College of Education, Samarra University discussed a Ph.D. thesis on  preparation and characterization of copolymer derivatives of hydroxymethylacrylamide and studied their biomedical and industrial applications by the postgraduate student, Mr. Haider Muhammad Salih.

The thesis aimed at preparing and characterizing a series of copolymers (hydroxymethylacrylamide with acrylic acid monomer) at low and high conversion rates.

The thesis reviewed studying the activity ratios of copolymers prepared using various methods to determine their type, as well as reviewing gel properties such as the expansion ratio (ER), polymer volume fraction (ɸ1), shrinkage, swelling, and the effect of the crosslinking agent on water content (EWC%) under different conditions.

The thesis concluded that the reaction of AA (0.248) is of the same order as the reaction of HMA (0.282) due to the presence of amide and carbonyl groups for both AA and HMA units, as well as copolymer highlighted a high conversion alternating behavior successfully by mixing polymers with different concentrations, most of the dry gels showed good performance in removing iron metal from the industrial wastewater of Samarra pharmaceutical factory.
