| Abstract: | The new active β-alanine and glycine esters ( 6 and 7 ) of N-hydroxy-2,3-dihexadecylsuccinimide were prepared and their polycondensation was studied. The aggregation behavior of these esters was examined by an electron microscopy and an osmotic method. They formed multilamella in water and reversed micelle in nonpolar solvents. These solvents were found to be suitable for the polycondensation, which gave the corresponding poly(amino acid)s. The results of polycondensation can be explained by assuming that the aggregations, that is, multilamella in water and reversed micelle in nonpolar solvents, are playing an important role in the polycondensation. |
