PhD Dissertation at the University of Samarra Explores the Preparation, Characterization, and Applications of Copolymeric Derivatives in Biomedical and Industrial Fields

A PhD dissertation at the College of Education, University of Samarra, titled “Preparation and Characterization of Copolymeric Derivatives of Hydroxymethyl Acrylamide and the Study of Their Biomedical and Industrial Applications,” was presented by Assistant Lecturer Haider Mohammed Saleh, a faculty member in the College of Applied Sciences at the university.

The researcher aimed to prepare and characterize a series of copolymers formed by hydroxymethyl acrylamide and acrylic acid monomer at both low and high conversion rates. He also sought to study the effectiveness ratios of the copolymers synthesized using various methods to determine their types. Additionally, the study investigated gel properties such as expansion ratio (ER), polymer volume fraction (ɸ1), shrinkage, swelling, and the impact of the cross-linking factor on water content (EWC%) under different conditions.

Mohammed concluded that the reaction of AA (0.248) is of the same order as that of HMA (0.282) due to the presence of amide and carbonyl groups in both AA and HMA units. The copolymer exhibited an alternating behavior with high conversion success when mixing polymers at different concentrations. Most of the dry gels showed good performance in removing iron from the industrial wastewater of the Samarra pharmaceutical plant.

The Media and Government Communication Department at the University of Samarra congratulated Assistant Lecturer Haider Mohammed Saleh on his advancement in the field of chemistry and wished him continued success in his academic journey.
