【摘要】：丙烯酰胺类共聚物是当今应用范围最广的一类高分子聚合物,由丙烯酰胺与不同单体合成的丙烯酰胺类共聚物可应用于众多领域。星形丙烯胺酰胺类共聚物相比于线性具有溶解性好、粘滞性低、流体力学体积小等优点,因此,本文选用单电子转移活性自由基聚合法(SET-LRP),来实现星形丙烯酰胺类共聚物的合成,具体内容如下:确定丙烯酰胺(AM)、N-乙烯基吡咯烷酮(NVP)为聚合反应单体,四氯化碳(CCl4)作为聚合反应的引发剂,Cu0粉作为催化剂,三(2-甲氨基乙基)胺(Me6-TREN)为配体,在水溶液中通过SET-LRP方法,合成星形丙烯酰胺二元共聚物P(AM-co-NVP)。经过红外光谱(FT-IR)和核磁共振碳谱(13C-NMR)对聚合产品的表征,确定Cl端基的存在,证实目标产物的合成。以Cu0粉为聚合反应催化剂,四氯乙烷(C2H2Cl4)为聚合反应引发剂,以水为溶剂,Me6-TREN为配体,采用SET-LRP方法合成星形丙烯酰胺二元共聚物P(AM-co-AMPS)。采用红外光谱(FT-IR)及核和磁共振碳谱(13C-NMR)表征所得产物的结构,结果表明所得产品为星型结构。以Cu0/(Me6-TREN)为聚合反应催化体系,四氯化碳(CCl4)为聚合反应引发剂,采用单电子转移活性自由基聚合(SET-LRP)方法,以水为溶剂合成星形丙烯酰胺三元共聚物P(AM-NVP-AA),经红外光谱(FT-IR)及核磁共振碳谱(13C-NMR)结构表征证明最终所得为目标产物。2-丙烯酰胺基-2-甲基丙磺酸(AMPS)、N-乙烯基吡咯烷酮(NVP)与丙烯酰胺进行三元共聚反应,Cu0/(Me6-TREN)作为聚合反应催化系统,以四氯化碳(CCl4)为聚合反应引发剂,采用SET-LRP法在水溶液中实现了星形丙烯酰胺三元共聚物P(AM-AMPS-NVP)的合成。通过红外光谱(FT-IR)及核磁共振碳谱(13C-NMR)对聚合产物进行表征,证明所得聚合物为目标产物。
[Abstract]:Acrylamide copolymer is one of the most widely used polymer polymers. The acrylamide copolymers synthesized from acrylamide and different monomers can be used in many fields. Compared with the linear ones, the starlike acrylamide copolymers have the advantages of good solubility, low viscosity, small hydrodynamic volume, and so on. In this paper, single electron transfer active radical polymerization (SET-LRPN) was used to synthesize star-acrylamide copolymers. The main contents are as follows: (1) Acrylamide-N-vinylpyrrolidone (NVP) was selected as the monomer of polymerization. Carbon tetrachloride (CCL _ 4) was used as initiator of polymerization, Cu0 powder was used as catalyst, trimethylaminoethyl) amine (Me6-TREN) was used as ligand, and SET-LRP method was used in aqueous solution. Star acrylamide binary copolymers, PfAM-co-NVPnP, were synthesized. The polymerization products were characterized by FT-IRIR and 13C-NMRs. The existence of Cl terminal group was confirmed, and the synthesis of the target product was confirmed. Cu0 powder was used as the catalyst for polymerization. Tetrachloroethane (C _ 2H _ 2Cl _ 4) as initiator and water as solvent Me6-TREN as ligand, a binary copolymer of star-acrylamide, PfAM-co-AMPSN, was synthesized by SET-LRP method. The structure of the product was characterized by FT-IRIR and 13C-NMRs of nuclear and magnetic resonance spectroscopy. The results show that the product is star-shaped, using Cu0 / Me6-TREN as catalyst system and CCL4) as initiator, using single electron transfer active radical polymerization (SET-LRP) method. Star acrylamide terpolymer PnAM-NVP-AAP was synthesized with water as solvent. Its structure was characterized by FT-IRIR and NMR 13C-NMRs. It was proved that the final product was. 2-acrylamido-2-methylpropanesulfonic acid (AMPS), N-vinylpyrrolidone (NVP) and N-vinylpyrrolidone (NVP). Acrylamide ternary copolymerization (Cu _ 0 / M _ 6-TREN) as a catalytic system for polymerization, Using CCL 4) as initiator, the star acrylamide terpolymer (PnAM-AMPS-NVPN) was synthesized in aqueous solution by SET-LRP method. The polymerization products were characterized by FT-IRIR and 13C-NMRs. It is proved that the obtained polymer is the target product.
