPC-IR system. The plate count for the chromatographic system should be greater than 18,000 for the four Agilent “Mixed A” 30 cm, 20-micro linear mixed-bed columns. Samples are prepared in a semi-automatic manner with the PolymerChar “Instrument Control” Software, wherein the samples are weight-targeted at 2 mg / ml, and the solvent (contained 200 ppm BHT) was added to a pre nitrogen-sparged, septa-capped vial, via the PolymerChar high temperature autosampler. The samples are dissolved for 3 hours at 160º Celsius under “low speed” shaking. The calculations of Mn(GPC), Mw(GPC), and Mz(GPC) are based on GPC results using the internal IR5 detector (measurement channel) of the PolymerChar GPC-IR chromatograph according to Equations 2-4, the PolymerChar GPCOne™ software, the baseline-subtracted IR chromatogram at each equally-spaced data collection point (i), and the polyethylene equivalent molecular weight obtained from the narrow standard calibration curve for the point (i) from Equation 1. ^^(^^^) = ∑^ ^^^^(E ^^^^Q 2), 3),4).In order to monitor the deviations over time, a flowrate marker (decane) was introduced into each sample, via a micropump controlled with the PolymerChar GPC-IR system. This flowrate marker (FM) is used to linearly correct the pump flowrate (Flowrate(nominal)) for each sample, by RV alignment of the respective decane peak withinthe sample (RV(FM Sample)), to that of the decane peak within the narrow standards calibration (RV(FM Calibrated)). Any changes in the time of the decane marker peak are then assumed to be related to a linear-shift in flowrate (Flowrate(effective)) for the entire run. After calibrating the system, based on a flow marker peak, the effective flowrate (with respect to the narrow standards calibration) is calculated from Equation 5. Processing of the flow marker peak was done via the PolymerChar GPCOne™ software. Acceptable flowrate correction is such that the effective flowrate should be within + / -0.5% of the nominal flowrate. Flowrate(effective) = Flowrate(nominal) * (RV(FM Calibrated) / RV(FM Sample)) (EQ 5).

Batch Mixer Modification – (40 grams)- Table 2A First compositions each containing the EPDM (40 g) were modified on a RS5000 Batch Mixer from Rheometers Services Inc.. The small bowl, with roller blade rotors, suitable for mixing batches up to 45 g, was used. After initial fluxing of the base polymer (EPDM) for a minute (200oC, 5 rpm), the remaining ingredients in the formulation were loaded in the mixer, as discussed below, at a low speed (for about 2 minutes, 5 rpm). Following incorporation of all other ingredients, a rotor speed of 50 rpm and a bowl temperature of 200°C were used, unless noted otherwise. The mixing was continued for an additional six minutes. After mixing, the batch was collected on a glass reinforced TEFLON sheet, and pressed into a flat ‘patty’ (approximate 0.25” thickness) on a compression molder (Carver Hydraulic Press, Duration of compression 3-5 minutes, Pressure approx.20,000 psi, Temperature 20-25oC). The flat ‘patty’ was cooled to ambient temperature. Depending on the individual ingredient, different methods of addition to the batch mixer were used. All pellets and pastilles were directly added. Ingredients in powder form were weighed on a film formed from the base resin (EPDM), and then rolled by hand (used nitrile gloves) to form a “burrito-shaped” encapsulant. The EPDM film had a thickness of approx.1-2 mm, and was prepared by compression molding 20-30 grams of the EPDM at 100-120°C, at a pressure of approx.20,000 psi, for 3 minutes. A portion of the film (about 3- 4 g) was used as the film for the encapsulant. The rolled encapsulant was then added to the mixer. The amount of EPDM in Table 2A includes the amount of the EPDM used to form the film for the encapsulant. Twin Screw Extruder Modification (5 lbs) – Table 3A Preparation of the Masterbatch (MB) A sulfur-activator masterbatch in pellet form was made, using ENGAGE 8180 Polyolefin Elastomer as the carrier resin, to enable the ease of feeding of other components. The masterbatch composition contained ENGAGE 8180 Polyolefin Elastomer (100 wt. parts), Sulfur (3 weight parts), and Zinc Stearate (57 wt. parts). The ENGAGE 8180 Polyolefin Elastomer was loaded in a batch mixer and fluxed, after which, the sulfur and zinc stearate were added. Mixing was performed at 40 rpm, until the temperature reached 100°C.The batch was then pelletized using a single screw extruder. Preparation of the Rheology Modified Interpolymers The first compositions, as shown in Table 3A, were extruded using a “26 mm,” co- rotating twin screw extruder (ZSK-26 from Coperion Corp.). The extruder was configured with 15 barrels (60 L / D). The maximum screw speed was 1200 rpm, and the maximum motor output was 40 HP. The extruder was equipped with a “loss-in-weight feeder.” All components were added simultaneously to the extruder via the extruder feed throat. Barrel 1 was water cooled (temp. less than 70°C), and Barrels 2-15 were maintained at 210°C. A two-hole die was used to produce strands, which were pulled through a water bath and subsequently cut into pellets using a strand cutter. A run rate of 4.5 lbs / hr and a screw speed of 150 rpm were used. Results The Mooney Viscosity and the rheological properties of each rheology modified interpolymer, prepared in the Batch mixer, are shown in Table 2B. The gel contents of some of the rheology modified interpolymers are also shown in Table 2B. The control, first composition A was not thermally treated, but tested as is. Control, first compositions B and E were each thermally treated in the batch mixer as discussed above. Tables 2C and 2D provide the ratios of some properties of the rheology modified interpolymers, relative to the noted control interpolymers. For the first composition Inv.6, containing the TMTD, it is believed that the ZnO may help to release sulfur from the TMTD, and then complex strongly with the released sulfur. Thus, more sulfur is needed to significantly modified the interpolymer. See Table 2A. Example R6 had a MLRA / ML value of 16.0 s and a gel content of 2.9 wt%. As seen in Table 2B, for examples R1 and R2, a very small amount of sulfur, 100-300 ppm, based on the amount of the EPDM (before rheology modification), achieved rheology modification of the EPDM (NORDEL 4785). This is seen in the increase in the following properties: shear rate viscosity at 0.1 rad / s, Mooney viscosity, shear thinning behavior (rheology ratio) and the MLRA / ML ratio, relative to the control example (see A). Examples R1 and R2 also has very low gel levels of 0.9 wt% and 0.7 wt%, respectively, indicating that these modified interpolymers had a minimal amount of, if any, crosslinking. At 500 ppm sulfur (see example R2’), the MLRA / ML ratio (18.6 s) was higher (among other properties), and the modified EPDM had gel content of 8.6 wt%. Also, as seen for examples R4 and R5, the use of an activator (zinc stearate), inconjunction with a low amount of sulfur (300 ppm and 200 ppm) produced rheology modified interpolymers with high MLRA / ML values (17.2 s and 8.5 s) and low gel levels (4.0 wt% and 1.1 wt%). It is noted that example RG, formed using 1000 ppm sulfur, had a gel content of 33.1 wt%, indicating a significant degree of crosslinking within the modified interpolymer. Example R7, formed from a mercapto functional silicone copolymer, had a MLRA / ML value of 8.8 s and a low gel content of 0.3 wt%. The Mooney Viscosity and the rheological properties of each rheology modified interpolymer, prepared in the twin screw extruder, are shown in Table 3A. The gel contents of some of the rheology modified interpolymers are also shown in Table 3A. The control, first compositions J and K were each thermally treated in the twin screw extruder as discussed above. Tables 3B and 3C provide the ratios of some properties of the rheology modified interpolymers, relative to the noted control interpolymers. As seen in Table 3A, for example R11, 320 ppm sulfur, based on the amount of the EPDM (before rheology modification), achieved rheology modification of the EPDM (NORDEL 4785). R11 had a high MLRA / ML value (10.4 s) and low gel content (3.3 wt%). Example R12, prepared with 320 ppm sulfur, had a high MLRA / ML value (12.2 s) and a gel content (9.2 wt%). See also R9 prepared with 380 ppm sulfur, based on the amount of the EPDM (NORDEL 4760), and with a MLRA / ML value of 13.0 s and low gel content of 0.4 wt%.Table 2A: First Compositions – Batch Mixer (wt. parts) CompComp Comp trol Control E-beam In Comp Con v Inv Inv Control Inv First Comp.
