The results showed that the interaction between PAA and PEO led to formation of the PAA/PEO complex with more expanding conformation and larger hydrodynamic volume,ressulting in an enhancement in solution viscosity.

• 结果表明 :PAA/ PEO复合溶液结构不同于PAA和 PEO两组分聚合物溶液结构 ,PAA与 PEO高分子链间的氢键相互作用形成构象更为伸展、流体力学体积更大的 PAA/ PEO氢键复合物 ,导致溶液粘度升高 ,复合增粘效果极为显著。
