摘要
通过PAM/月桂酸钠(R^1 COONa)混合溶液比浓粘度和紫外一可见吸收光谱的测定,考察了两者之间的相互作用机理.结果表明,在中性或弱酸性溶液中,PAM大分子可与R^1COOH发生氢键缔合,而 R^1 COOH则以疏水力与R^1 COO^-缔合成二聚体、预胶束或胶束,从而使PAM大分子链上带有大量电荷,混合溶液表现出聚电解质的粘度行为.
The interaction between polyacrylamide (PAM) and sodium laurate (R1 COONa) have been studied by viscosity and UV-vis spectroscopy. The reduced viscosity measurements show that PAM/R1 COONa mixed solution exhibits viscometric behavior of polyelectrolyte. UV-vis spectra indicated that hydrogen bond was formed between PAM and R1 COOH. And R1 COOH-R1 COO- premicelle or micelle was bound to the macro molecule of PAM to form polymer-surfactant complex.
