Transition metal removal using novel polyamides bearing calix[4]arene in their backbones and characterization of their thermophysical properties

In the last decade, huge efforts have been performed to incorporate new functionalities in the polyamide backbone to combine their intrinsic thermal/mechanical properties with adesired capability to approach novel industrial application of these materials. One of the extraordinary organic compoundsthat have drawn considerable attention are calixarene family. Many attempts have been performed for the development of novel calixarene derivatives, such as molecular calixarene orits polymeric analogues [1-3]. Herein we attempted to produce a kind of polyamides with low Tgs and good solubility as aresult of existence of bulky calixarene in polymer backbone, but with maintaining its characteristic features as a cation receptor with promising high thermal stability
