[Technical Field]
[0001] Cross-reference of related applications This application claims priority to U.S. Provisional Patent Application No. 63 / 127,350, filed on 18 December 2020, which is incorporated herein by reference in its entirety. [Background technology]
[0002] The catalytic production of olefin block copolymers (OBCs) via chain shuttle technology has resulted in differentiated materials such as INFUSE Olefin Block Copolymers and INTUNE Olefin Block Copolymers. Such copolymers are typically produced from ethylene and alpha-olefins. The use of chain shuttle technology for producing styrene-based block interpolymers presents an attractive route to high-value polymers using continuous solution polymerization processes. High-value styrene-based polymers, such as styrene-ethylene / butene-styrene (SEBS), are produced in batch processes via anionic polymerization initiated by organolithium compounds. This costly polymerization involves the continuous addition of monomers, followed by an expensive hydrogenation step. There is a need for chain shuttle technology for producing ethylene / vinyl ylene block and triblock interpolymers using double-reactor continuous solution polymerization.

Ed. 2014, 53, 4638-4641, "Isoprene-Styrene Chain Shuttling Copolymerization Mediated by a Lanthanide Half-Sandwich Complex and a Lanthanidocene: Straightforward Access to a New Type of Thermoplastic Elastomers," discloses chain shuttle polymerization of isoprene and styrene using n-butylethyl-magnesium, a lanthanide half-sandwich complex, and lanthanidocene. The resulting multiblock structure has alternating hard (styrene-enriched) and soft (isoprene-enriched) segments.
[0004] U.S. Patent Application Publication No. 2014 / 0088276 (Manufacturing Method for Multidimensional Polymer, and Multidimensional Polyme) discloses the polymerization of stereocontrolled (syndiotactic) block copolymers of styrene-type monomers and conjugated dienes such as isoprene or butadiene by chain shuttle technique and coordination chain transfer polymerization. Polymerization is carried out in the presence of a first catalyst and a second catalyst. The first and second catalysts each independently contain: a) a group 3 metal atom or lanthanide metal atom, e.g., Sc; b) a Cp-type ligand containing a substituted or unsubstituted cyclopentadienyl derivative; c) a monoanionic ligand; and d) a neutral Lewis base.
[0005] U.S. Patent No. 8,623,976 (Polymerization Catalyst Compositions Containing Metallocene Complexes and the Polymers Produced by Using the Same) is as follows: a) i) Group 3 metal atoms or lanthanide metal atoms, e.g., Sc, ii) Cp of substituted or unsubstituted cyclopentadienyl derivatives * Ligand, iii) Monoanionic ligands, iv) A metallocene complex containing a neutral Lewis base, b) Disclosed is a catalyst composition comprising an ionic compound of a non-coordinating anion and a cation, such as tetrakis(penta-fluorophenyl)borate. The catalyst composition is used to polymerize various polymers, such as ethylene / styrene copolymers (see Examples 11-17). The polymerized styrene may be in a syndiotactic form.

Ed. 2011, 50, 12012-12015, Chain-Shuttling Polymerization at Two Different Scandium Sites: Regio and Stereospecific "One-Pot" Block Copolymerization of Styrene, Isoprene, and Butadiene disclose chain-shutling polymerization of styrene, isoprene, and butadiene using two different catalysts and a chain-shutling agent (triisobutylaluminum, TIBA). These catalysts exhibit different monomer selectivity and stereoselectivity in the presence of TIBA, resulting in region-specific and stereospecific copolymerization of styrene, isoprene, and butadiene.

Polyethylene / polypropylene copolymers are grown from dual-head zinc species using coordination chain transfer polymerization, followed by the addition of an anionic initiator (e.g., Me3SiCH2Li-(pmdeta)) and styrene monomer. Coordination chain transfer polymerization is carried out in the presence of a transition metal (e.g., Zr or Hf) complex. Thus, anionic polymerization is used to grow polystyrene-terminated blocks that exhibit no stereoregularity.

This preparation method involves preparing an intermediate by coordination polymerization of an olefin monomer using a transition metal catalyst, and then inserting a portion of the styrene monomer into the intermediate by anionic polymerization. Examples of transition metal catalysts include Zr metal compounds represented by chemical formulas 6A and 6B, each of which is shown in the document (see paragraphs

[0052] Ethylene / vinyl alloy blocks and triblock interpolymers Examples of ethylene / vinylarene diblock interpolymer formation and ethylene / vinylarene triblock interpolymer formation are schematically shown in Figures 1A and 1B, respectively. According to these figures, ethylene / alpha-olefin random copolymer "blocks" directly bonded to organometallic reagents, such as zinc or aluminum-based chain shuttling agents (CSAs) or dual-headed chain shuttling agents (DHCSAs), are produced in a first reactor using a first transition metal catalyst. These polymeric zinc or polymeric aluminum species obtained in the first reactor are transferred to a second reactor. The lifetime of the first transition metal catalyst (metal complex) is spent until the contents of the first reactor are transferred to the second reactor. In the second reactor, styrene, ethylene, and optionally alpha-olefins are polymerized in the presence of a second transition metal catalyst to produce random styrene / ethylene interpolymer "blocks." Next, polymeric zinc or polymeric aluminum species from the first reactor undergo chain shuttle with the second reactor catalyst to grow styrene / ethylene random "blocks" on the ethylene / alpha-olefin polymer chain, producing the desired diblock (Figure 1A) or triblock (Figure 1B) interpolymer. The two types of random blocks (vinylarene-enriched, i.e., hard blocks, and vinylarene-deficient, i.e., soft blocks) have different chemical or physical properties. Each block has two or more monomer species distributed substantially randomly within the block.
[0053] As discussed, the ethylene / vinyl arene block and triblock interpolymers preferably contain two chemically distinct regions (referred to as "blocks") that are linked linearly. In one embodiment, the blocks differ in the amount or type of incorporated comonomers, density, degree of crystallinity, type or degree of stereoregularity (isotactic or syndiotactic), or any other chemical or physical properties. Compared to conventional block interpolymers, including interpolymers produced by continuous monomer addition, fluid catalysts, or anionic polymerization techniques, the ethylene / vinyl arene block and triblock interpolymers of the present invention are characterized by unique distributions of both polymer polydispersity (PDI or Mw / Mn or MWD), block length distribution, and / or block number distribution, due to the effect of the shuttling agent in combination with multiple catalysts used for their preparation in a dual reactor.
[0054] Vinylarene monomer Vinylarene monomers are aromatic monomers, including, but not limited to, aromatic vinyl compounds such as mono- or polyalkylstyrenes (including styrene, o-methylstyrene, m-methylstyrene, p-methylstyrene, o,p-dimethylstyrene, o-ethylstyrene, m-ethylstyrene, and p-ethylstyrene), and functional group-containing derivatives such as o-chlorostyrene, m-chlorostyrene, p-chlorostyrene, divinylbenzene, 3-phenylpropene, 4-phenylpropene, and α-methylstyrene. However, the monomers are polymerizable under the conditions in which they are used.
[0055] Chain shuttle agent (CSA) The term "chain shuttle agent (CSA)" refers to a compound or mixture of compounds that can cause polymeryl exchange between at least two active catalytic sites of a catalyst included in polymerization conditions. That is, the movement of polymer fragments occurs from one or more of the active catalytic sites, or from both. A CSA can perform chain transfer, for example, between an "AP (soft block) catalyst" and an "AR (hard block) catalyst."
[0056] Suitable shuttle agents include, but are not limited to, group 1, 2, 12, or 13 metal compounds or complexes comprising hydrocarbyl-substituted aluminum, gallium, or zinc compounds containing at least one substituted or unsubstituted hydrocarbyl group, preferably each hydrocarbyl group containing 1 to 12 carbon atoms, and their reaction products with a proton source. Preferred hydrocarbyl groups are alkyl groups, preferably linear or branched C2-C8 alkyl groups. Suitable chain shuttle agents include, but are not limited to, trialkylaluminum and dialkylzinc compounds, particularly triethylaluminum, tri(isopropyl)aluminum, tri(isobutyl)aluminum, tri(n-hexyl)aluminum, tri(n-octyl)aluminum, triethylgallium, or diethylzinc. See U.S. Patent No. 8,710,143 (incorporated herein by reference).
[0057] Dual-head chain shuttle agents (e.g., Al-DHCSA and AlZn-DHCSA) are also suitable agents. The following chemical formula applies to dual-head chain shuttle agents: R1-[M-R2-] n -The structure M-R1 is an example, but is not limited to it, where R1 and R2 are each independently hydrocarbons containing 1 to 20 carbon atoms, n≧1, and M=Zn. See also International Publication No. 2018 / 064546 and U.S. Patent No. 8,501,885 (both incorporated herein by reference).

[0126] Test method Gel permeation chromatography (conventional type) The chromatography system consisted of a PolymerChar GPC-IR (Valencia, Spain) high-temperature GPC chromatograph equipped with an internal IR5 infrared detector (IR5). The autosampler oven compartment was set to 160 degrees Celsius, and the column compartment to 150 degrees Celsius. The column consisted of four AGILENT "Mixed A" 30 cm, 20 micron linear mixed-bed columns. The chromatography solvent was 1,2,4-trichlorobenzene containing 200 ppm butylated hydroxytoluene (BHT). The solvent source was spurged with nitrogen. The injection volume used was 200 microliters, and the flow rate was 1.0 ml / min.
[0127] Calibration of the GPC column set was performed using 21 polystyrene standards with narrow molecular weight distributions ranging from 580 to 8,400,000, placed in six "cocktail" mixtures with at least a 10-fold gap between individual molecular weights. The standards were purchased from Agilent Technologies. Polystyrene standards were prepared using 0.025 grams per 50 ml of solvent for molecular weights above 1,000,000, and 0.05 grams per 50 ml of solvent for molecular weights below 1,000,000. The polystyrene standards were dissolved at 80 degrees Celsius for 30 minutes with gentle stirring. The peak molecular weights of the polystyrene standards were converted to polyethylene molecular weights using Formula 1 (as described in Williams and Ward, J. Polym. Sci., Polym. Let., 6, 621 (1968)). M ポリエチレン =A × (M ポリスチレン ) B (Formula 1) (In the formula, M is the molecular weight, A has a value of 0.4315, and B is equal to 1.0).
[0128] A quintic polynomial was used to fit the respective polyethylene equivalent calibration points. A slight adjustment (approximately 0.375 to 0.445) was made for A to correct the column resolution and band expansion effect so that the linear homopolymer polyethylene standard material could be obtained at 120,000 Mw. The total plate count of the GPC column set was performed using decane (prepared with 0.04 g in 50 ml of TCB and dissolved for 20 minutes with gentle stirring). Plate count (Equation 2) and symmetry (Equation 3) were measured using a 200 microliter injection according to the following formulas.

[0131] Samples were prepared semi-automatically using PolymerChar "Instrument Control" software. The sample (target weight 2 mg / ml) and solvent (containing 200 ppm BHT) were added to septum-capped vials via a PolymerChar high-temperature automated sampler before nitrogen purging. The samples were dissolved at 160°C for 2 hours under "low-speed" shaking.

Equations 4-6 are as follows:

[0134] To monitor deviations over time, a flow rate marker (decane) was introduced to 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 (apparent flow rate) for each sample by RV-matching each decane peak (RV(FM sample)) within the sample to that of the decane peak in the narrow standard calibration (RV(FM calibrated)). It was then hypothesized that any temporal changes in the decane marker peaks were related to a linear shift in the overall flow rate (effective flow rate). To facilitate the highest accuracy of RV measurements of the flow rate marker peaks, a least-squares fitting routine was used to fit the peaks of the flow rate marker concentration chromatogram to a quadratic equation. The first derivative of the quadratic equation was then used to determine the true peak position. After calibrating the system based on the flow rate marker peaks, the effective flow rate (with respect to the narrow standard calibration) was calculated as shown in Equation 7: Effective flow rate = Apparent flow rate. * (RV(FM calibrated) / RV(FM sample))(Equation 7). Flow marker peak processing was performed via PolymerChar GPCOne® software. Acceptable flow correction was set so that the effective flow rate was within + / - 0.7% of the apparent flow rate.
[0135] Melt Index The melt index (I2) of ethylene-based polymers was measured according to ASTM D-1238, under conditions of 190°C / 2.16 kg. The melt flow rate (MFR) of propylene-based polymers was measured according to ASTM D-1238, under conditions of 230°C / 2.16 kg.

[0137] Differential Scanning Calorimetry (DSC) Differential scanning calorimetry (DSC) was used to measure the Tm, Tc, Tg, and crystallinity of ethylene (PE) and propylene (PS) samples. Approximately 5–8 mg of polymer sample was weighed and placed in a DSC dish. The lid was pressed onto the pan to ensure a closed atmosphere. Unless otherwise specified, the sample dish was placed in the DSC cell and then heated at 10°C / min to 180°C for PE (300°C for PS). The sample was held at this temperature for 3 minutes. The sample was then cooled at a rate of 10°C / min to -90°C for PE (-90°C for PS) and held isothermally at that temperature for 3 minutes. Next, the sample was heated at a rate of 10°C / min until completely melted (second heating). Unless otherwise specified, the melting point (T) of each polymer was measured. m ) and glass transition temperature (T g The crystallization temperature (T) is determined from the second thermal curve. c ) was determined from the first cooling curve. m (Peak temperature) and T g The following was recorded. The heat of fusion (H) was determined from the second heat curve. f The degree of crystallinity can be calculated by dividing (Hf / 292J / g) by the theoretical heat of fusion (292J / g for PE, 53J / g for PS) and multiplying this amount by 100 (for example, degree of crystallinity % = (Hf / 292J / g) × 100 (for PE)).
[0138] 13 C NMR Each sample was prepared by adding approximately 2.7 g of stock solvent to 0.2 g of sample (polymer, polymer composition, or metal complex) in a 10 mm NMR tube. The stock solvent was tetrachloroethane-d2 containing 0.025 M chromium acetylacetonate (relaxant). The sample was capped and sealed with Teflon tape. The sample was dissolved and homogenized by heating the tube and its contents at 130°C to 135°C. Data were acquired using a Bruker 600 MHz spectrometer equipped with a Bruker high-temperature cryoprobe. Data was acquired using a pulse repetition delay of 7.3 seconds (6-second delay + 1.3-second acquisition time), a flip angle of 90 degrees, and reverse gate decoupling at a sample temperature of 120°C. All measurements were performed on non-rotating samples in lock mode. The sample was homogenized immediately before insertion into a heated (125°C) NMR sample exchanger and thermally equilibrated in the probe for 7 minutes before data acquisition.
[0139] For the analysis of each sample (polymer or polymer composition), the B1 carbon (quaternary carbon on the aromatic ring) signal of 145.0–147.7 ppm was used as the styrene contribution, and the molar amount of polymerization monomer was calculated as follows (S = styrene, E = ethylene). Smol = integral value (145.0~147.7 ppm). Emol = (integral value (20.0~48.0 ppm) - 2) * Smol) / 2 Smol%=100 * Smol / (Smol+Emol) Emol% = 100 - Smol%

The molar amount of polymerization monomer was calculated as follows (S=styrene, E=ethylene, O=octene). Smol = Integral value (124.0~148.0 ppm) / 6 Omol = (Integral value (22.0~23.5 ppm) + Integral value (31.5~32.7 ppm)) / 2 Emol = (integral value (11.8~48.0 ppm) - 2) * Smol-8 * Omol) / 2 Smol%=100 * Smol / (Smol+Omol+Emol) 0 mol% = 100 * Omol / (Smol+Omol+Emol) Emol% = 100 - Smol% - 0mol%.

To prevent oxidation, the sample was purged by passing N2 through the solvent for approximately 5 minutes via a pipette inserted into the tube. The sample container was capped and sealed with Teflon tape. The sample was heated to 115°C and vortexed to ensure homogeneity. ¹H NMR was performed on a Bruker AVANCE 600 MHz spectrometer equipped with a Bruker high-temperature cryoprobe at a sample temperature of 120°C. ¹H NMR was performed with a ZG pulse, 4 scans, SWH 10,000 Hz, AQ 1.64 s, and D1 14 s.

[0162] II. Screening Catalysts PPR screening of Sc complexes (CAT B) against hard blocks. To demonstrate the feasibility of styrene polymerization activity and the chain-shutting ability of polymerization catalysts, a Parallel Pressure Reactor (PPR) system was employed. The activity and molecular weight of a given styrene polymerization catalyst in relation to the amount of chain-shutting agent (CSA) added were investigated. The chain-shutting agents examined were diethylzinc (DEZ) and triethylaluminum (TEA), respectively, as models for polymeric alkylzinc species and polymeric alkylaluminum species. Al-Zn DHCSA was also used. The PPR screening conditions were as follows: [ISOPAR-E + MMAO-3A + T] + (styrene + CSA + amines, bis(hydrogenated tallow alkyl)methyl, tetrakis(pentafluorophenyl)borate (1-) + catalyst). Catalyst input amount = 0.25 μmole. MMAO-3A input amount = 5 μmole; T = 105°C, t = 15 min, [styrene] = 2.1 M (in toluene).
[0163] CAT B was screened in PPR for its styrene polymerization ability in the presence of various model chain-shutting agents. Figure 4 demonstrates that CAT B exhibits high efficiency for styrene polymerization (without CSA) and that its catalytic activity is unaffected by the addition of TEA (third circle from the top at CSA=25 μmole, third and fourth circles from the top at CSA=100 μmole) or Al-Zn DHCSA (top two merged circles at CSA=25 μmole, and top two circles at CSA=100 μmole). For this particular study, catalytic activity was low in the presence of DEZ (two merged lower circles at CSA=25 μmole, and two merged lower circles at CSA=100 μmole). The data in Figure 5 shows that the addition of CSA results in a decrease in molecular weight, indicating that the catalyst is involved in effective chain shuttle action. Al-Zn DHCSA is represented by two upper circles at CSA=25μmole and two upper circles at CSA=100μmole. TEA is represented by two merged lower circles at CSA=25μmole and two merged lower circles at CSA=100μmole.
[0164] Table 1 further illustrates the effect of adding 100 μmole of CSA to styrene polymerization by CAT B at 105°C. Furthermore, styrene polymerization by CAT B was tested in the presence of 1-octene. The PPR screening conditions were as follows: T=105°C, catalyst input=0.25 μmole, [styrene]=2.1 M (in toluene), t=15 min. As shown in Table 1, the catalytic activity and molecular weight were not affected by the addition of 1-octene, indicating that CAT B is compatible with the residual alpha-olefin monomer transferred from the first reactor to the second reactor. This data demonstrates that catalyst CAT B satisfies the above-mentioned desired second reactor (R2) catalyst criteria (a)~c)) (see "Detailed Description of the Invention").
[0165] [Table 1] M = Catalyst metal (Sc)
[0166] Sc catalyst: Chain shuttle experiment for CAT B Toluene (final volume 8 mL), styrene (1 mL), and a magnetic stirring rod were placed in a glass vial. CAT B (5 μmol), amines, bis(hydrogenated tallow alkyl)methyl, tetrakis(pentafluorophenyl)borate (1-) (1.2 equivalents (equivalent to CAT B)), and either TEA or DEZ (0, 25 μmol, or 100 μmol) were sequentially added to the solution. This mixture was heated at 100°C for 1 hour and then cooled before quenching in methanol. The polymer was collected by filtration and dried under vacuum. GPC results are shown in Table 6. The results are also shown in Table 2. Compared to sPS-1, a chain shuttle process occurs, as indicated by the decrease in molecular weight and MWD (Mw / Mn) in the presence of DEZ or TEA.

[0168] III. Analysis of vinylarene enrichment (hard block) and vinylarene deficiency (soft block) Batch reactor polymerization setup The batch reactor setup consisted of a 600 mL per reactor controlled by a process control system. The reactor featured an electrically heated jacket, an internal cooling coil for temperature control, and an electrically heated trace transfer line between the reactor and the reactor dump pot. Three feeds were available, with the option of introducing solvents or monomers from removable 1-liter (50 mL) cylinders. These cylinders were placed in an inert (N2) glove box, and the contents were transferred to the reactor via nitrogen injection. Catalyst components and chain shuttles were prepared in an inert glove box and transferred to the reactor via nitrogen transfer from a 50 mL cylinder. A "1-octene cylinder" was filled from the purification plant feed. Ethylene was supplied from Airgas as a high-purity grade. For further purification, 1-octene and ethylene were passed through an in-line bed of activated alumina, a 13x molecular sieve, and Q5 material. High-pressure nitrogen for catalyst injection and purging was of ultra-high-purity grade. The styrene was degassed, and the inhibitor was removed by passing the styrene feed through a neutral alumina plug immediately before adding it to the reactor.
[0169] Ethylene, 1-octene, styrene polymerization: Reactivity of CAT B (vinylarene enrichment) Degassed anhydrous toluene was added to a 600 mL per reactor from a nitrogen-pressurized solvent cylinder using a mass flow meter, and the reactor stirrer was set to 450 rpm. Styrene was injected through a high-pressure nitrogen-pressurized cylinder. At the time of use, a preset amount of 1-octene was added to the reactor from a nitrogen-pressurized cylinder using a flow meter. When the reactor reached the starting temperature setpoint of 120°C, a preset amount of ethylene was added to the reactor using a flow meter, followed by the addition of the activated catalyst solution. Cp *A catalyst solution was prepared by adding a pre-prepared toluene solution of ScR2 (CAT B) (usually added at a rate of 22 μmol Sc), a 0.006 M solution of amines, bis(hydrogenated tallow alkyl)methyl, a tetrakis(pentafluorophenyl)-borate(1-) activator (1.0-1.2 equivalents) in toluene, and a 0.05 M solution of MMAO-3A (10 equivalents) in toluene. Each "equivalent" is relative to 1 equivalent of CAT B.
[0170] The ethylene flow was started at 200 mg / min while controlling the overall reactor pressure to a programmed setpoint throughout the desired run time of 10 minutes. After the mixing time, the stirrer was stopped and the contents of the reactor were transferred to a dump pot. The contents of the pot were poured into methanol and the mixture was stirred. The polymer precipitate was filtered and dried in a vacuum oven at 130°C for 6 hours. The polymerization conditions and polymer properties are shown in Table 3 below. See also Table 4. In Tables 3 and 4, interpolymers AR1 to AR12 represent, for example, the vinylarene-enriched (hard block) (AR) segment, stereoregularity, Tm, and Tg of the polymerized vinylarene in the monomer composition of the ethylene / octene / -styrene diblock or triblock interpolymer, respectively.

[0172] [Table 4] a Determined by 13C NMR, each mol% is based on the total number of moles of polymerization monomers in the interpolymer (representing vinylarene enrichment (hard block)).
[0173] Ethylene, 1-octene, styrene polymerization: Reactivity of CAT A (vinylarene deficiency) Degassed anhydrous toluene was added to a 600 mL per reactor from a nitrogen-pressurized solvent cylinder using a mass flow meter, and the reactor stirrer was set to 450 rpm. Styrene was injected through a cylinder pressurized with high-pressure nitrogen. A predetermined amount of 1-octene was added to the reactor from a nitrogen-pressurized cylinder using a flow meter. When the reactor reached the starting temperature setpoint of 120°C, a predetermined amount of ethylene was added to the reactor using a flow meter, followed by the addition of the activated catalyst solution. The catalyst solution was prepared by adding a pre-prepared toluene solution of CAT A catalyst, a 0.006 M solution of amines, bis(hydrogenated tallow alkyl)methyl, tetrakis(pentafluorophenyl)-borate(1-) activator (1.0-1.2 equivalents) in toluene, and a 0.05 M solution of MMAO-3A in toluene (10 equivalents). Each "equivalent" is relative to 1 equivalent of CAT A.
[0174] The ethylene flow was started at 200 mg / min while controlling the overall reactor pressure to a programmed setpoint over a desired run time of 10 minutes. After the mixing time, the stirrer was stopped and the contents of the reactor were transferred to a dump pot. The contents of the pot were poured into methanol and the mixture was stirred. The polymer precipitate was filtered and dried in a vacuum oven at 130°C for 6 hours. The polymerization conditions and polymer properties are shown in Table 5 below. See also Table 6. Interpolymers AP1 to AP11 in Table 6 represent, for example, the vinylarene-deficient (soft block) (AP) segment of the ethylene / octene / styrene diblock or triblock interpolymer in the monomer composition, the stereoregularity of the polymerized vinylarene, Tm, and Tg, respectively.
[0175] [Table 5] General: Catalyst = 6-8 μmol CAT A, 1.2 × "amines, bis(hydrogenated tallow alkyl)methyl, tetrakis(pentafluorophenyl)borate (1-)", 10 × MMAO, T=120℃, t=10 min, V=600 mL.
[0176] [Table 6] Note: The mol% values for styrene in the table were calculated to include only the styrene present in E / O / S terpolymers, assuming the absence of back-to-back styrene. This is based on the observation that CAT A does not polymerize styrene under homopolymerization conditions. Attactic polystyrene was assumed to arise from thermally generated PS. a Each mol% based on the total number of moles of polymerization monomers in the interpolymer represents a vinylarene deficiency (soft block).
[0177] IV. Double catalytic polymerization using chain shuttle agents Batch reactor polymerization setup (dual-per-reactor) - solution polymerization The polymerization setup consisted of two reactors, namely a 600 mL per reactor (reactor 1, R1) and a 2.0 L per reactor (reactor 2, R2), each controlled by a process control system. Both reactors were equipped with electrically heated jackets, internal cooling coils for temperature control, and electrically heated trace transfer lines between reactors and from each reactor to the reactor dump pot. Three feeds were available for either reactor, with the option of supplying solvent or monomer from a removable 1 L sample cylinder. The 1 L cylinders were placed in an inert (N2) glove box, and the contents were transferred to either reactor via nitrogen injection. Catalyst components and chain shuttles were prepared in an inert glove box and transferred to each reactor via nitrogen transfer from a 50 mL cylinder. ISOPAR-E and 1-octene cylinders were filled from the purification plant feed. Ethylene was supplied from Airgas as high-purity grade. For further purification, 1-octene and ethylene were passed through an in-line bed of activated alumina, a 13x molecular sieve, and Q5 material. High-pressure nitrogen was used for catalyst injection and purging, resulting in ultra-high purity grade.
[0178] Batch reactor-solution polymerization-composition containing Triblock 2 A 600 mL Par reactor (R1 (first reactor)) was filled with a solution of Al-DHCSA (1.5 mL, 578 μmol) in 4 mL of ISOPAR-E by high-pressure nitrogen injection. ISOPAR-E (121.4 g) was added to R1 from a nitrogen-pressurized solvent cylinder using a mass flow meter, and the reactor stirrer was set to 450 rpm. A predetermined amount of 1-octene (20.4 g) was added to R1 from a nitrogen-pressurized cylinder using a flow meter. When the reactor reached the starting temperature setpoint of 120 °C, a predetermined amount of ethylene (7.1 g) was added to the reactor using a flow meter, followed by the addition of the activated catalyst solution. A catalyst solution was prepared by adding 0.25 mL of a 0.005 M solution of CAT A in toluene, 0.25 mL of a 0.006 M solution of amines, bis(hydrogenated tallow alkyl)methyl, and tetrakis(pentafluorophenyl)borate(1-) in toluene, and 0.25 mL of a 0.05 M solution of MMAO-3A in toluene to a vial containing 4 mL of toluene.
[0179] Throughout the desired run time of 10 minutes (for R1), the ethylene flow was started at 200 mg / min while controlling the overall reactor pressure to 192.7 psig. During the run time of R1, 200 mL of toluene was filled into the "2.0 L Parr" reactor (R2, the second reactor) via a small cylinder pressurized with nitrogen. The stirrer in R2 was set to 450 rpm, and the starting temperature setpoint for R2 was set to 120°C. When the run time (10 minutes) in R1 was complete, the stirrers in both reactors (R1 and R2) were stopped. R1 was pressurized with nitrogen to transfer its contents to R2 via a preheated line. CAT A (lifetime less than 10 minutes) was consumed when this catalyst entered the second reactor.
[0180] After transferring the contents, the stirrer in R2 was restarted. Styrene monomer (5 mL, 0.044 mol) was injected into R2 via a small cylinder pressurized with nitrogen, and immediately afterward, the activated catalyst solution in 200 mL of toluene was added. A catalyst solution was prepared by adding Sc complex CAT B in 45 μmol of toluene, a 0.006 M solution of amines, bis(hydrogenated tallow alkyl)methyl, tetrakis(penta-fluorophenyl)borate (1-) (0.5 μmol) in 0.083 mL of toluene, and a 0.05 M solution of MMAO-3A (5 μmol) in 0.100 mL of toluene to a vial containing 4 mL of toluene. After the addition of the catalyst, exothermic reaction was observed. The contents of R2 were stirred at 120 °C for a run time of 1 hour (for R2). After the reaction time, the stirrer for R2 was stopped, and the contents of R2 were transferred to a dump pot. The contents of the pot were poured into methanol and stirred overnight. The polymer precipitate (composition containing ethylene / octene / styrene triblocker polymer (Triblock 2)) was filtered and dried in a vacuum oven at 130 °C for 6 hours (yield 11.6 g). NMR profiles were shown in Figure 7 (1H NMR) and Figure 8 (13C NMR). The results are shown in NMR. Based on the peak integration in Figure 7, the composition contained 30% by weight of polymerized styrene, based on the weight of the composition. The peaks representing phenyl C-1 (δ145.50), Sαα (δ43.35), and Tββ (δ40.61) of the syndiotactic polystyrene block are shown in Figure 8.
[0181] Additional polymer composition The additional polymer compositions are described below. The polymerization conditions and polymer composition properties are listed in Tables 7 and 8.
[0182] Triblock 1 (a composition containing ethylene / octene / styrene triblock 1 terpolymer) was polymerized using the process described above for Triblock 2, with the following modifications: A 600 mL par reactor (R1) was filled with a solution of Al-DHCSA (1.5 mL, 690 μmol) in 4 mL of ISOPAR-E by pressurized nitrogen injection. An ethylene flow of 200 mg / min was started, while controlling the total reactor pressure to 192.7 psig over a desired run time of 30 minutes (for R1). Styrene monomer (5 mL, 0.690 mmol) was injected into R2 via a small nitrogen-pressurized cylinder, and immediately thereafter, an activated catalyst solution in 200 mL of toluene was added. A catalyst solution was prepared by adding a 0.0021 M solution of Sc complex CAT B (0.5 μmol) in 0.240 mL of toluene, a 0.006 M solution of amines, bis(hydrogenated tallow alkyl)methyl, tetrakis(pentafluorophenyl)-borate (1-) (0.5 μmol) in 0.083 mL of toluene, and a 0.05 M solution of MMAO-3A (5 μmol) in 0.100 mL of toluene to a vial containing 4 mL of toluene. The polymer precipitate (composition containing the triblock) was filtered and dried in a vacuum oven at 130°C for 6 hours (yield 13.0 g). To detect AR-AP bonding (vinylarene enriched (hard block) - vinylarene deficient (soft block) S), a Malvern 305a HT with a triple detector (dRI, DV, LS) connected to DiscovIR™ (FT IR) and PDA (UV-Vis) was used. GPC was employed. The GPC data is shown in Figure 9 [HT GPC dRI / UV dual detector response to dual-batch reactor run, showing unbound PS, unbound EO, and bound PS]. As can be seen in Figure 9, the formation of block interpolymers appears as a "bound PS" peak.
[0183] Triblock 3 (a composition containing ethylene / octene / styrene triblock co-polymer) was prepared according to the process for Triblock 2 shown above, except for the modifications described in Table 7 below. Diblock 1 (a composition containing ethylene / octene / styrene diblock terpolymer) was prepared according to the process for Triblock 2 shown above, except for the use of TEA (400 μmole) as the CSA and the modifications described in Table 7 below. Diblock 2 (a composition containing ethylene / octene / styrene diblock terpolymer) was prepared according to the process for Triblock 2 shown above, except for the use of DEZ (100 μmole) as the CSA and the modifications described in Table 7 below.
[0184] Instead of CSA, two in-reactor blends (IB-1 and IB-2), which were ethylene / octene random copolymer and syndiotactic styrene polymer, respectively, were prepared using the same process as used for Triblock 2 described above, without pre-injection with Al-DHCSA, except for the modifications described in Table 7 below.

[0187] GPC research Refer to the GPC procedure in the section on test methods above. A PolymerChar (Valencia, Spain) high-temperature gel permeation chromatography system consisting of an infrared concentration / composition detector (IR-5) was used to determine MW and MWD. The support solvent was 1,2,4-trichlorobenzene (TCB). The autosampler and detector compartments were operated at 160°C, and the column compartment was operated at 150°C. The GPC column set was calibrated using 21 polystyrene standards with narrow molecular weight distributions. The GPC profiles are shown in Figures 10a and 10b. The GPC results are shown in Tables 7 and 9. For the molecular weight distribution of the double reactor polymer, the values are the polystyrene equivalent molecular weights. As can be seen in Table 9, compositions containing triblock polymers have a broader MWD compared to the in-reactor blend (IB-1).
[0188] [Table 9]
[0189] Tensile Test Research The mechanical properties of the two polymer samples are shown in Table 10. See also Figure 11. The samples exhibit elastic recovery behavior.
[0190] [Table 10]
[0191] V. Atactic Polystyrene (aPs): CAT C Polymerization Experiment: Toluene (final volume 8 mL), styrene (1 mL), and a magnetic stirring rod were placed in a glass vial. CAT C (5 umol), amines, bis(hydrogenated tallow alkyl)methyl, tetrakis(pentafluorophenyl)borate (1-) (1.2 equivalents), and either TEA or DEZ (0, 25, or 100 umol) were sequentially added to the solution. This mixture was heated at 100°C for 1 hour and then cooled before quenching in methanol. The polymer was collected by filtration and dried under vacuum. The results are shown in Table 11. The GPC profile is shown in Figure 12. These results indicate that a chain shuttle process occurs, as shown by the decrease in molecular weight and MWD (Mw / Mn) in the presence of DEZ or TEA.
[0192] [Table 11]
[0193] VI.Ti complex PPR screening of Ti complexes (CAT D, CAT E, and CAT F) As described below, a parallel pressure reactor (PPR) system was employed to demonstrate the feasibility of styrene polymerization activity and chain shuttle of each polymerization catalyst. The activity and molecular weight of given styrene polymerization catalyst candidates in relation to the amount of CSA input were investigated. The CSAs examined were diethylzinc (DEZ, 25 μmole or 100 μmole) and triethylaluminum (TEA, 25 μmole or 100 μmole), respectively, as models of polymeric alkylzinc species and polymeric aluminum species. The PPR screening conditions were as follows: [ISOPAR-E + MMAO-3A + T] + (styrene + CSA + "amine, bis(hydrogenated tallow alkyl)methyl, tetrakis(pentafluorophenyl)borate (1-) + catalyst). Catalyst input = 0.25 μmole. MMAO-3A input = 50 μmol. T = 75°C and 105°C, t = 15 min, [styrene] = 2.1 M (in toluene).
[0194] CAT D was screened by PPR for its styrene polymerization ability in the presence of the mentioned chain shuttle agent. Figure 13 demonstrates that the addition of CSA results in a decrease in molecular weight, indicating that the catalyst is involved in effective chain shuttle action. CAT D shows relatively low efficiency for styrene polymerization. CAT E was screened by PPR for its styrene polymerization ability in the presence of the mentioned chain shuttle agent. Figure 14 demonstrates that the addition of CSA results in a decrease in molecular weight, indicating that the catalyst is involved in effective chain shuttle action. CAT E shows relatively low efficiency for styrene polymerization. CAT F was screened by PPR for its styrene polymerization ability in the presence of the mentioned chain shuttle agent. Figure 15 demonstrates that the addition of CSA results in a decrease in molecular weight, indicating that the catalyst is involved in effective chain shuttle action. CAT F shows relatively low efficiency for styrene polymerization. This application also relates to the following aspects.
