Description
COMPOSITIONS CONTAINING ANHYDRIDE / ACID FUNCTIONALIZED ETHYLENE / ALPHA-OLEFIN INTERPOLYMERS AND SILANE FUNCTIONALIZED TACKIFIERSBACKGROUND OF THE INVENTIONA packaging hot melt adhesive (HMA) is typically formulated with low viscosity polymer, tackifier and wax to form a final composition with a given performance property profile. The design and selection of the components can have big impact on the adhesion of the HMA to a substrate, especially a substrate that contains a propylene-based polymer, such as, for example, a BOPP (Biaxially Oriented Polypropylene) film laminated corrugated cardboard. There is a need for HMA compositions with good adhesion to substrates that contain a propylene-based polymer, over a wide temperature range (for example, -20℃ to 60℃) .U.S. Publication 2015 / 0166853 discloses a composition comprising the following components: A) an anhydride and / or carboxylic acid functionalized ethylene / alpha-olefin interpolymer having the following properties: i) a melt viscosity (177℃) less than, or equal to, 50,000 cP, ii) a MWD from 1.5 to 5, and iii) a density from 0.855 to 0.900 g / cc; B) a tackifier; and C) a wax. See abstract. Such composition can be used to bond “hard to bond” substrates (see paragraph
[0002] ) . The composition can be used with the following substrates: wax coated Kraft or carton, polyethylene coated Kraft or carton, BOPP film laminated Kraft or carton, polypropylene (PP) film laminated Kraft or carton, PET film laminated Kraft or carton, clay coated Kraft or carton, lacquer coated Kraft or carton, and combinations thereof (see paragraphs
[0092] -
[0100] ) . Examples of tackifying resins include aliphatic, cycloaliphatic and aromatic hydrocarbons, and modified hydrocarbons and hydrogenated versions; terpenes and modified terpenes and hydrogenated versions; and rosins and rosin derivatives and hydrogenated versions; and mixtures thereof (see paragraph
[0079] ) .U.S. Publication 2021 / 0198473 discloses a composition comprising an acid and / or anhydride grafted ethylene / alpha-olefin interpolymer that comprises the following properties: A) number of grafts per polymer chain ≥ 1.80, and B) melt viscosity (at 177℃) ≤ 50,000 mPa·s (see abstract) . The composition can be used with “hard to bond” substrates (see paragraphs
[0001] -
[0002] ) . Examples of tackifiers include aliphatic, cycloaliphatic and aromatic hydrocarbons and modified hydrocarbons and hydrogenated versions; terpenes and modified terpenes and hydrogenated versions; and rosins and rosin derivatives and hydrogenated versions; and mixtures of two or more of these tackifiers (see paragraph
[0081] ) .U.S. Patent 10,954,420 discloses a curable petroleum resin comprising a repeating unit derived from a petroleum resin monomer, a repeating unit derived from a silane monomer and a repeating unit derived from a C3-C20 alpha-olefin monomer. The curable petroleum resin is disclosed as used as an additive in a reactive polyolefin-based adhesive composition to increase the adhesive strength to a polyolefin-based substrate used for various parts. See abstract. The reactive polyolefin-based adhesive composition is prepared by mixing a polyolefin-based base polymer with a catalyst for the curing reaction and a petroleum resin for the increase of the adhesive force (see column 4, lines 55-58) . The polyolefin-based base polymer may be a polyalpha-olefin, polyolefin alone, a copolymer thereof or a blend thereof. The polyalpha-olefin may be one prepared by copolymerizing linear alpha-olefins such as I-butene, 1-pentene, 1-hexene, 1-heptene, 1-octene, 1-decene, 1-undecene, 1-dodecene, 1-tetradecene, 1-hexadecene and 1-itocene. The polyolefin may be polyethylene, polypropylene alone or a copolymer thereof. If desired, the polyalpha-olefin and polyolefin may be used as it is, or may be one modified with silane (see column 10, line 63, to column 11, line 5) .EP3480225A2 discloses a curable petroleum resin that comprises a repeating unit derived from a petroleum resin monomer, a repeating unit derived from a silane monomer and a repeating unit derived from a cyclic anhydride monomer. The curable petroleum resin is disclosed as used as an additive for a reactive polyolefin-based adhesive composition to increase the adhesive strength to a polyolefin-based substrate used for various parts. See abstract. In a reactive polyolefin-based adhesive composition, a petroleum resin is mixed with a polyolefin-based base polymer in order to increase adhesive strength with a catalyst for a curing reaction (see paragraph
[0037] ) . As one example, the polyolefin-based base polymer may be polyalpha-olefin, polyolefin alone, a copolymer thereof, or a blend thereof. The polyalpha-olefin may be obtained by copolymerizing linear alpha-olefin such as 1-butene, 1-pentene, 1-hexene, 1-heptene, 1-octene, 1-decene, 1-undecene, 1-dodecene, 1-tetradecene, 1-hexadecene and 1-eicosene, and the polyolefin may be polyethylene or polypropylene alone, or a copolymer thereof. When necessary, the polyalpha-olefin and the polyolefin may be used as they are, or may be silane modified (see paragraph
[0083] ) .Additional adhesive compositions and / or components thereof are disclosed in the following references: EP3647333 A1, WO2009 / 029476, US7199180 and Technical Datasheet: HRR-100, Kolon Industries, May 25, 2021.However, challenges exist for improved adhesion toward substrates containing propylene-based polymers.

The spindle is a SC-31 hot-melt spindle, suitable for measuring viscosities in the range from 10 to 100,000 centipoise (cP) . The sample (polymer or composition) is poured into the chamber, which is, in turn, inserted in to a Brookfield Thermosel, and locked into place. The sample chamber has a notch on the bottom that fits the bottom of the Brookfield Themosel, to ensure that the chamber is not allowed to turn when the spindle is inserted and spinning. Then sample (approximately 9.5 grams of polymer or composition) is heated to the required temperature, until the melted sample is about one inch below the top of the sample chamber. The viscometer apparatus is lowered, and the spindle submerged into the sample chamber. Lowering is continued, until the bracket on the viscometer aligns on the Thermosel. The viscometer is turned on, and set to operate at a shear rate, which leads to a torque reading in the range of 40 to 60 percent of the total torque capacity, based on the rpm output of the viscometer. A reading is taken every minute for about 15 minutes, or until the values stabilize, at which point, a final reading is recorded. This method can also be used to measure the viscosity of a tackifier (at 160℃) , or the viscosity of a wax (at 135℃) .HMA Fiber TearFiber Tear (FT) is measured as a function of temperature, using a BOPP film laminated onto a corrugated cardboard as the substrate. The adhesive composition is heated to 177℃, and is applied onto pre-cut, substrate strips of the following dimensions: “1.0 in x 1.2 in (25 mm x about 30 mm) ” or “1.0 in x 1.0 in (25 mm x 25 mm) . ” The adhesive is applied, running lengthwise, at about a 0.2 in (5 mm) wide strip (located in the middle of the strip) , and is drawn down with a spatula. An adhesive bead weight is about 2 g / m. Then a second strip is applied within two seconds and held, with moderate hand pressure, for five seconds to laminate, and form a test sample. The bond area is “0.2 in x 1 inch, ” and the bond area is located in the middle of the strip.Each prepared test sample is conditioned at room temperature for 24 hours and then conditioned at a test temperatures (-20℃, 0℃, 23℃ or 60℃) for at least 24 hours. Then each test sample is pulled apart at the conditioning test temperature. Each bond is tested immediately, after the conditioning period ended. The bond is torn by inserting the blade of a spatula under one corner to fold up the corner of one of the strips. The bond is then placed on a horizontal surface, with the side with the folded corner faced up. With the laminate held as near as possible to the source of heating or cooling, in order to maintain the conditioning temperature, the folded corner is manually pulled as rapidly, as possible, at roughly a 45 to 90 degree angle, relative to the test sample’s lengthwise axis, to tear the adhesive bond. The percent of torn fiber (or Fiber Tear (FT) ) , within the bond area, is estimated visually. For each composition, the FT test is repeated on five test samples for each test temperature. The average FT of the five samples is reported.Differential Scanning Calorimetry (DSC)Differential Scanning Calorimetry (DSC) , as discussed below, is used to measure Tm, Tc, Tg and crystallinity in ethylene-based (PE) samples and propylene-based (PP) samples, unless noted otherwise. Each sample (0.5 g) is compression molded into a film, at 25000 psi, 190℃, for 10–15 seconds. About 5 to 8 mg of film sample is weighed and placed in a DSC pan. The lid is crimped on the pan to ensure a closed atmosphere. The sample pan is placed in a DSC cell, and then heated, at a rate of approximately 10℃ / min, to a temperature of 180℃ for PE (230℃ for PP) . The sample is kept at this temperature for three minutes. Then the sample is cooled at a rate of 10℃ / min to -90℃ for PE (-60℃ for PP) , and kept isothermally at that temperature for three minutes. The sample is next heated at a rate of 10℃ / min, until complete melting (second heat) . Unless otherwise stated, the melting point (Tm) and the glass transition temperature (Tg) of each polymer sample are determined from the second heat curve, and the crystallization temperature (Tc) is determined from the first cooling curve. The Tg and the respective peak temperature for the Tm are noted. The percent crystallinity can be calculated by dividing the heat of fusion (Hf) , determined from the second heat curve, by a theoretical heat of fusion of 292 J / g for PE (165 J / g for PP) , and multiplying this quantity by 100 (for example, %cryst. = (Hf / 292 J / g) x 100 (for PE) ) .DensityThe density of a polymer is measured by preparing the polymer sample according to ASTM D 1928, and then measuring the density according to ASTM D792, Method B, within one hour of sample pressing.Gel Permeation Chromatography -Ethylene-based PolymersThe chromatographic system consists of a PolymerChar GPC-IR (Valencia, Spain) high temperature GPC chromatograph, equipped with an internal infra-red detector (IR5) . The autosampler oven compartment is set at 160℃, and the column compartment is set at 150℃. The columns are four AGILENT “Mixed A” 30 cm, 20-micron linear mixed-bed columns. The chromatographic solvent is 1, 2, 4-trichlorobenzene, which contains 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 g / mol, and which are arranged in six “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 dissolved at 80℃, with gentle agitation, 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) ) : Mpolyethylene=A× (Mpolystyrene) B (EQ1) , where M is the molecular weight, A has a value of 0.4315 and B is equal to 1.0.A fifth order polynomial is used to fit the respective polyethylene-equivalent calibration points. A small adjustment to A (from approximately 0.375 to 0.445) is made to correct for column resolution and band-broadening effects, such that linear homopolymer polyethylene standard is obtained at 120,000 Mw.The total plate count of the GPC column set is performed with decane (prepared at “0.04 g in 50 milliliters” of TCB, and dissolved for 20 minutes with gentle agitation. ) The plate count (Equation 2) and symmetry (Equation 3) are measured on a 200 microliter injection according to the following equations:where RV is the retention volume in milliliters, the peak width is in milliliters, the peak max is the maximum height of the peak, and 1 / 2 height is 1 / 2 height of the peak maximum; andwhere RV is the retention volume in milliliters, and the peak width is in milliliters, Peak max is the maximum position of the peak, one tenth height is 1 / 10 height of the peak maximum, and where rear peak refers to the peak tail at later retention volumes than the peak max, and where front peak refers to the peak front at earlier retention volumes than the peak max. The plate count for the chromatographic system should be greater than 18,000, and symmetry should be between 0.98 and 1.22.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 (contains 200 ppm BHT) is added to a pre nitrogen-sparged, septa-capped vial, via the PolymerChar high temperature autosampler. The samples are dissolved for two hours at 160℃ 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 4-6, using PolymerChar GPCOneTM 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. Equations 4-6 are as follows:and In order to monitor the deviations over time, a flowrate marker (decane) is 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 within the 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. To facilitate the highest accuracy of a RV measurement of the flow marker peak, a least-squares fitting routine is used to fit the peak of the flow marker concentration chromatogram to a quadratic equation. The first derivative of the quadratic equation is then used to solve for the true peak position. After calibrating the system, based on a flow marker peak, the effective flowrate (with respect to the narrow standards calibration) is calculated as Equation 7:Flowrate (effective) = Flowrate (nominal) * (RV (FM Calibrated) / RV (FM Sample) ) (EQ7) . Processing of the flow marker peak is done via the PolymerChar GPCOneTM Software.Acceptable flowrate correction is such that the effective flowrate is within + / -0.7%of the nominal flowrate.Melt IndexThe melt index (I2) of an ethylene-based polymer is measured in accordance with ASTM D-1238, condition 190℃ / 2.16 kg, unless otherwise noted. The melt flow rate (MFR) of a propylene-based polymer is measured in accordance with ASTM D-1238, condition 230℃ / 2.16 kg.EXPERIMENTALReagents and PolymersReagents and polymers are shown in Table 1.Table 1: Reagents and Polymers*Note, the equation “MI = [3.6126 (10 (log (η) -6.6928) / -1.1363) -9.3185] , where η (cP or mPa·s) = melt viscosity at 350°F (177℃) ” can be used to calculate melt index (2.16 kg, 190℃) for the AFFINITY Grades 1900, 1950 and 1000R.
