【摘要】:丙烯酰胺類共聚物是當今應用范圍最廣的一類高分子聚合物,由丙烯酰胺與不同單體合成的丙烯酰胺類共聚物可應用于眾多領域。星形丙烯胺酰胺類共聚物相比于線性具有溶解性好、粘滯性低、流體力學體積小等優(yōu)點,因此,本文選用單電子轉移活性自由基聚合法(SET-LRP),來實現(xiàn)星形丙烯酰胺類共聚物的合成,具體內容如下:確定丙烯酰胺(AM)、N-乙烯基吡咯烷酮(NVP)為聚合反應單體,四氯化碳(CCl4)作為聚合反應的引發(fā)劑,Cu0粉作為催化劑,三(2-甲氨基乙基)胺(Me6-TREN)為配體,在水溶液中通過SET-LRP方法,合成星形丙烯酰胺二元共聚物P(AM-co-NVP)。經(jīng)過紅外光譜(FT-IR)和核磁共振碳譜(13C-NMR)對聚合產(chǎn)品的表征,確定Cl端基的存在,證實目標產(chǎn)物的合成。以Cu0粉為聚合反應催化劑,四氯乙烷(C2H2Cl4)為聚合反應引發(fā)劑,以水為溶劑,Me6-TREN為配體,采用SET-LRP方法合成星形丙烯酰胺二元共聚物P(AM-co-AMPS)。采用紅外光譜(FT-IR)及核和磁共振碳譜(13C-NMR)表征所得產(chǎn)物的結構,結果表明所得產(chǎn)品為星型結構。以Cu0/(Me6-TREN)為聚合反應催化體系,四氯化碳(CCl4)為聚合反應引發(fā)劑,采用單電子轉移活性自由基聚合(SET-LRP)方法,以水為溶劑合成星形丙烯酰胺三元共聚物P(AM-NVP-AA),經(jīng)紅外光譜(FT-IR)及核磁共振碳譜(13C-NMR)結構表征證明最終所得為目標產(chǎn)物。2-丙烯酰胺基-2-甲基丙磺酸(AMPS)、N-乙烯基吡咯烷酮(NVP)與丙烯酰胺進行三元共聚反應,Cu0/(Me6-TREN)作為聚合反應催化系統(tǒng),以四氯化碳(CCl4)為聚合反應引發(fā)劑,采用SET-LRP法在水溶液中實現(xiàn)了星形丙烯酰胺三元共聚物P(AM-AMPS-NVP)的合成。通過紅外光譜(FT-IR)及核磁共振碳譜(13C-NMR)對聚合產(chǎn)物進行表征,證明所得聚合物為目標產(chǎn)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.
