摘要
以自制的疏水单体苯乙烯衍生物(STD)和丙烯酰胺(AM)、2-甲基-2-丙烯酰胺基丙磺酸钠(NaAMPS)为原料,合成了三元疏水缔合水溶液共聚物PASA。用红外光谱、核磁共振1H谱和DSC分析证实了共聚物的结构,采用元素分析测定了聚合物的组成,通过原子力显微镜对聚合物溶液形态的表征,证实了PASA水溶液疏水微区的存在。TG分析显示PASA具有优良的耐热性能,其分解温度高达312℃。PASA浓度为0.1g/dL时,表观粘度达208mPa.s,表明了其聚合物具有优良的增粘能力。
The hydrophobic monomer styrene derivation was synthesized. Hydrophobically associating water-soluble terpolymer PASA of acrylamide(AM), styrene derivation(STD)and sodium-2-acrylamido-2-methylpropane sulphonate(NaAMPS)was prepared. The copolymer structures were determined by FT-IR spectroscopy, ()~1H-NMR spectroscopy and DSC analysis. Elemental analysis was used in determining polymer composition. Characterization of polymer solution appearance by AFM revealed the existence of hydrophobic region of copolymer PASA solution. The excellent heat properties of PASA were determined by TG analysis, the decomposition temperature of PASA is up to 312 degress. The apparent viscosity of solution containing 0.1g/dL polymer is up to (208.5) mPa·s. The ageing experiment of PASA solution revealed that the copolymer PASA has good antiaging properties.
