Description

Technical Field

[0001] The invention relates to the technical field of polymer material synthesis, in particular to a polydisulfide polymer material containing a hydroxy ester group and a preparation method thereof. Background Art

[0002] Thioctic acid (TA) is a naturally occurring cyclic sulfide with antioxidant function in animals, and its molecular structure contains cyclic disulfide bonds and carboxyl groups. Lipoic acid can be synthesized through ring-opening polymerization to form poly(thioctic acid) (PTA) with dynamic disulfide bonds in the main chain and carboxyl groups in the side groups. This linear polydisulfide can be depolymerized in a dilute solution of sodium hydroxide and can be reconverted into lipoic acid monomers, which can achieve chemical closed-loop recycling and thus have regeneration. The degradation products of polylipoic acid reduced by disulfide bonds are small molecules with biocompatibility, thus having biodegradability. The carboxyl side groups in polylipoic acid can form coordination bonds, hydrogen bonds, etc., and can also be used as cross-linking points to prepare cross-linked polymers. The unique chemical structure of polylipoic acid gives it many excellent properties, such as cell permeability, processability, ductility, adhesion, etc., and it has broad application prospects in the fields of biomedical materials, smart materials, self-healing materials, recyclable materials, adhesives, electronic devices, etc.

[0003] Polymers composed of natural lipoic acid offer a solution for the development of sustainable materials. However, their inherent weak networks make them difficult to use in engineering materials with high durability and mechanical strength. In the prior art, autocatalytic dual dynamic covalent adaptive networks (CANs) were designed by curing 4,5-epoxycyclohexane-1,2-dicarboxylic acid diglycidyl ester (DGEDC) with lipoic acid and bis(p-aminocyclohexyl)methane (PACM). The resulting DGEDC / TA / PACM thermosets showed good mechanical and thermal properties (T g 145℃, T d,5％289 ° C, tensile strength of 70MPa, Young's modulus of 2.25GPa), which is higher than previous polylipoic acid-based materials. Due to the topological network rearrangement caused by the exchange of disulfide bonds and tertiary amine-catalyzed ester exchange reactions, they can be easily transformed and repaired. In addition, they can be gently degraded and upgraded to polyurethane foams by in-situ foaming [Yaning Ma, Zihan Zhao, Zhiran Zheng, er al. High-performance poly (thioctic acid)-based thermosets featuring upcycling ability for in situfoaming enabled by dual-dynamic networks [J]. Matter 7, 1-13].

[0004] However, there are problems: the polydisulfide containing hydroxy ester groups synthesized by the prior art is not a polymer with a clear molecular weight and molecular chain structure, and the molecular weight of the polydisulfide molecular chain segment in such supramolecular materials is uncontrollable. Summary of the invention

[0022] Embodiment 1:

[0023] See also Figure 1 , which is a schematic diagram of the synthesis route of a polydisulfide polymer material containing a hydroxy ester group. This embodiment provides a method for preparing a polydisulfide polymer material containing a hydroxy ester group, wherein the synthesis substrate of the polymer material is polylipoic acid or lipoic acid-styrene copolymer;

[0024] The preparation method of polylipoic acid comprises the following steps:

[0025] Adding lipoic acid monomer to the first organic solvent at a set molar ratio to obtain a lipoic acid reaction component, dissolving the lipoic acid monomer in the first organic solvent to obtain a lipoic acid monomer solution;

[0026] Adding an initiator to the lipoic acid reaction component according to a set molar ratio, the initiator triggers the lipoic acid monomer to undergo a cationic ring-opening polymerization reaction;

[0027] Adding a reaction terminator to the lipoic acid reaction component after adding an initiator to obtain polylipoic acid;

[0028] The preparation method of thioctic acid-styrene copolymer comprises the following steps:

[0029] Adding thioctic acid monomer and styrene monomer into the second organic solvent according to a set molar ratio to obtain a thioctic acid-styrene reaction component, dissolving the thioctic acid monomer and styrene monomer in the second organic solvent to obtain a thioctic acid-styrene monomer solution;

[0030] Adding an initiator to the lipoic acid-styrene reaction component according to a set molar ratio, the initiator triggering a cationic copolymerization reaction between the lipoic acid monomer and the styrene monomer;

[0031] Adding a reaction terminator to the lipoic acid-styrene reaction component after adding the initiator to obtain a lipoic acid-styrene copolymer;

[0032] The preparation method of the polymer material comprises the following steps:

[0033] After polylipoic acid or lipoic acid-styrene copolymer is mixed with epoxide in the ratio of carboxyl group:epoxy group=200:(1-200), a catalyst is added, and a ring-opening reaction is carried out at 40-160°C for 0.5-4h to obtain a polymer material.

[0034] Furthermore, the preparation method of the polymer material comprises the following steps:

[0035] After removing the solvent from the solution containing the lipoic acid polymer, a lipoic acid polymer elastomer is obtained;

[0036] After mixing the lipoic acid polymer elastomer with the epoxy compound, reacting them in an extruder, a mixer, an injection molding machine or other equipment to obtain a polymer material;

[0037] Wherein, the ratio of lipoic acid polymer elastomer to epoxy compound is carboxyl group:epoxy group=200:(1-200);

[0038] The lipoic acid polymer is polylipoic acid or lipoic acid-styrene copolymer.

[0039] Specifically, the cationic polymerization system has a variety of initiator selections, and the polymerization activity of the monomer can be controlled by factors such as the initiator, polymerization reaction temperature and solvent polarity, and has the characteristics of extremely fast reaction speed and non-termination of the kinetic chain. The method for preparing a polydisulfide polymer material provided by the present invention utilizes a cationic polymerization initiation system to initiate thioctic acid monomers, as well as efficient polymerization of thioctic acid monomers and styrene monomers. The initiation system is diverse, the solution polymerization process is simple, the operation is safe, a single-component initiator or a two-component initiation system composed of an initiator and a co-initiator can be selected, it is easy to prepare, the consumption is small, and it has industrial production feasibility, and polymerization can be carried out in a solution under low or normal temperature conditions. The polylipoic acid prepared by the present invention has excellent properties such as high toughness, self-repairing performance, chemical recyclability, biocompatibility and biodegradability, so the polydisulfide polymer material prepared by the present invention also has the above beneficial properties. The substrate of the polydisulfide polymer material is polylipoic acid or lipoic acid-styrene copolymer prepared by cationic polymerization. The carboxyl groups on the molecular chain are converted into hydroxy ester groups through a derivatization reaction. At the same time, different structures are easily introduced into the side chains during the preparation process, which can also introduce new properties into the material.

[0040] Specifically, the initiator has the following functions: starting the reaction. The initiator can start the chemical reaction by providing activation energy or changing the activity of the reactants; reducing the activation energy. In a chemical reaction, the initiator can reduce the activation energy required for the reaction, making the reaction easier to occur; increasing the reaction rate. The presence of the initiator can increase the rate of the chemical reaction and make the reaction reach equilibrium faster; controlling the polymerization process. In a polymerization reaction, the initiator not only initiates the polymerization reaction of the monomers, but also its type and amount directly affect the properties of the polymer, such as the molecular weight, molecular weight distribution and morphology of the polymer.

[0041] Furthermore, the preparation method of the polymer material comprises the following steps:

[0042] After removing the solvent from the solution containing the lipoic acid polymer, a lipoic acid polymer elastomer is obtained;

[0043] Adding lipoic acid polymer elastomer and epoxy compound into solvent to react, thereby obtaining polymer material;

[0044] The ratio of lipoic acid polymer elastomer to epoxy compound is carboxyl group:epoxy group=200:(1-200).

[0045] Furthermore, the solvent is at least one of acetone, butanone, toluene, tetrahydrofuran, dimethyl sulfoxide, butyl sulfone, N-methylpyrrolidone, N,N-dimethylformamide, N,N-dimethylacetamide, and anisole.

[0046] Specifically, the solvent can be selected according to the reaction temperature to improve the reaction efficiency.

[0047] Further, the catalyst includes dibutyltin dilaurate, dioctyltin dilaurate, stannous octoate, dibutyltin di(dodecylsulfide), dibutyltin diacetate, dibutyltin dimaleate, butyltin dithiol, dioctyltin mercaptan, tin acetylacetonate, organic bismuth, chromium trichloride, chromium 3,5-diisopropylsalicylate, chromium 5-tert-butylfurancarboxylate, chromium 5-isopropylfurancarboxylate, chromium 2-ethylhexanoate, fatty acid chromium, chromium acetylacetonate, molybdenum acetylacetonate, aluminum acetylacetonate, cobalt (II) acetylacetonate, cobalt (III) acetylacetonate, manganese acetylacetonate, zirconium acetylacetonate, vanadium acetylacetonate, vanadium acetylacetonate, Ruthenium acetylacetonate, iron acetylacetonate, cobalt acetylacetonate, nickel acetylacetonate, titanium acetylacetonate, palladium acetylacetonate, gallium acetylacetonate, rhodium dicarbonyl acetylacetonate, neodymium (III) acetylacetonate, trifluoromethanesulfonates of the lanthanides (yttrium, scandium, dysprosium, samarium, gadolinium and neodymium), manganese perchlorate, magnesium perchlorate, calcium perchlorate, cesium perchlorate, barium perchlorate, iron perchlorate, zinc dichloride, cadmium dichloride, mercury dichloride, aluminum trichloride, aluminum tribromide, gallium trichloride, iron trichloride, tin tetrachloride, titanium tetrachloride, zirconium tetrachloride, vanadium tetrachloride, antimony pentafluoride, antimony pentachloride, tungsten pentachloride, boron trichloride, boron trifluoride, boron tribromide, AlR m X 3-m (R is an alkyl group such as methyl or ethyl, and X is a halogen), triazine trimerization catalyst, bis(dimethylaminomethyl)benzene, N,N-dimethylbenzylamine, N,N-diethylbenzylamine, triethylamine, triethanolamine, N,N-dimethylethanolamine (DMEA), tetrabutylammonium bromide, triethylbenzylammonium chloride, pyridine, N,N'-lutidine, sodium hydroxide, potassium hydroxide, sodium bicarbonate, sodium carbonate, triphenylphosphine, triphenylphosphine sulfide, dibromotriphenylphosphine At least one of phosphine, dichlorotriphenylphosphine, triphenylphosphine borane, triphenylphosphine hydrobromide, triphenylphosphine diiodide, N-tert-butyloxycarbonyl-amidine triphenylphosphine, triphenylphosphine rhodium chloride, triphenylphosphine palladium acetate, bis(triphenylphosphine)ammonium chloride, tetrakis(triphenylphosphine)palladium, bis(triphenylphosphine)dicarbonylnickel, tris(triphenylphosphine)cobalt chloride, bis(triphenylphosphine)cobalt chloride, bis(triphenylphosphine)palladium dichloride (II), and dichlorotetrakis(triphenylphosphine)ruthenium.

[0050] Specifically, in the presence of an appropriate catalyst, the epoxide atom can be attacked by the carbonyl carbon in the carboxyl group with strong electrophilicity, opening the ring to form an intermediate. In this process, the carbon-oxygen bond is broken, a negative ion is formed on the oxygen atom, and a positive ion is formed on the carbonyl carbon of the carboxyl group. The intermediate is relatively unstable and prone to subsequent nucleophilic substitution reactions. The negatively charged oxygen atom combines with the positively charged carbon atom to form a new carbon-oxygen bond to obtain an esterification product. At the same time, the oxygen atom of the hydroxyl group on the carboxyl group is connected to the carbon atom of the epoxide to form an alcohol. Polylipoic acid or lipoic acid-styrene copolymer converts the carboxyl group on the molecular chain into a hydroxy ester group through a derivatization reaction, and introduces different structures into the side chain.
