[0047] Similarly, the content of the first monomer unit 1B in the raw polymer may be appropriately set depending on the desired function of the polymer, but may be, for example, 0.01 to 30 mol% relative to the total 100 mol% of the moles of each monomer unit contained in the raw polymer (100 mol% in total of the first monomer unit, second monomer unit, and other monomer units). The content of the first monomer unit 1B may be, for example, 0.01, 0.1, 1, 5, 10, 15, 20, 25, or 30 mol%, or may be within a range between any two of the numerical values ​​exemplified here. For example, it may be 0, or within a range between any two of the numerical values ​​exemplified here.

[0048] The content of the first monomer unit 1C in the raw polymer may be appropriately set depending on the desired function of the polymer, and may be, for example, 0.01 to 30 mol% relative to 100 mol% in total of the number of moles of each monomer unit contained in the raw polymer (100 mol% in total of the first monomer unit, second monomer unit, and other monomer units). The content of the first monomer unit 1C may be, for example, 0.01, 0.1, 1, 5, 10, 15, 20, 25, or 30 mol%, or may be within a range between any two of the values ​​exemplified here.

[0049] The total content of first monomer units 1B and 1C (content of monomer units containing an allene structure) in the raw polymer may be set appropriately depending on the desired function of the polymer, and may be, for example, 0.01 to 30 mol% of the total of 100 mol% of the moles of each monomer unit contained in the raw polymer (100 mol% of the first monomer units, second monomer units, and other monomer units). The total content of first monomer units 1B and 1C may be, for example, 0.01, 0.1, 1, 5, 10, 15, 20, 25, or 30 mol%, and may be within a range between any two of the values ​​exemplified here.

[0050] By adjusting the amount of each monomer unit, the type, number, and amount of functional groups can be changed in a polymer obtained by introducing a specific functional group into each first monomer unit. The presence or absence and content of each monomer unit can be controlled by adjusting the production conditions of the raw polymer, for example, by adjusting the temperature and pressure during polymerization. For example, increasing the temperature during polymerization can increase the amount of monomer units (first monomer units 1B and 1C) bonded that contain an allene structure. Furthermore, decreasing the pressure during polymerization can decrease the amount of first monomer units 1A, 1B, and 1C bonded. The presence or absence and content of each monomer unit can be controlled, for example, by １３ In the C-NMR spectrum, the amount of each functional group can be calculated based on the presence or absence of a peak appearing at a specific peak position, the peak intensity, the peak area, the amount of each functional group, etc. Alternatively, the amount of each functional group can be confirmed by infrared spectroscopy (IR).

[0051] 1.1.4 Characteristics of the raw polymer The raw polymer is measured in deuterated chloroform solvent. １３ In the C-NMR spectrum, a peak β may be present in the range of 190 to 220 ppm. Here, peak β may be a peak derived from an allene structure. Peak β is believed to be associated with the first monomer unit 1B and / or 1C described above. Peak β may be observed, for example, at 190, 192, 194, 196, 198, 200, 202, 204, 206, 208, 210, 212, 214, 216, 218, or 220 ppm, and may be within a range between any two of the values ​​exemplified herein. Note that multiple peaks β may be observed, and for example, two peaks (peak β1 and peak β2) may be observed. Peak β1 may be observed, for example, at 190, 192, 194, 196, 198, or 200 ppm, and may be within a range between any two of the values ​​exemplified herein. Peak β2 can be observed, for example, at 200, 202, 204, 206, 208, 210, 212, 214, 216, 218, or 220 ppm, and may be within a range between any two of the values ​​exemplified here.

[0052] The raw material polymer according to one embodiment of the present invention may have a peak α in the range of 60 to 90 ppm in a C-NMR spectrum measured in a deuterated chloroform solvent. Here, peak α may be a peak derived from an acetylene structure. Peak α is believed to be associated with the first monomer unit 1A described above. Peak α may be observed, for example, at 60, 62, 64, 66, 68, 70, 72, 74, 75, 76, 78, 80, 82, 84, 86, 88, or 90 ppm, or may be within a range between any two of the values ​​exemplified herein. Multiple peaks α may be observed, or two peaks (peak α1 and peak α2) may be observed. Peak α1 may be observed, for example, at 60, 62, 64, 66, 68, 70, 72, 74, 75, or 76 ppm, or may be within a range between any two of the values ​​exemplified herein. Peak α1 can be a peak based on a triple bond carbon to which hydrogen is bonded. Peak α2 can be observed, for example, at 70, 72, 74, 75, greater than 75, 76, 78, 80, 82, 84, 86, 88, or 90 ppm, or may be within a range between any two of the values ​​exemplified here. Peak α2 can be a peak based on a triple bond carbon to which carbon is bonded.

[0053] In addition, in the C-NMR spectrum of the raw material polymer measured in deuterated chloroform, the peak intensity or peak area of ​​peak β relative to the peak intensity or peak area of ​​peak α is preferably 1% to 15%. The peak intensity or peak area of ​​peak β relative to the peak intensity or peak area of ​​peak α can be, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15%, and may be within a range between any two of the values ​​exemplified here.

[0054] The presence or absence of peaks in the 13C-NMR spectrum and their peak intensities (peak areas) can be confirmed by the methods described in the Examples or methods similar thereto.

[0055] It is preferred that the starting polymer exhibits a single glass transition in a differential scanning calorimetry curve obtained by subjecting the starting polymer to differential scanning calorimetry (DSC).

[0056] The observation of a single glass transition means that there is one step shift in the baseline in the differential scanning calorimetry curve obtained by differential scanning calorimetry (DSC). Furthermore, when one step shift in the baseline is observed in the differential scanning calorimetry curve, the copolymer is considered to be neither a block copolymer nor a mixture of homopolymers, but a random copolymer.

[0057] The differential scanning calorimetry curve can be obtained as described in the Examples. The glass transition temperature can be the midpoint glass transition temperature (Tmg) measured in accordance with JIS K 7121.

[0058] The glass transition temperature can be adjusted by, in particular, the glass transition temperatures of the homopolymers of the first monomer, the second monomer, and the other monomers, and the blending ratios thereof. When the theoretical glass transition temperature of the raw material polymer is Tp [K], the glass transition temperature of the raw material polymer is preferably Tp±10% [K] (i.e., Tp±0.1×Tp [K]). Here, when the raw material polymer is composed of monomer units derived from n types of monomers, Tp [K] can be such that the following formula (1) is satisfied when T1 [K] is the glass transition temperature of a homopolymer of a first monomer, C1 is the mass fraction of the copolymerization amount of the first monomer unit relative to 100 parts by mass of the raw material polymer, T2 [K] is the glass transition temperature of a homopolymer of a second monomer, C2 is the mass fraction of the copolymerization amount of the second monomer unit relative to 100 parts by mass of the raw material polymer, Tk [K] is the glass transition temperature of a homopolymer of a kth monomer, and Ck is the mass fraction of the copolymerization amount of the kth monomer unit relative to 100 parts by mass of the raw material polymer. n can be an integer of 2 or greater. Furthermore, C1 + C2 + ... + Cn = 1. The above formula is based on the FOX formula. The glass transition temperature is, for example, -100, -90, -80, -70, -60, -50, -40, -30, -20, -10, 0, 10, 20, 30, 35, 40, 45, 50, 55, 60, 65, 70, 80, 90, or 100°C, and may be within a range between any two of the values ​​exemplified here. A raw polymer satisfying the above glass transition temperature requirements can be obtained by adjusting the production method for the raw polymer, particularly the type and amount of each raw monomer, and the polymerization conditions.

[0059] The raw polymer may be a random copolymer, an alternating copolymer, a block copolymer, a graft copolymer, etc. The raw polymer may be a random copolymer, and the fact that it is a random copolymer can be confirmed by observing a single glass transition between the glass transition temperatures of the homopolymers constituting the raw polymer in a differential scanning calorimetry curve, and when the raw polymer is composed of a first monomer unit and a second monomer unit, it can be confirmed by observing a single glass transition between the glass transition temperature of the homopolymer of the first monomer and the glass transition temperature of the homopolymer of the second monomer.

[0060] The weight-average molecular weight of the raw polymer can be 1,000 to 2,000,000. The weight-average molecular weight of the raw polymer can be, for example, 1,000, 5,000, 10,000, 50,000, 100,000, 500,000, 1,000,000, or 2,000,000, and may be within a range between any two of the values ​​exemplified here. The weight-average molecular weight can be a polystyrene-equivalent value measured by gel permeation chromatography (GPC), and can be, for example, a value measured under the measurement conditions described below. Apparatus name: HLC-8320 (manufactured by Tosoh Corporation) Column: Three TSKgel GMHHR-H columns in series Temperature: 40°C Detection: Differential refractive index Solvent: Tetrahydrofuran Calibration curve: Can be prepared using standard polystyrene (PS).

[0061] The raw polymer can be a starting point for producing a polymer that can have various substituents. For example, the copolymer can be used as a raw material for the Huisgen reaction with an azide-based compound. For example, the acetylene group contained in the raw polymer and the azide-based compound having a substituent R (R-N ３ ) and a compound having a triazole ring with a substituent R can be obtained by the Huisgen reaction, and the target compound can be obtained with high efficiency and high accuracy while suppressing the amount of by-products produced.

In the polymerization process for the raw polymer according to one embodiment of the present invention, when the total amount of the raw material monomers used in the polymerization process is 100 parts by mass, the amount of monomers other than the first monomer and the second monomer may be 50 parts by mass or less. For example, the amount may be 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, or 50 parts by mass, or may be within a range between any two of the values ​​exemplified herein.

[0072] The polymerization step can be radical polymerization of the first monomer and the second monomer using an initiator.

These initiators may be used alone or in combination.

[0074] In the polymerization process, first, the second monomer, initiator, and chain transfer agent are added to a solvent, and the gas phase is replaced with an inert gas such as nitrogen. The first monomer is then pumped with the inert gas and heated under pressure to polymerize. The polymerization conditions can be adjusted depending on the type of raw material monomer and the desired polymer properties. For example, the pressure can be 0.005 to 0.05 MPaG. The pressure can be, for example, 0.005, 0.010, 0.015, 0.020, 0.025, 0.030, 0.035, 0.040, 0.045, or 0.050 MPaG, or can be within a range between any two of the values ​​exemplified here.

[0084] 1.3 Reaction Conditions In a reaction process according to one embodiment of the present invention, an acetylene group contained in a raw polymer is reacted with an azide group-containing compound to obtain a triazole skeleton-containing polymer by the Huisgen reaction. The Huisgen reaction is known as click chemistry, in which azide and acetylene groups react only with each other gently and are stable against nucleophiles, electrophiles, and solvents commonly used in standard reaction conditions. Furthermore, the resulting triazole ring-containing polymer is also stable, allowing these to react quickly and reliably to obtain the desired triazole skeleton-containing polymer.

[0085] In the reaction step, at least some of the acetylene groups contained in the raw polymer may be reacted with an azide group-containing compound, and the resulting triazole skeleton-containing polymer may have first monomer units 1A. In the reaction step, of 100 mol % of the first monomer units 1A contained in the raw polymer, 1 to 100 mol % of the acetylene groups contained in the first monomer units 1A may be reacted with the azide group-containing compound to form a triazole skeleton. In the reaction step, of 100 mol % of the first monomer units 1A contained in the raw polymer, the amount of the first monomer units 1A reacted with the azide group-containing compound may be 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 99, or 100 mol %, and may be within a range between any two of the values ​​exemplified here. The reaction rate of the first monomer unit 1A can be controlled by adjusting the conditions of the Huisgen reaction, and the reaction can be made highly efficient with high accuracy. The presence and amount of acetylene groups and first monomer units 1A in the triazole skeleton-containing polymer after the reaction can be confirmed by the same method as the above-mentioned method for confirming the presence and amount of acetylene groups and first monomer units 1A in the raw material polymer.

[0086] When the raw polymer has an allene structure (when it has first monomer unit 1B and / or first monomer unit 1C), the resulting triazole skeleton-containing polymer may have an allene structure or may have first monomer unit 1B and / or first monomer unit 1C. In the reaction step, at least a portion of the allene structure contained in the raw polymer may be converted to another structure (e.g., by introducing a functional group). Furthermore, the allene structure contained in the raw polymer may be reacted with any compound (e.g., a compound other than an azide group-containing compound) to use the allene structure as another functionalization site. The allene structure can be converted simultaneously with the Huisgen reaction, or can be converted and functionalized in a separate reaction step before or after the Huisgen reaction to synthesize the triazole skeleton-containing polymer. It is preferable to convert and functionalize the allene structure simultaneously with the Huisgen reaction or before the Huisgen reaction. In the reaction step, of 100 mol % of the first monomer units 1B and 1C contained in the raw polymer, for example, 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 99, or 100 mol % may remain in the triazole skeleton-containing polymer, and may be within a range between any two of the values ​​exemplified here. The remaining ratios of the first monomer units 1B and 1C can be controlled by adjusting the reaction conditions, for example, by adjusting the type and amount of reagents used in the Huisgen reaction.

The content of the first monomer units 1A may be, for example, 0, 0.01, 0.1, 0.5, 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, or 99 mol%, or may be within a range between any two of the values ​​exemplified here.

[0093] Similarly, the content of the first monomer unit 1B in the copolymer may be appropriately set depending on the desired function to be imparted to the polymer, and may be, for example, 0.01 to 30 mol% relative to the total 100 mol% of the number of moles of each monomer unit contained in the copolymer (100 mol% in total of the triazole skeleton-containing monomer unit, the first monomer unit, the second monomer unit, and other monomer units).

[0096] 2.1 Characteristics of the triazole skeleton-containing polymer The triazole skeleton-containing polymer according to one embodiment of the present invention is measured in a deuterated chloroform solvent. １３In the C-NMR spectrum, a peak β may be present in the range of 190 to 220 ppm. Here, peak β may be a peak derived from an allene structure. Peak β is believed to be associated with the first monomer unit 1B and / or 1C described above. Peak β may be observed, for example, at 190, 192, 194, 196, 198, 200, 202, 204, 206, 208, 210, 212, 214, 216, 218, or 220 ppm, or may be within a range between any two of the values ​​exemplified herein. Note that multiple peaks β may be observed, and for example, two peaks (peak β1 and peak β2) may be observed. Peak β1 may be observed, for example, at 190, 192, 194, 196, 198, or 200 ppm, or may be within a range between any two of the values ​​exemplified herein. Peak β2 can be observed, for example, at 200, 202, 204, 206, 208, 210, 212, 214, 216, 218, or 220 ppm, and may be within a range between any two of the values ​​exemplified here.

[0097] The triazole skeleton-containing polymer according to one embodiment of the present invention is measured in a deuterated chloroform solvent. １３In the C-NMR spectrum, peak α may be present in the range of 60 to 90 ppm. Here, peak α may be a peak derived from an acetylene structure. Peak α is considered to be associated with the first monomer unit 1A described above. Peak α may be observed, for example, at 60, 62, 64, 66, 68, 70, 72, 74, 75, 76, 78, 80, 82, 84, 86, 88, or 90 ppm, or may be within a range between any two of the values ​​exemplified herein. Note that multiple peaks α may be observed, or two peaks (peak α1 and peak α2) may be observed. Peak α1 may be observed, for example, at 60, 62, 64, 66, 68, 70, 72, 74, 75, or 76 ppm, or may be within a range between any two of the values ​​exemplified herein. Peak α1 may be a peak derived from a triple-bonded carbon to which hydrogen is bonded. Peak α2 can be observed, for example, at 70, 72, 74, greater than 75, 76, 78, 80, 82, 84, 86, 88, or 90 ppm, or may be within a range between any two of the values ​​exemplified here. １３ The presence or absence of a peak in the C-NMR spectrum can be confirmed by the method described in the Examples or a method equivalent thereto. Peak α2 can be a peak based on a triple bond carbon bonded to carbon.

[0098] In the triazole skeleton-containing polymer according to one embodiment of the present invention, a plurality of glass transitions may be observed, but a single glass transition is preferably observed, in a differential scanning calorimetry curve obtained by subjecting the triazole skeleton-containing polymer to differential scanning calorimetry (DSC).

[0099] The observation of a single glass transition means that there is one step shift in the baseline in the differential scanning calorimetry curve obtained by differential scanning calorimetry (DSC). Furthermore, when one step shift in the baseline is observed in the differential scanning calorimetry curve, the copolymer is considered to be neither a block copolymer nor a mixture of homopolymers, but a random copolymer.

[0100] The method for obtaining a differential scanning calorimetry curve can be as described in the Examples. The glass transition temperature can be the midpoint glass transition temperature (Tmg) measured in accordance with JIS K 7121. The glass transition temperature can be obtained by adjusting the method for producing the triazole skeleton-containing polymer, particularly the types and amounts of each raw material monomer and polymer, and the reaction conditions. The glass transition temperature of the triazole skeleton-containing polymer is preferably Tp±10% [K] (i.e., Tp±0.1 × Tp [K]), where Tp [K] is the theoretical glass transition temperature of the triazole skeleton-containing polymer. Here, when the triazole skeleton-containing polymer is composed of monomer units derived from n types of monomers, Tp [K] can be such that the following formula (1) is satisfied when T1 [K] is the glass transition temperature of a homopolymer composed of the triazole skeleton-containing monomer (a homopolymer of a first monomer reacted with an azide group-containing compound), C1 is the mass fraction of the copolymerization amount of the triazole skeleton-containing monomer unit (the first monomer unit reacted with an azide group-containing compound) relative to 100 parts by mass of the triazole skeleton-containing polymer, T2 [K] is the glass transition temperature of a homopolymer of a second monomer, C2 is the mass fraction of the copolymerization amount of the second monomer unit relative to 100 parts by mass of the triazole skeleton-containing polymer, Tk [K] is the glass transition temperature of a homopolymer of a kth monomer, and Ck is the mass fraction of the copolymerization amount of the kth monomer unit relative to 100 parts by mass of the copolymer. n can be an integer of 2 or greater. Furthermore, C1 + C2 + ... + Cn = 1. The above formula is based on the FOX formula. The glass transition temperature is, for example, -40, -30, -20, -10, 0, 15, 30, 50, 70, 90, 100, 105, 110, 115, or 120°C, and may be within a range between any two of the values ​​exemplified here.

[0101] The triazole skeleton-containing polymer according to one embodiment of the present invention may be a random copolymer, an alternating copolymer, a block copolymer, a graft copolymer, or the like. The triazole skeleton-containing polymer according to one embodiment of the present invention may be a random copolymer, and the fact that it is a random copolymer can be confirmed by the observation of a single glass transition between the glass transition temperatures of the homopolymers constituting the triazole skeleton-containing polymer in a differential scanning calorimetry curve. When the triazole skeleton-containing polymer is composed of a triazole skeleton-containing monomer unit and a second monomer unit, the observation of a single glass transition between the glass transition temperature of the homopolymer of the triazole skeleton-containing monomer unit and the glass transition temperature of the homopolymer of the second monomer can be confirmed. The weight-average molecular weight of the triazole skeleton-containing polymer according to one embodiment of the present invention may be 1,000 to 2,000,000. The weight average molecular weight is, for example, 1,000, 5,000, 10,000, 50,000, 100,000, 500,000, 1,000,000, or 2,000,000, and may be within a range between any two of the values ​​exemplified here.

[0102] 3. Composition A composition according to one embodiment of the present invention contains the triazole skeleton-containing polymer. The reaction solution containing the triazole skeleton-containing polymer obtained by the above production method after the reaction step can be used as a composition according to one embodiment of the present invention. The composition according to one embodiment of the present invention is obtained through the above reaction step, specifically, through the Huisgen reaction, and therefore can reduce unnecessary by-products.

[0103] A method for producing a polymer having a desired structure and functional groups includes, for example, preparing a triazole skeleton-containing compound A, which is a macromonomer having the desired structure and functional groups, a triazole ring, and a polymerizable group, and polymerizing the compound. However, when a triazole skeleton-containing polymer is prepared by such a method, the triazole skeleton-containing compound A may remain in the resulting reaction solution. In a composition according to one embodiment of the present invention, the content of the triazole skeleton-containing compound A relative to 100% by mass of the triazole skeleton-containing polymer may be 5% by mass or less. The content of the triazole skeleton-containing compound A relative to 100% by mass of the triazole skeleton-containing polymer may be, for example, 0, 0.01, 0.05, 0.1, 0.5, 1, 2, 3, 4, or 5% by mass, or may be within a range between any two of the values ​​exemplified here. In a composition according to one embodiment of the present invention, the triazole skeleton-containing compound A relative to 100% by mass of the triazole skeleton-containing polymer may be free of the triazole skeleton-containing compound A. Here, the triazole skeleton-containing compound A may be a compound having a triazole skeleton and a polymerizable group bonded to the triazole skeleton. The triazole skeleton-containing compound A is a compound having R ５ (and R １５ or R ２５ According to the production method according to one embodiment of the present invention, it is possible to reduce unnecessary by-products, and since the triazole skeleton-containing polymer and composition according to one embodiment of the present invention have a low content of unnecessary by-products, it is possible to reduce the effort and cost of the purification step.

[0110] Polystyrene azide was synthesized based on Macromolecules, 2006, 39, 5286-5292. PMMA azide (polymethyl methacrylate azide) was synthesized based on J. Am. Chem. Soc. 2017, 139, 10551-10560. In all of the examples, a triazole skeleton-containing compound A having a triazole skeleton and a polymerizable group bonded to the triazole skeleton was not detected in the resulting reaction solution.

[0111] The obtained raw material monomer and triazole skeleton-containing polymer were １３ The raw polymer was analyzed by C-NMR to determine the content of the first monomer units 1A in the raw polymer and the unreacted amount of the first monomer units 1A remaining in the triazole skeleton-containing polymer. The content of the first monomer units 1A indicates the content of the first monomer units 1A when the total of all monomer units contained in the raw polymer is taken as 100 mol% (i.e., when the total of the first monomer units 1A, 1B, and 1C, and the second monomer units is taken as 100 mol%). The unreacted amount of the first monomer units 1A indicates the remaining amount of the first monomer units (first monomer units 1A, 1B, and 1C) when the total of the triazole skeleton-containing monomer units, the first monomer units (first monomer units 1A, 1B, and 1C), and the second monomer units contained in one molecule of the triazole skeleton-containing polymer is taken as 100 mol%.
