Definitions
- the invention relates to a polymer and a preparation method thereof, and belongs to the field of polymers.
- Self-assembly at the nanoscale is a key property that nature relies on to generate biological membranes.
- These membranes build a functionalized molecular framework by embedding a combination of channels, receptors, and molecular pumps in the microenvironment and functional framework. Using hydrophobic-hydrophilic interactions, these membranes self-assemble into bilayers and other structures such as vesicles.
- Self-assembled membranes are a key component if one wishes to mimic the principles of natural nanostructures.
- a range of polymer systems have been used for drug delivery, biopharmaceutical coatings, virus-assisted gene delivery, and nanoreactors through their self-assembly. These are amphiphilic diblock or triblock copolymers that self-assemble in suitable solvents into micelles, worm-like micelles, tubular structures, membranes, or vesicles.
- ABA triblock copolymers Although there are many different types of block copolymer structures, ABA triblock copolymers have received particular attention in recent years due to their inherent ability to form vesicular structures by self-assembly despite being highly hydrophobic and hydrophilic. From a biomedical perspective, polyoxazolines are particularly attractive because they provide a pseudopolypeptide architecture and were chosen as the hydrophilic block A.
- Polymethylsiloxane (PDMS) exhibits a very low glass transition temperature and is mostly liquid at room temperature due to the ionic nature of the Si- CH3 bond.
- poly(siloxanes) have very low surface energy and are extremely hydrophobic; therefore, they were chosen as the hydrophobic block B. This type of ABA triblock copolymer system has been extensively studied and has been shown to have interesting biomedical and self-assembly properties.
- the existing synthesis method constructs a series of ABA triblock backbone structure polymers through a core-first synthesis strategy, but it has the disadvantages of many synthesis steps, low yield, high polymer dispersibility, poor repeatability, and difficulty in modifying the molecular structure.
- the existing technology provides a small amount of triblock polymer preparation schemes, such as the following preparation method, which realizes the preparation of single hydroxyl-terminated triblock polymer PMOXA-PDMS-PMOXA through 4-5 steps.
- the process steps are too long, and it involves metal lithium reagents with poor stability and pyridine with high toxicity, which seriously pollutes the environment and is not conducive to industrial large-scale production.
- the technical problem to be solved by the present invention is that the existing method for synthesizing block copolymers has many synthesis steps, involves metal lithium reagents with poor stability, pyridine and other reagents with high toxicity, low yield, high polymer dispersibility, poor repeatability, and difficult molecular structure modification.
- the present invention provides a polymer and a preparation method thereof.
- the present invention provides a polymer represented by formula V:
- the R is -ORt1 , -NRt2Rt3 , -COOMe , -( CH2 ) n1SH , a 5-10 membered heteroaryl substituted by 1, 2 or 3 oxo groups, -O( CH2 ) n2OH , -OP(O)(OMe), -OP(O)(OMe)(O( CH2 ) n3N + (Et) 3 ,
- R t1 , R t2 , and R t3 are independently H, Ts, C 1 -C 6 alkyl or -(CH 2 ) n4 SH;
- n1, n3 and n4 are independently 0, 1, 2, 3, 4, 5 or 6;
- n2 is 2, 3, 4, 5, 6, 7, 8 or 9;
- the L is a

Description
本发明涉及一种聚合物及其制备方法，属于聚合物领域。The invention relates to a polymer and a preparation method thereof, and belongs to the field of polymers.
纳米尺度上的自组装是自然界产生生物膜所依赖的关键性质。这些膜通过在微环境和功能框架中嵌入通道、受体和分子泵的结合，构建了一个功能化的分子框架。利用疏水-亲水相互作用，这些膜自组装成双层和囊泡等其他结构。如果希望模仿自然纳米结构的原理，自组装膜是一个关键的组成部分。近年来，一系列聚合物体系通过其自组装，被用于药物递送，生物药物涂层，病毒辅助基因传递，以及纳米反应器。这些是两亲性二嵌段或三嵌段共聚物在适宜的溶剂中自组装成胶束，蠕虫状胶束，管状的结构、膜或囊泡。Self-assembly at the nanoscale is a key property that nature relies on to generate biological membranes. These membranes build a functionalized molecular framework by embedding a combination of channels, receptors, and molecular pumps in the microenvironment and functional framework. Using hydrophobic-hydrophilic interactions, these membranes self-assemble into bilayers and other structures such as vesicles. Self-assembled membranes are a key component if one wishes to mimic the principles of natural nanostructures. In recent years, a range of polymer systems have been used for drug delivery, biopharmaceutical coatings, virus-assisted gene delivery, and nanoreactors through their self-assembly. These are amphiphilic diblock or triblock copolymers that self-assemble in suitable solvents into micelles, worm-like micelles, tubular structures, membranes, or vesicles.
虽然嵌段共聚物的结构有很多种，ABA三嵌段共聚物近些年来得到了特别的关注，因为其具有通过自组装形成囊泡结构的固有能力，尽管具有高度的疏水性和亲水性。从生物医学的角度来看，聚恶唑啉能提供了假聚多肽体系结构，因此尤其具有吸引力，被选为亲水性嵌段A。而聚甲基硅氧烷(PDMS)，由于Si-CH
3键所具有的离子属性，则表现出很低的玻璃化转变温度，在室温下多呈现液体状态。此外，聚(硅氧烷)具有非常低的表面能和极高的疏水性；因此，他们被选为疏水性嵌段B。对这类ABA三嵌段共聚物体系的研究，得到了大量得研究，并被证明具有有趣的生物医学和自组装特性。
Although there are many different types of block copolymer structures, ABA triblock copolymers have received particular attention in recent years due to their inherent ability to form vesicular structures by self-assembly despite being highly hydrophobic and hydrophilic. From a biomedical perspective, polyoxazolines are particularly attractive because they provide a pseudopolypeptide architecture and were chosen as the hydrophilic block A. Polymethylsiloxane (PDMS), on the other hand, exhibits a very low glass transition temperature and is mostly liquid at room temperature due to the ionic nature of the Si- CH3 bond. In addition, poly(siloxanes) have very low surface energy and are extremely hydrophobic; therefore, they were chosen as the hydrophobic block B. This type of ABA triblock copolymer system has been extensively studied and has been shown to have interesting biomedical and self-assembly properties.
现有的合成方法，通过以核心优先的合成策略，构建了一系列ABA三嵌段骨架结构聚合物，但却具有合成步骤多，收率低，聚合物分散性高，重复性差，且分子结构较难修饰等缺点。The existing synthesis method constructs a series of ABA triblock backbone structure polymers through a core-first synthesis strategy, but it has the disadvantages of many synthesis steps, low yield, high polymer dispersibility, poor repeatability, and difficulty in modifying the molecular structure.
现有的技术提供了少量三嵌段聚合物的制备方案，例如下述制备方法，经过4-5步，分别实现了对单一羟基封端三嵌段聚合物PMOXA-PDMS-PMOXA的制备。工艺中步骤过长，且涉及稳定性不佳的金属锂试剂，毒性较高的吡啶等试剂，环境污染严重，不利于工业大剂量生产。The existing technology provides a small amount of triblock polymer preparation schemes, such as the following preparation method, which realizes the preparation of single hydroxyl-terminated triblock polymer PMOXA-PDMS-PMOXA through 4-5 steps. The process steps are too long, and it involves metal lithium reagents with poor stability and pyridine with high toxicity, which seriously pollutes the environment and is not conducive to industrial large-scale production.
发明内容Summary of the invention
本发明要解决的技术问题是现有合成嵌段共聚物的方法合成步骤多，涉及稳定性不佳的金属锂试剂，毒性较高的吡啶等试剂，收率低，聚合物分散性高，重复性差，且分子结构较难修饰等缺点。为此，本发明提供了一种聚合物及其制备方法。The technical problem to be solved by the present invention is that the existing method for synthesizing block copolymers has many synthesis steps, involves metal lithium reagents with poor stability, pyridine and other reagents with high toxicity, low yield, high polymer dispersibility, poor repeatability, and difficult molecular structure modification. To this end, the present invention provides a polymer and a preparation method thereof.
