STUDIES ON SYNTHESES AND PROPERTIES OF NOVEL POLYAMIDES CONTAINING PHOSPHATIDYLCHOLINE ANALOGOUS MOIETIES BY INTERFACIAL POLYCONDENSATION

Polyamides (4a-b and 5a-b) were synthesized from interfacial polycon d ensation of novel diamine containing phosphatidylcholine analogous moi ety, hexamethylene diamine with adipoyl chloride, or sebacoyl chloride in the interface of water and carbon tetrachloride at room temperatur e. The characterizations of synthesized diamine and polyamides were ca rried out with FT-NMR, or IR spectral method, elemental analysis, and melting point measurements, respectively. These polyamides obtained ar e insoluble in any normal solvents. From the results of X-ray diffract ion analysis and POM observation, it was revealed that the polyamide 4 b was prepared with high molecular weight, while polyamide 4a obtained seemed to have low molecular weight. For copolymers 5a and 5b, X-ray reflections from only adipoyl or sebacoyl chloride parts were observed as in crystalline state. In addition, thermal properties were also st udied by DSC and transmitted Light intensity measurements. (C) 1997 Jo hn Wiley & Sons, Inc.
