Uncontrolled accumulation of synthetic materials in the environment led to ecological problems, due to their resistance to chemical or biological degradation. One strategy to augment the biodegradability of convenient polymers involves introducing more hydrolysable groups into their structure. Exceptionally important representatives of biodegradable polymers are pseudo-proteins - a new family of synthetic biodegradable polymers based on natural α-amino acids. One of the members of pseudo - proteins class of polymer include poly(ester amide)s, which are characterized by easily synthesis and versatile application.

During the research Poly (Amide-co-Ester Amide)s were synthesized via interfacial polycondensation reaction mechanism, between monomers: Hexamethylenediamine (HDMA) and Tosyl diamine diesters (TDADE) with various diacid chlorides. Solubility of obtained products was studied in various solvents. Structures were checked by FTIR and NMR spectroscopy methods. Mechanical properties were evaluated using Tensile Testing Machine.
