Vesicles prepared from amphiphilic copolymers

摘要

Two amphiphilic monomers from aspartic acid, N-methacryloyl dihexadecyl L-aspartate (A16-MA) and N-itaconyl dioctadecyl L-aspartate (A16-I) were synthesized. Three kinds of amphiphilic copolymers were botained salt (SPMAP) respectively and of A16-I with HEMA. The aggregation behavior of the two monomers and three copolymers were examined in an aqueous system. A16-MA and its copolymers with HEMA are very difficult to disperse in water to form regular aggregates; however, copolymers form A16-MA and SPMAP can be dispersed in aqueous media as stable vesicles.
