【摘要】：为揭示疏水缔合聚合物(HMPAM)与非离子表面活性剂壬基酚聚氧乙烯醚(TX)间的相互作用规律,通过测量HMPAM/TX二元体系的表观黏度、荧光光谱和流变性研究了HMPAM与环氧乙烷(EO)数不同(4~15)的TX间的相互作用,分析了二者相互作用的变化规律。结果表明,HMPAM/TX二元体系宏观黏度的变化是由混合疏水微区微观结构与数量及体系中空间网络结构的变化引起的。HMPAM与TX系列表面活性剂相互作用的强弱为TX-4TX-7TX-10TX-13≈TX-15,按EO数的不同将其相互作用分为三种:(1)EO数为4~7,以TX-4、TX-7为代表,只表现出协同作用;(2)EO数为8~12,以TX-10为代表,既有协同作用又有"负作用";(3)EO数为13~15,以TX-13、TX-15为代表,只有"负作用"。
[Abstract]:In order to reveal the interaction between the hydrophobically associating polymer (HMPAM) and nonylphenol polyoxyethylene ether (HMPAM/TX), the apparent viscosity of HMPAM/TX binary system was measured. The interaction between HMPAM and TX with different number of ethylene oxide (EO) was studied by fluorescence spectroscopy and rheology. The results show that the change of macroscopic viscosity of HMPAM / TX binary system is caused by the microstructure and quantity of mixed hydrophobic microregion and the change of spatial network structure in the system. HMPAM and TX series are active on the surface. The strength of the interaction is TX-4TX-7TX-10TX-13 鈮，
