中文摘要:
      以二甲氨基丙基甲基丙烯酰胺和溴代十六烷为原料,丙酮为溶剂,合成了一种疏水单体二甲基十六烷基(2-甲基丙烯酰胺基丙基)溴化铵(DHAB) ,并以DHAB、2-甲基-2-丙烯酰胺基丙磺酸(AMPS)和丙烯酰胺(AM)为单体,以自由基水溶液聚合法合成了一种疏水缔合聚合物PAAD-16,用IR、FL和SEM对其进行了结构表征。结果表明:PAAD-16的酸溶时间约为90min;以该疏水缔合聚合物为主要添加剂配制而成的稠化酸在30 ℃、170 s-1下的表观黏度为59mPa·s,在60、90℃下的热稳定性ω分别为85.0%和66.1%,在 30 ℃、170 s-1下连续剪切 120 min 后剪切稳定性ω'为 81.4%,具有良好的增黏性、耐温抗剪切性和缓速性能。
英文摘要:
      A hydrophobic?monomer was synthesized by using amino propyl intermediates dimethyl methyl acrylamide (DMAPMA) and 1-bromohexadecane. The new hydrophobically associating copolymer PAAD-16 has been prepared by aqueous solution polymerization , which can be used as an acid thicker and the monomers are acrylamide(AM), anionic monomer 2-acryamido-2-methylpropane sulfate acid (AMPS) and DHAB. And it had been characterized by means of IR, FL and SEM. Evaluated the performance of the PAAD-16, and the results show that the acid dissolving time of this thickener is about 90 min; the apparent viscosity of this viscous acid is 59mPa·s at 30 ℃ and 170 s-1; ω of this viscous acid was respectively 85.0% and 66.1% at 60 ℃ and 90 ℃. Under the conditions of 30 ℃, 170 s-1, ω' of this viscous acid is 81.4%, it has excellent viscosity increasing, temperature resistance, shear resistance and retarding performance. Key words: hydrophobic association; polymer; thickener;acid solution
