Abstract: | A novel cationic-nonionic bifunctional polymerizable surfactant (PEP) was prepared by the quaternarization of poly (ethylene oxide-propylene oxide) block polymers (PEO-PPO) having terminal tertiary amine group with chloropropene. Polymeric surfactant (PAM-g-PEP) was prepared by the copolymerization of acrylamide and PEP in water and the product was confirmed by FTIR. PAM-g-PEP has exhibit excellent surface and interfacial activity and its surface tension and interfacial tension at cmc are 40.13 mN/m and 11.69 mN/m, respectively. The influence of temperature on the micellar behavior of the PAM-g-PEP in water was studied by the dynamic laser scatting (DLS) and ultraviolet spectroscope. The results showed that PAM-g-PEP in water is thermo-associative. In diluted PAM-g-PEP solution, the Rh of the polymeric surfactant increases with the temperature due to the interpolymeric aggregations are formed. In the case of concentrated PAM-g-PEP solution, the light transmittance of PAM-g-PEP aqueous solution decreases with the increasing temperature, which is may be caused by the increase of the number of the interpolymeric PEP chain aggregates. ![id=](/na101/home/literatum/publisher/tandf/journals/content/ldis20/2014/ldis20.v035.i02/01932691.2013.771364/20140220/images/medium/ldis_a_771364_o_uf0001.jpg) |
