摘　　要：以十六烷基二甲基烯丙基氯化铵(C_(16)DMAAC)为疏水单体、烯丙基环糊精(A-CD)为环糊精功能化单体,与丙烯酰胺(AM)通过自由基共聚作用制备了环糊精功能化疏水缔合丙烯酰胺聚合物P(AM/A-CD/C_(16)DMAAC)。采用红外光谱和电子扫描电镜对P(AM/A-CD/C_(16)DMAAC)的结构进行表征。并考察了聚合物的水溶性、粘浓性质、特性粘数和粘均分子量。发现聚合物具有良好的空间结构和溶解特性,临界缔合浓度为1600mg/L,粘均分子量达5.5×10^(6)g/mol,聚合物具备作为三次采油的应用潜能。Cyclodextrin functional hydrophobically associating acrylamide copolymer P(AM/A-CD/C_(16)DMAAC) was prepared by free radical copolymerization with acrylamide(AM) using hexadecyldimethyl allyl ammonium chloride(C_(16) DMA AC) as hydrophobic monomer and allyl cyclodextrin(A-CD) as cyclodextrin functional monomer.The structure of P(AM/A-CD/C_(16)DMAAC) was characterized by infrared spectroscopy and electron scanning electron microscopy.The water solubility,viscosity-concentration property,intrinsic viscosity number and average molecular weight of the polymer were also investigated.It was found that P(AM/A-CD/C_(16)DMAAC) has good spatial structure and dissolution properties,and the critical association concentration is 1600mg/L,and the average molecular weight of the polymer is 5.5×10^(6) g/mol.The polymer has the potential to be used as tertiary oil recovery.
