| Abstract: | Epichlorohydrin (ECH) and tetraethylenepentamine(TEPA) were copolymerized andthe copolymers were modified hydrophobically using a pendant C18 hydrophobic group (HPTE).Hydrophobic interaction of modified polymer was investigated by fluorescence using pyrene as aprobe. It reveals that hydrophobic microdomains are formed by aggregation of hydrophobic sidechains. The water in hydrophobic microdomains is in a state of diffusion equilibrium under thehydrophobic interaction. Critical aggregate concentration (ccac) of HPTE decreases with increas-ing content of the bound hydrophobic groups. |
