首先制备了疏水单体2-丙烯酰胺基十四烷磺酸,在此基础上又以改性SiO2功能单体为反应核制备了超支化疏水缔合聚合物( HBPAM),结构经红外光谱( FTIR)和核磁共振氢谱(1 H NMR)表征证实。 HBPAM在低浓度时主要是分子内缔合,表观黏度低,随着浓度的增加,分子内缔合逐渐变为分子间缔合,又因其独特的三维立体网状结构,溶液黏度显著增加。与梳形KYPAM相比,HBPAM在耐温抗盐及抗剪切方面有较高的优势：升温到85℃时黏度保留率为62．2%；100000mg·L-1 NaCl、150000 mg·L-1 NaCl、500 mg·L-1 MgCl2、1000 mg· L-1 MgCl2、500 mg·L-1 CaCl2、1000 mg·L-1 CaCl2时的黏度保留率分别为233．0%、132．9%、64．4%、26．1%、66．2%、15．7%；3400rpm/min剪切30s后HBPAM的黏度保留率为69．8%,比KYPAM高10．9%。在60℃烘箱中的30d老化实验证明,HBPAM比KYPAM有明显抗老化能力,尤其是在高矿化度条件下优势更明显。
首先製備瞭疏水單體2-丙烯酰胺基十四烷磺痠,在此基礎上又以改性SiO2功能單體為反應覈製備瞭超支化疏水締閤聚閤物( HBPAM),結構經紅外光譜( FTIR)和覈磁共振氫譜(1 H NMR)錶徵證實。 HBPAM在低濃度時主要是分子內締閤,錶觀黏度低,隨著濃度的增加,分子內締閤逐漸變為分子間締閤,又因其獨特的三維立體網狀結構,溶液黏度顯著增加。與梳形KYPAM相比,HBPAM在耐溫抗鹽及抗剪切方麵有較高的優勢：升溫到85℃時黏度保留率為62．2%；100000mg·L-1 NaCl、150000 mg·L-1 NaCl、500 mg·L-1 MgCl2、1000 mg· L-1 MgCl2、500 mg·L-1 CaCl2、1000 mg·L-1 CaCl2時的黏度保留率分彆為233．0%、132．9%、64．4%、26．1%、66．2%、15．7%；3400rpm/min剪切30s後HBPAM的黏度保留率為69．8%,比KYPAM高10．9%。在60℃烘箱中的30d老化實驗證明,HBPAM比KYPAM有明顯抗老化能力,尤其是在高礦化度條件下優勢更明顯。

Firstly,2-acrylamidotetradecanesulfonic acid and a hyperbranched hydrophobic associating polymer( HBPAM) with modi-fied SiO2 functional monomer were prepared successively,their structures were confirmed by Fourier transform-infrared( FTIR) spec-troscopy and H nuclear magnetic resonance(1HNMR)spectroscopy,respectively. At low concentration,the intra-molecular associa-tion is occurred,reducing the apparent viscosity. With increasing of polymer concentration,intra-molecular asociation changed and intermolecular association is dominated,as well as its unique three-dimensional network structure,which enhance viscosity efficien-cy. Compared to KYPAM,HBPAM has good performance under conditions of high temperature and high salt. When the temperature rised to 85℃,the viscosity retention rate of HBPAM was 62. 2%higher than that of KYPAM;similarly,the viscosity retention rate was 233. 0%,132. 9%,64. 4%,26. 1%,66. 2%,15. 7%higher than that of KYPAM in 100000mg·L-1 NaCl,150000mg·L-1 NaCl,500mg·L-1 MgCl2 ,1000mg·L-1 MgCl2 ,500mg·L-1 CaCl2 ,1000mg·L-1 CaCl2 brine,respectively;after suffering from super high shear force(3400rpm/min)for a period of 30s,the viscosity retention rate was 69. 8%,10. 9%higher than KYPAM. The vis-cosity of HBPAM was much better than KYPAM after encountering 30 days aging at the temperature oh 60℃.
