Abstract
Description
Background Technology
[0001] Silicone / polyolefin (Si-POE) blends and graft copolymers are widely used in many applications, where the characteristics of silicon impart modified surface properties (reduced coefficient of friction or COF) or moisture-curing functionality to the material. Silicones are blended into a variety of ethylene-based polymers to impart improved tactile properties. Silicone-modified low-density polyethylene (LDPE) materials, formed by direct copolymerization of ethylene with silicon monomers in high-pressure processes, are used in wire and cable applications. Silicone functional groups are also added to linear low-density polyethylene (LLDPE) materials via reactive extrusion, using peroxide grafting of silane monomers such as, for example, vinyltriethoxysilane. Although many examples of these physical blends and reactive extrusion grafting techniques are practiced today, these materials are limited in terms of the final properties related to the blend properties of the material. It is assumed that true Si-POE hybrids offer several advantages, including enhanced surface modification, improved adhesion, alternative crosslinking mechanisms, and the potential benefit of imparting controllable crystallinity to silicone products. Specifically, there is a need for an efficient and economical method to prepare Si-modified polymers (including random copolymers and block copolymers) using olefin-based polymers and silicone sources.
[0002] International publication WO 2012 / 103080 discloses a method for preparing polyolefin-polysiloxane block copolymers, comprising contacting a polyolefin-aluminum compound with an acyclic polysiloxane or cyclic siloxane monomer under effective coupling conditions, in such a manner as to obtain the polyolefin-polysiloxane block copolymer. Such block copolymers comprise polyolefin blocks directly covalently bonded to polysiloxane blocks, wherein the polyolefin blocks comprise the polyolefin-aluminum compound's polyolefin moiety, and the polysiloxane blocks comprise at least a portion of the acyclic polysiloxane. See claim 1. The coupling reaction involves chain scission of the polysiloxane or cyclic polysiloxane and is a relatively slow reaction.
[0003] The United States published formula (I), namely A, in document 2022 / 0073658. 1 L 1 L 2 A 2 Telechelic polyolefin and its preparation method are disclosed in this reference. The method includes: 1) combining raw materials comprising (A) a monomer component, (B) a chain transfer agent component, and (C) a catalyst component comprising a main catalyst to form a solution, and polymerizing (A) a monomer component in the solution at a concentration greater than 10 mol% to less than or equal to 99 mol%; 2) heating the solution; and 3) recovering the product containing the telechelic polyolefin. The (B) chain transfer agent component comprises Al(CH2CH(Y) 2A 2 )3 organoaluminum compounds, in which Y 2 Each time it appears, it is independently hydrogen or C1 to C2. 30 hydrocarbon group; and A 2 Each occurrence is independently a hydrocarbon group containing a hindered double bond. See claim 12. The telechelic polyolefin can be chemically modified, such as by grafting (e.g., by using maleic anhydride (MAH), silane, glycidyl methacrylate or other grafting agents), halogenation, amination, sulfonation or other chemical modifications. See paragraph

[0004] JJ Eisch et al., Stereospecific Reductive Alkylation of Acetylenes by Successive Hydralumination and Carbodemetalation, J. Org. Chem., 1976, 41, 2214-2215, disclose the stereospecific cis-hydralumination of acetylene and the alkylation of the resulting vinylalane aluminate complex. See page 2214. Direct hydralumination of monosubstituted or disubstituted acetylenes is disclosed, providing a convenient and direct route to prepare stereodisubstituted and trisubstituted alkenes, respectively. The disadvantages are as follows: (1) the hydralumination rate of some disubstituted acetylenes is slow; (2) a mixture of positional isomers is produced when R is not equivalent to R'; and (3) RHC=CR'Al(i-C4H9)2 is contaminated by a small amount of RC=C-A1R2' formed by the metallization of terminal alkynes by alkylaluminum. Trimethylsilyl derivatives of monosubstituted acetylene can also be hydroaluminized. See page 2214.
[0005] PR Jones et al., Silaethylene Intermediates from alpha-Lithiosilanes. 2. Reactions with Chlorosilanes and 1,3-Butadiene, 1977, J. Am. Chem. Soc., 99(26), 8447-8451, disclose the formation of silane intermediates by eliminating lithium chloride from alpha-lithium chlorosilanes under appropriate experimental conditions. The reaction of tert-butyllithium with vinyldimethylchlorosilane in a hydrocarbon solvent at low temperature is disclosed to produce cis- and trans-1,1,3,3-tetramethyl-2,4-dineoptyl-1,3-disilcyclobutane in high yields. When this reaction is carried out in the presence of 1,3-butadiene, distinct [2+2] and [2+4] cycloadditions are generated by the reaction of the silane intermediate with butadiene. One of them is 1,1-dimethyl-2-neopentyl-3-vinylsilcyclobutane, which is a compound that cannot be formed by adding α-lithium chlorosilane to butadiene and then cyclizing it. See abstract.
[0006] PR Jones et al., alpha-Lithiosilanes. 4. Silaethylene Cycloadditions with Conjugated Dienes, J. Am. Chem. Soc. 1980, 102, 4970-4973, disclose the reaction of vinyldimethyl-chlorosilanes with tert-butyllithium in the presence of several conjugated dienes. The following dienes: 1,3-butadiene; 2,3-dimethyl-1,3-butadiene; cyclopentadiene; and anthracene; generate cycloadditions of silylene intermediates in hydrocarbon solvents. The presence of tetrahydrofuran in the reaction mixture inhibits the formation of cycloadditions and favors the formation of 1,3-disilacyclobutane. No cycloadditions of 2,5-dimethylfuran were obtained. This reference discloses lithium chloride elimination in hydrocarbon solvents to give silylene intermediates, while addition reactions in THF or in the presence of strong Lewis bases yield α-lithium silanes, and products resulting from their coupling reactions. See abstract.
[0007] N. Petzetakis et al., in their paper "Synthesis of Well Defined Polyethylene-Polydimethylsiloxane-Polyethylene Triblock Copolymers by Diimide-Based Hydrogenation of Polybutadiene Blocks," Macromolecules, 2014, 47, 4151-4159, disclosed a route for synthesizing well-defined polyethylene-b-polydimethylsiloxane-b-polyethylene (EDE) triblock copolymers. The precursors for poly(1,4-butadiene)-b-polydimethylsiloxane-b-poly(1,4-butadiene) (BDB) copolymers were synthesized via anionic polymerization followed by diimide-based hydrogenation. Under standard hydrogenation conditions, the siloxane bonds underwent breakage, leading to significant degradation of the PDMS blocks. This reference discloses the reaction conditions for avoiding PDMS degradation using optimal hydrogenation conditions. See abstract.
[0008] US Patent 3,691,257 discloses the synthesis of polyolefin-siloxane block copolymers using living anionic polymerization (see abstract). These methods typically employ butadiene or isoprene, which must then be hydrogenated to obtain the polyolefin equivalent. The monomers available for anionic polymerization are very limited, typically styrene or butadiene. Therefore, a typical approach to preparing “polyolefin-like” block copolymers is to prepare polybutadiene segments and then remove the unsaturation through hydrogenation. Anionic polymerization is less efficient and more expensive for the production of these block copolymers. Anionic polymerization is generally inefficient and requires lower temperatures and longer reaction times.

[0232] Test methods
[0233] Gas chromatography-mass spectrometry (GC / MS)
[0234] Tandem gas chromatography / low-resolution mass spectrometry using electron collisional ionization (EI) was performed at 70 eV on an Agilent Technologies 6890N series gas chromatograph equipped with an Agilent Technologies 5975 inert XL mass selective detector and an Agilent Technologies capillary column (HP1MS, 15 m × 0.25 mm, 0.25 μm). The following conditions (programmed method) were used: a) oven equilibration time of 0.5 min; b) oven equilibration at 50 °C at the start of analysis, followed by temperature ramping to 200 °C at 25 °C / min and holding at 200 °C for 5 min; c) run time of 11 min.

[0237] Gel permeation chromatography
[0238] Composition of conventional GPC
[0239] The chromatographic system consisted of a PolymerChar GPC-IR (Valencia, Spain) high-temperature GPC chromatograph equipped with an internal IR5 infrared detector (IR5). The autosampler oven chamber was set to 160°C, and the column chamber to 150°C. Four Agilent "Mixed A" 30 cm, 20 μm linear mixed-bed columns were used. The chromatographic solvent was 1,2,4-trichlorobenzene containing 200 ppm of butylated hydroxytoluene (BHT). The solvent source was nitrogen injection. The injection volume was 200 μL, and the flow rate was 1.0 mL / min.
[0240] The calibration of the GPC column was performed using 21 narrow molecular weight distribution polystyrene standards ranging from 580 g / mol to 8,400,000 g / mol, arranged in six “mixture” solutions with at least ten-fold intervals between individual molecular weights. The standards were purchased from Agilent Technologies. For molecular weights equal to or greater than 1,000,000, polystyrene standards were prepared using “0.025 g in 50 mL of solvent”, and for molecular weights less than 1,000,000, polystyrene standards were prepared using “0.05 g in 50 mL of solvent”. The polystyrene standards were pre-dissolved at 80°C with gentle stirring for 30 minutes, then cooled, and the “room temperature solution” was transferred to a 160°C autosampler dissolution oven for cooling for 30 minutes. The peak molecular weights of the polystyrene standards were converted to polyethylene molecular weights using Equation 1 (e.g., Williams and Ward, J. Polym. Sci., Polym. Let., 6, 621 (1968)). , where M is the molecular weight, A has a value of 0.424 and B equals 1.0. A fifth-order polynomial is used to fit the calibration point for the corresponding polyethylene equivalent.
[0241] Total plate counts were performed on the GPC column array using decane, which was introduced into the blank sample via a micropump controlled by a PolymerChar GPC-IR system. For four Agilent "Mixed Type A" 30 cm, 20 μm linear mixed-bed columns, the plate count of the chromatographic system should be greater than 18,000. Samples were prepared semi-automatically using PolymerChar "InstrumentControl" software, with a target sample weight of 2 mg / mL, and the solvent (containing 200 ppm BHT) was added to a pre-bubbled, septum-capped vial using a PolymerChar high-temperature autosampler. The sample was dissolved at 160°C for 2 hours with "low-speed" shaking.
[0242] To monitor deviations over time, a flow rate marker (decane) was introduced into each sample via a micropump controlled by a PolymerChar GPC-IR system. This flow rate marker (FM) was used to linearly correct the pump flow rate (nominal flow rate) for each sample by comparing the RV (RV(FM sample)) of the corresponding decane peak within the sample with the RV (RV(FM calibrated)) of the decane peak within the narrow standard calibration. It was then assumed that any variation in the decane marker peak time was linearly related to the flow rate (effective flow rate) throughout the run. After calibration based on the flow marker peak, the effective flow rate (relative to the narrow standard calibration) was calculated according to Equation 2. (via PolymerChar GPCOne)™ The software processes the flow marker peaks. Acceptable flow rate correction ensures that the effective flow rate is within + / - 0.5% of the nominal flow rate.
[0243] IR5 GPC Octene Composition Calibration
[0244] Calibration for quantitative dispensing of the IR5 detector was performed using at least ten ethylene-based polymer standards (octene as a comonomer), which were characterized by narrow short-chain branching (SCB or CH3) distribution and known comonomer content (e.g., by means of...). 13 The standards (measured by C NMR, Qiu et al., Anal. Chem. 2009, 81, 8585−8589) were prepared from a single reactor using a single-point metallocene catalyst in a solution process (polyethylene homopolymer and ethylene / octene copolymer). These standards range from homopolymers (0 SCB / 1000 total C) to approximately 40 SCB / 1000 total C, where total C = carbon in the main chain + carbon in the branches. Each standard has a weight-average molecular weight of 36,000 g / mol to 126,000 g / mol as measured by GPC. Each standard has a molecular weight distribution (Mw / Mn) of 2.0 to 2.5. The polymer properties of the SCB standards are shown in Table A.
[0245]
[0246] For each of the “SCB” standards, calculate the “IR5 area ratio” (or “IR5 area ratio”) of the “area response of the IR5 methyl channel sensor minus the baseline” to the “area response of the IR5 measurement channel sensor minus the baseline”. 甲基通道面积 / IR5 测量通道面积 (e.g., standard filters and filter wheels supplied via PolymerChar: part number IR5_FWM01SS includes parts as part of a GPC-IR instrument). The linear fit between the SCB frequency and the "IR5 area ratio" is constructed in the form of the following Equation 3: Where A0 is the intercept of SCB / 1000 total C at zero "IR5 area ratio", and A1 is the slope of "SCB / 1000 total C" versus "IR5 area ratio" and represents the increase of SCB / 1000 total C as a function of "IR5 area ratio". For narrow PDI and narrow SCBD standard materials, the IR5 area ratio is equal to the IR5 height ratio.
[0247] The superposition of GPC curves can be performed using commercially available software, such as software available for the chromatography system or Excel software; or by other methods known in the art.
[0248] NMR (13C and 29Si)
[0249] 13 C NMR and 29 Si NMR spectra were collected individually using a Bruker 600MHz Avance III HD system equipped with a 10mm multinuclear, helium NMR cryopreservation probe. A standard zgig pulse sequence was used. Polymer samples were prepared by adding approximately 2.6g of a 50 / 50 mixture of tetrachloroethane-d2 / o-dichlorobenzene containing 0.025M chromium triacetylacetonate (relaxant) to 0.2g of the polymer in a 10mm NMR tube. The samples were dissolved and homogenized by heating the tube and its contents to 150°C. Data were acquired using 320 scans per data file at a 7.3-second pulse repetition delay and a sample temperature of 120°C. More NMR samples and parameters are detailed in Z.

[0303]
[0304] In a drying oven under a nitrogen atmosphere, 1,3-divinyltetramethyldisiloxane (0.254 g, 1.364 mmol) and trioctylaluminum (0.1 g, 0.273 mmol) were dissolved in 5 mL of decane in a vial, and the solution was heated to 130 °C (temperature of the heating block).

Figure 1 These product peaks are consistent with fragments of products formed by the addition of octane to one or two vinyl groups. Samples taken at 1 hour (see...) Figure 1 This shows the growth of the product peak.

[0313] Study 2 - Polymer Synthesis - Solution Method
[0314] Example 3
[0315] The preparation of the polyethylene-PDMS linear block polymer is shown in Scheme 6 below.
[0316]
[0317] In a drying oven (nitrogen atmosphere), 10 ml of ISOPAR-E solvent, 1.8 μmol of Co-Cat 1, and 0.22 mmol of TEA were added to a 40 ml vial equipped with a stir bar. The vial was capped with a diaphragm-lined cap and placed in a heating block. The vial was connected to the C2 (ethylene) line and slowly purged through a needle using this line. Once the vial reached 100 °C (as indicated by the temperature of the heating block), the main catalyst 1 [(E)-((2,6-diisopropylphenyl)(2-methyl-3-(octylimino)butane-2-yl)amino)trimethylhafnium], 1.5 μmol in 0.2 ml of ISOPAR-E] was injected into the vial, and the purging needle was removed to maintain the total pressure at 12 psig (as determined by the pressure gauge on the ethylene line). The reaction was maintained for 20 minutes. Afterward, the ethylene line was removed, and a portion of the solution was removed and allowed to precipitate in MeOH to obtain pure polyethylene. Add 1 mL of DMS-V05 to the remaining solution in the vial and heat the resulting solution at 130 °C for 30 min, then precipitate the reaction product in MeOH. Filter both the polyethylene and the reaction product and dry them under vacuum. Analyze each product by GPC. The compositional GPC overlay plot is shown in... Figure 3As shown in the image.
[0318] exist Figure 3 In the diagram, regarding the "dW / dLogM" y-axis, when Log M = 3.00, the narrower upper curve represents polyethylene (PE), the next lower curve represents the reaction products containing PE-PDMS and PE, and the wider lower curve represents DMS-V05.
[0319] 29 Si NMR spectrum in Figure 4 The 13C NMR spectrum is shown in Figure 5 As shown in the image. Based on 29 Si NMR, based on the Si-CH2-P / Si-CH=CH2 ratio, shows that approximately 40% of the double bonds in the "Si-C=C" region are converted to Si-P (where P is a polyethylene polymer) (compare the Si peak intensity in the Si NMR spectrum). Based on 13C NMR, based on the Si-CH2-P / Si-CH=CH2 ratio, approximately 47% of the double bonds in the "Si-C=C" region are converted to Si-P (compare the carbon peak intensity in the 13C NMR spectrum). These NMR results each indicate that the reaction proceeded as described in Scheme 6 above.

[0324] exist Figure 6 In the diagram, regarding the "dW / dLogM" y-axis, when Log M=3.00, the narrower upper curve is the curve for polyethylene (PE), the next lower "bimodal" curve is the curve for the reaction products containing PE-PDMS and PE, and the wider lower curve is the curve for VMS-T11.
[0325] As discussed above, in the two polymerizations of Examples 3 and 4, for each reaction, the GPC curves of the block copolymers were superimposed on the starting siloxane and polyethylene samples (obtained before the addition of the siloxane). Clearly, the block copolymers exhibited higher MW fractions compared to the base polyethylene, especially in Example 4, which showed bimodal MWD, indicating the formation of some block copolymers.
[0326] GC-mass spectrometry of the 3-reaction product (Zn) was studied.
[0327] Example 5
[0328] The reaction of diethylzinc (DEZ) with 1,3-divinyltetramethyldisiloxane (DVTMDS) - see Scheme 8.
[0329]
[0330] In a drying oven under a nitrogen atmosphere, 1,3-divinyltetramethyldisiloxane (0.543 g, 2.9 mmol) and trioctylaluminum (0.3 mL, 2.9 mmol) were dissolved in 5 mL of decane in a vial and heated at 150 °C for 20 min. The resulting sample was hydrolyzed (with MeOH) and analyzed by GC / MS. The GC / MS results indicated the presence of the insertion product (m / z = 201) according to Scheme 8, as shown below. The corresponding GC / MS peak chromatogram is shown below. Figure 7 As shown.
