[Abstract]:In this paper, three different star hydrophobically associating water-soluble polymers have been synthesized by means of "first nucleation method" by means of single electron transfer active radical polymerization. The reaction factors and solution properties of the polymers have also been studied. The main contents of this study are as follows: 1. The ligand triamethylaminoethyl) triamethylamine Me6-TRENN was synthesized from triamethylaminoethyl triamine, formic acid and formaldehyde. The results of FTIR and 1H NMRs showed that the product was obtained by means of FT-IR and 1H NMRs. With pentaerythritol, Tetrahydrofuran and triethylamine were synthesized by acylation of 2-bromoisobutylol bromide. The star macromolecular initiator 2-pentaerythritol 2-bromoisobutyrate tetraester PT-Brine was synthesized. The product was proved to be the target product by FT-IR and 1H NMR. SET-LRP method was used. Carbon tetrachloride (CCl4) 2-pentaerythritol tetraester (PT-Br) was used as the initiator, and the Cu0 powder / Me6-TREN was used as the catalytic system. The binary star hydrophobically associating water-soluble polymer (PIAM-co-NtBA) and the ternary star hydrophobically associating water-soluble polymer (PIAM-co-NtBA) were synthesized in aqueous solution respectively. The products obtained by FT-IR and 1H NMR analysis were used as the target products. The influence of various reaction factors on the relative molecular weight of polymer was observed. The optimum conditions for the synthesis of star-type hydrophobically associating water-soluble polymers were determined. The maximum relative molecular weight of CCl_4 and PT-Br were 189 million and 2.14 million, respectively, while that of PT-Br was 2.23 million. The effect of the reaction conditions on the kinetics of the polymerization was investigated. The results showed that the polymerization time increased linearly with the increase of polymerization time, and showed a first-order kinetic relationship. The characteristics of active radical polymerization. 4. By measuring the apparent viscosity of polymer solution at different temperature and salt concentration, the temperature resistance and salt resistance of star hydrophobically associating water-soluble polymer were studied. The solution properties of star-shaped polymers are similar to those of linear polymers, but the apparent viscosity of the two kinds of polymer solutions decreases with the increase of temperature and salt concentration. The temperature and salt resistance of star polymer is slightly better than that of linear polymer, and the effect of CaCl_2 on the apparent viscosity of the polymer is greater than that of NaCl at the same salt concentration.
