چکیده مقاله:
Polyallylamine hydrochloride P(AlAm.HCl) is a cationic polymer with many applications because of the existing amines group. Its importance becomes evident as polyvinyl amine polymer cannot be prepared from its monomer via free radical polymerization. Polyvinyl sulfonic acid P(VSA) is an anionic polymer with many applications, such as drug delivery and DNA modification. The synthesis of a new amphiphilic interpolymer complex (IPC) was the aim of the study. Aqueous solutions of P(AlAm.HCl) and P(VSA.Na) were physically mixed in variant repeating unit concentrations that yielded water-insoluble IPCs. FT-IR was used to identify the structures of the IPCs, and TGA was used to determine their thermal properties. XRD patterns were performed to determine the strength of the IPCs. Strong interpolymer complexes were formed in the mole ratio (۰.۲۵:۱) in feed compositions approved by XRD and TGA. Scanning Electron Microscopy (SEM), micrographs assessed the morphology of the IPC. IPC of deacidified P(AlAm.HCl), and P(VSA) was prepared with different mole ratios of repeating units. These physical IPCs are water-soluble. FT-IR and ۱H-NMR were applied to examine the formation of sulfonamide groups and the structural characterization of IPCs between P(AlAm) and P(VSA) at different molar ratios.
