Novel Hydrophobically Modified Polyelectrolytes: Synthesis and Characterization of Phospholipid-Containing Polyampholytes |
초록 |
The phosphatidyl derivatives of ethyl 3-aminocrotonate were synthesized for the first time from acetoacetic ester and phosphatidylethanolamine in the bulk, ethanol, and chloroform under mild conditions. They were involved ina Michael addition reaction with acrylic acid followed by radical polymerization. The polymers bearing both hydrophobic tails and betaine groups were characterized by FTIR, NMR, and UV-Vis spectroscopy as well as by TGA and DSC. The phase transition temperatures from the crystalline to the liquid crystalline as well as from the liquid crystalline to the isotropic state were determined. The conformational transition from the globular structure to the coiled one was evaluated from potentiometric titration and viscometry. The ability of phospholipid-containing polymers to solubilize hydrophobic molecules was shown. |
