耐温耐盐双尾型疏水缔合聚合物的制备与性能
Preparation and properties of temperature and salt resistant double-tailed hydrophobically associated polymer
摘要
Abstract
Using monomers acrylamide(AM),sodium 2-acrylamido-2-methylpropanesulfonate(SAMPS),sodium acrylate(SA),dimethyl diallyl ammonium chloride(DMDAAC),and didecyl methyl allyl ammonium chloride(DC10MAAC),a double-tailed hydrophobically associated polymer(PASSDD)was obtained through free radical polymerization.The structure of the PASSDD was characterized and its properties were investigated by methods such as IR,1H NMR,AFM,and viscosity testing.The results indicate that the suitable reaction conditions for synthesizing PASSDD are n(AM)∶n(SAMPS)∶n(SA)∶n(DMDAAC)∶n(DC10MAAC)=71.25∶7.5∶20∶1∶0.25.When the initiator dosage is 0.15%(w),the reaction temperature is 45℃,the total monomer dosage is 25%(w),and the OP-10 dosage is 1.2%(w),the PASSDD solution obtained has the best viscosity increasing ability.Compared with partially hydrolyzed polyacrylamide(HPAM),PASSDD with different hydrolysis degrees exhibits good ability in viscosity increasing and shear resistance under high temperature and high mineralization conditions.PASSDD has good anti-aging ability.The lowest viscosity is 39.2 mPa·s after 90 d of aging.It can increase the recovery rate by 15.40%,much higher than HPAM,with a good oil displacement effect.关键词
