| 摘 要：用溶液聚合法合成了聚丙烯酸系樹(shù)脂(PAAS)。研究了反應溫度、單體濃度、引發(fā)劑用量、交聯(lián)劑用量及單體中和度對PAAS吸液性能的影響,得到了合成PAAS的較佳工藝條件。此條件下合成的產(chǎn)物在蒸餾水中的吸液倍率為1430g·g-1,在0 9%(m)的NaCl溶液中的吸液倍率為102g·g-1。同時(shí)也考察了PAAS在不同離子強度的NaCl、CuCl2,FeCl3和Mg Cl2、CaCl2、BaCl2以及KCl、KBr、KI溶液中的吸液性能。 |

| Abstract：Acrylic-Based Polymer(PAAS) was synthesized by aqueous solution polymerizatioin. The influences of monomer concentration, the neutralization, the concentrations of crosslinker, initiator, and the reaction temperature on the absorbency of PAAS were studied, the results showed that the absorbency was of PAAS 1430g/g in distilled water, and 102g/g in 0.9 wt% NaCl solution. The absorbencies of PAAS in different ionic strength of NaCl, CuCl_2, FeCl_3 and MgCl_2,CaCl_2,BaCl_2 and KCl, KBr, KI solutions were given... |
| Key words：poly（acrylic acid）; aqueous solution polymerization; absorbency; ionic strength |
