摘要：
The surface dilational viscoelasticities of octylphenol polyoxyethylene ethers solutions, TX-100(10 oxyethylene (M), TX-102(12EO) and TX-165(16EO), were investigated by Langmuir trough method. The influences of polyoxyethylene numbers on surface dilational properties were expounded. It showed that the increase of polyoxyethylene numbers resulted in the increase of surface dilational modulus and elasticity, which may be attributed to the slower relaxation processes caused by the "flat-configuration" of the longer polyoxyethylene chain at the surface.
