Polyamides incorporating furan moieties: 4. Synthesis, characterisation and properties of a homologous series

Interfacial polycondensation of 2,2 ' -bis[2-(5-chloroformylfuryl)]propane with various diamines gave high yields of a novel series of furanic polyami des with high inherent viscosities. The properties of these polymers (T-g, surface energy, crystallinity, thermal stability) were assessed and examine d in terms of the role of the specific structure of the bridging group born e by the diamines. Only three polyamides were partially crystalline, wherea s all the others were amorphous. Thermogravimetric analysis revealed that t hermal decomposition began above 300 degreesC in all instances.
